Orion constellation: how to find it, its stars and the Orion Nebula
How to find Orion by its three-star belt, the names and distance estimates of its stars, the Orion Nebula, and when Orion is best placed this winter.
Orion is one of the easiest constellations to find: look for three bright stars close together in a short, straight line. That is Orion's Belt. Around it, four bright stars mark the hunter's shoulders and feet: red Betelgeuse, blue-white Rigel, Bellatrix and Saiph. From the United States and Europe, Orion rises in the east on autumn evenings and is best seen from December to March. Just below the belt hangs a fuzzy patch, the Orion Nebula, where new stars are being born. The quick facts:
| Orion | |
|---|---|
| What it is | A constellation, one of the officially defined areas of the sky, named after a hunter in Greek mythology. Orion's Belt is a small pattern of three stars inside it |
| How to find it | Three bright stars in a row (the belt), between four bright corner stars |
| Brightest stars | Rigel and Betelgeuse |
| Best time to see it | December to March in the evening; from New York, the middle belt star is at least 20° up at 9 p.m. from about November 27 to April 16 (our calculation) |
| Where on Earth | All its main stars rise somewhere in the sky everywhere between -80 and 80 degrees latitude (our calculation) |
| Distances | Estimates for its eight main stars range from about 252 light-years (Bellatrix) to about 1,977 (Alnilam), with large uncertainties |
| Famous deep-sky object | The Orion Nebula (M42), visible to the naked eye from a dark site |
How to find Orion in the night sky
Step one is the belt. NASA's advice is to look for "three bright stars close together in an almost-straight line". The belt is 2.74 degrees long (our calculation), short enough to catch in one glance. NASA adds that two brighter stars to the north mark Orion's shoulders and two to the south mark his feet (above and below the belt, as seen from the Northern Hemisphere).
Step two: use the belt as a pointer. In the view above (New York, mid-December evening), follow the line of the belt down to the left and, about 22 degrees further, you reach Sirius, the brightest star of the night sky; it lies only 2.6 degrees off that line. Follow it up to the right and you reach the orange star Aldebaran in Taurus, 5.2 degrees off the line (our calculations from star positions in SIMBAD).
Orion's Belt is not the same as the Big Dipper. The Big Dipper is a different star pattern, far to the north, whose stars lie in the constellation Ursa Major (Ursa Major, the Great Bear; our check with Astronomy Engine, which uses the official constellation boundaries).
Where to look depends on the date and time. From New York on 15 December 2026 at 9 p.m., the belt is 32 degrees up in the southeast; by mid-January it stands at its highest point in the south at about 10 p.m. Our Stellarium Web guide shows how to check this for your own location with a free planetarium app.
The stars of Orion: names and distances
Here are Orion's eight main stars, with the brightness astronomers use (magnitude: a lower number means brighter) and their distance:
| Star | Where in the figure | Magnitude | Distance estimate from its parallax, light-years (with quoted error) | NASA's published estimate |
|---|---|---|---|---|
| Betelgeuse | right shoulder (top left as seen from the north) | 0.4 | about 498 (442 to 570) | about 550 |
| Rigel | left foot (bottom right) | 0.1 | about 863 (792 to 948) | about 860 |
| Bellatrix | left shoulder (top right) | 1.6 | about 252 (243 to 263) | not given |
| Saiph | right foot (bottom left) | 2.1 | about 647 (620 to 677) | not given |
| Alnitak | belt, left | 1.8 | about 736 (643 to 861) | about 800 |
| Alnilam | belt, middle | 1.7 | about 1,977 (1,553 to 2,718) | about 1,300 |
| Mintaka | belt, right | 2.4 | about 692 (617 to 790) | about 900 |
| Meissa | head | 3.7 | about 1,098 (927 to 1,348) | not given |
Distances to these stars are hard to measure. Astronomers use parallax: the tiny shift of a star's position as Earth goes around the Sun. Our distances come from the parallaxes of the European Hipparcos satellite, in a 2007 reprocessing of the satellite measurements by Floor van Leeuwen, as listed in the SIMBAD database. The range is what you get when you add or subtract one quoted standard error (the catalogue's usual measure of uncertainty) to the parallax. It is not a guaranteed limit: the true distance can fall outside it, and other errors are not included. For two stars, NASA's published estimates lie outside our ranges: Mintaka (about 900 light-years) and Alnilam (about 1,300). This comparison does not tell us which estimate is right. For Betelgeuse, NASA gives about 550 light-years.
Betelgeuse, Orion's "right shoulder", is a red supergiant, which is why it looks orange-red, while Rigel shines blue-white. Our Orionid meteor shower article shows where the shower's radiant lies, just north of Betelgeuse.
Orion's belt and sword
The three belt stars are, from left to right as seen from the north: Alnitak, Alnilam and Mintaka. They look like a neat row, but they are not at the same distance (see the chart further down).
Below the belt hangs Orion's sword, a short line of fainter stars. In the middle of the sword is the Orion Nebula. NASA describes it as close enough "to appear to the naked eye as a fuzzy star in the sword of the constellation". It lies about 4.2 degrees below the middle belt star (our calculation).
Close to Alnitak, the left belt star, lie two more famous clouds: the Flame Nebula and the Horsehead Nebula. They are part of a huge cloud of gas and dust that NASA calls "the giant Orion Molecular Cloud". They are much fainter than the Orion Nebula; the picture here shows them in infrared light, taken by NASA's WISE telescope.
The Orion Nebula (M42)
The Orion Nebula is a giant cloud of gas and dust where new stars are forming. NASA calls it "the closest large star-forming region to Earth". It is also known as M42, number 42 in the catalogue of the 18th-century astronomer Charles Messier.
Can you see it without a telescope? Yes: NASA says it is visible "with the unaided eye from a dark sky site" and "best observed during January". To the naked eye it looks like a "fuzzy star", as NASA puts it, not like the colourful photos. NASA's Orion page adds that binoculars give a more detailed view, and the Messier page says it offers "an excellent peek at stellar birth for those with telescopes". In its bright centre sits a small group of young stars: "The four hefty stars are called the Trapezium because they are arranged in a trapezoidal pattern." To find the nebula, locate the belt, then look just below it for the short line of the sword: the nebula is the fuzzy middle "star" of that line. Point binoculars or a telescope there and the bright centre, where the Trapezium sits, stands out. We give no telescope size for seeing the four Trapezium stars separately, because we found no official source for one.
The infrared pictures in this article show light our eyes cannot see. The colours in them are added when the image is made, so they do not show what you would see in the sky.
How far away is it? NASA pages give different published estimates: 1,300, 1,450 and 1,500 light-years. The European Gaia satellite measured the parallax of one of the Trapezium stars, θ1 Orionis C, which gives about 1,304 light-years (1,237 to 1,378; our conversion).
Orion's stars are not neighbours
From Earth, Orion looks like a flat figure. In space, the selected stars span a wide range of estimated distances, from about 252 to about 1,977 light-years. Our animation starts from Earth, where the stars form the familiar hunter, and then turns the view 90 degrees around them, using their measured distances.
Seen from the side, Bellatrix is the nearest of the eight stars compared here, about 252 light-years away. Betelgeuse is about 498 light-years from us by Hipparcos (about 550 according to NASA), Rigel about 863, and Alnilam, in the middle of the belt, roughly 1,977 light-years, though with a large uncertainty. The light you see from Bellatrix tonight left it around the year 1774; light from Rigel left it more than 800 years ago (our calculation).
They only line up into a hunter because we see them from this one place in space. From a planet near another star, the pattern would look different.
When is the best time to see Orion?
Orion is a winter constellation for the Northern Hemisphere and a summer one for the Southern Hemisphere. From New York, the middle belt star, Alnilam, is at least 20 degrees up at 9 p.m. from about November 27 to April 16, and above the horizon at 9 p.m. from November 1 to May 14 (our calculation). Here are the times for Alnilam on the 15th of each month, October 2026 to April 2027, in New York (Eastern time). All three times fall on that same date:
| Date | Rises in the east | Highest in the south | Sets in the west | At 9 p.m. |
|---|---|---|---|---|
| October 15, 2026 | 10:56 PM | 4:57 AM (48° up) | 10:55 AM | not risen yet |
| November 15, 2026 | 7:54 PM | 1:56 AM (48° up) | 7:54 AM | 12° up |
| December 15, 2026 | 5:56 PM | 11:54 PM (48° up) | 5:56 AM | 32° up |
| January 15, 2027 | 3:54 PM | 9:52 PM (48° up) | 3:54 AM | 46° up |
| February 15, 2027 | 1:52 PM | 7:50 PM (48° up) | 1:52 AM | 45° up |
| March 15, 2027 | 1:02 PM | 7:00 PM (48° up) | 1:02 AM | 40° up |
| April 15, 2027 | 11:00 AM | 4:58 PM (48° up) | 10:56 PM | 21° up |
Times that fall in daylight mean Orion is up while the Sun is still out; look in the evening instead. These times are for New York only. Your latitude changes how high Orion climbs, and your longitude, time zone and daylight-saving rules shift the clock times. From the Southern Hemisphere, you look north to see Orion, so the hunter appears upside down compared with the view from the north.
What does Orion represent?
Orion is named after a hunter. NASA writes that the ancient Greeks saw "a giant hunter with a sword attached to his belt". The belt and sword are the easiest parts to recognise; the shoulders, the feet and the star Meissa as the head complete the figure.
Orion also appears in the Bible. In the King James Version, Job 9:9 speaks of God "Which maketh Arcturus, Orion, and Pleiades", Job 38:31 asks "Canst thou bind the sweet influences of Pleiades, or loose the bands of Orion?", and Amos 5:8 says "Seek him that maketh the seven stars and Orion".
One reason Orion is so well known: it lies on the celestial equator, the line in the sky above Earth's equator. Its main stars rise at some point from almost everywhere on Earth, between about 80 degrees south and 80 degrees north (our calculation). NASA says Orion "can be seen from around the world".
Orion FAQ
What is the best time to see Orion? On winter evenings in the Northern Hemisphere, from December to March. From New York, the middle belt star is at least 20 degrees up at 9 p.m. from about November 27 to April 16 (our calculation).
What are the three stars in Orion's belt? Alnitak, Alnilam and Mintaka.
What are the three stars under Orion's belt? That is Orion's sword. Its middle "star" is really the Orion Nebula, a cloud where new stars are forming.
Where is Orion's belt right now? That depends on your location, date and time. From New York in late October 2026, it rises in the east before midnight; by mid-December it is in the southeast at 9 p.m.; in mid-January it is highest in the south at about 10 p.m. See the table above, or check your own sky with our Stellarium Web guide.

Is Orion's belt rare to see? No. It is visible every year from almost anywhere on Earth, from late autumn to early spring in the north.
Why is Orion so famous? It has several very bright stars in an easy pattern, its belt points to Sirius and Aldebaran, and it holds the Orion Nebula, the closest large star-forming region to Earth (NASA).
Which nebula is in Orion's belt? The Flame Nebula and the Horsehead Nebula lie close to Alnitak, the left belt star. The brighter Orion Nebula is in the sword, below the belt.
How far away is Orion? Distance estimates for its eight main stars range from about 252 to 1,977 light-years (Hipparcos parallaxes), and the Orion Nebula is about 1,300 light-years away.
What does the Bible say about Orion? Orion is named in Job 9:9, Job 38:31 and Amos 5:8, as one of the star groups made by God.
Where is Gemini compared with Orion? In our December evening view from New York it is to the upper left of Orion, with its two bright stars Castor and Pollux.
Are there planets around Orion's stars? NASA mentions HD 37605 b, "a giant gas world three times more massive than Jupiter", around a star in Orion. For the bigger question, see is there life on other planets?
How we checked
Star positions, brightness and parallaxes come from the SIMBAD database (CDS, Strasbourg), queried on 21 October 2026: Hipparcos parallaxes from van Leeuwen (2007), and the Gaia parallax of θ1 Orionis C for the Orion Nebula. We converted parallaxes to light-years (3,261.56 divided by the parallax in milliarcseconds). Rising and setting times, heights and angles on the sky are our calculations with the Astronomy Engine library; the sky views were simulated in Stellarium and checked against it. The Bible verses are from the King James Version. NASA facts and photos are listed under Sources. We checked all sources on 21 October 2026.
Distances to bright stars are uncertain, so we show our estimates with the quoted errors and NASA's published estimates side by side. The animation is a 3D view built from those distances. None of the images or videos is AI-generated.
