What is the Lepus Constellation?
Lepus is a constellation located just below Orion, one of the most recognisable star groups in the sky. Its name, “Lepus,” translates to “hare” or “rabbit” in Latin, and its placement is almost as if it’s being hunted by Orion the Hunter, which adds to the constellation's lore. It’s often interpreted as a hare or rabbit, hiding in the sky from its celestial predator, Orion.
What Does Lepus Look Like?
Lepus is relatively small compared to some other constellations, but it’s still noticeable with its unique shape. It consists of a collection of medium-bright stars that form an irregular quadrilateral, resembling a leaping hare. When the sky is clear, and light pollution is minimal, it can be a rewarding constellation to spot, especially if you’re already familiar with Orion. Look just beneath Orion’s belt, and Lepus will appear as if it’s sitting at the hunter’s feet.
How Far is the Lepus Constellation from Earth?
Distance in space can be tricky to comprehend, and the stars within Lepus are spread out at varying lengths from our planet. Some of the brightest stars in Lepus are hundreds of light-years away. For example, Arneb, the alpha star of Lepus, is located approximately 2,200 light-years from Earth. This immense distance makes Lepus a fascinating constellation to study, as the light you see from these stars has travelled for millennia to reach you.
The Lepus Constellation Myth
Like many constellations, Lepus is steeped in myth and legend. In Greek mythology, Lepus is often seen as a hare fleeing from Orion, the mighty hunter. The story doesn’t give Lepus the same heroic or elaborate narrative as other constellations, but its close proximity to Orion hints at an eternal chase across the sky. Some variations of the legend suggest that Lepus is associated with speed and agility, much like a real hare, symbolising quick thinking and evasion.
Lepus’ Stars
Lepus may not be among the most famous constellations, but it does host some truly remarkable stars:
- Arneb: The brightest star in Lepus, Arneb is a spectral class F0 supergiant with a magnitude of about 2.58. The name “Arneb” means “hare” in Arabic, perfectly fitting the constellation’s theme. It’s a fascinating star, situated around 2,200 light-years from Earth.
- Nihal: This yellow giant is the second brightest star in the constellation. Located approximately 160 light-years from Earth, Nihal is an interesting star that adds to Lepus’ celestial character.
- R Leporis: Also known as Hind’s Crimson Star, R Leporis is a striking red variable star. It stands out for its deep crimson hue, making it one of the most vivid red stars visible to the naked eye. Its unique colour and changing brightness make it an especially intriguing target for telescopic observation.
Nebulae in the Lepus Constellation
Lepus doesn’t just contain stars; it also features some intriguing deep-sky objects. One of the most famous is the Spirograph Nebula, or IC 418, a planetary nebula that presents a stunning pattern when viewed through telescopes.
The Spirograph Nebula is around 2,000 light-years away and showcases a bright central star surrounded by intricate, glowing gas. These beautiful formations remind us of the ongoing processes of creation and change in the universe. If you have the opportunity to view Lepus with a telescope, this nebula is a breathtaking sight to behold.
Finding Lepus in the Sky
Lepus is best observed during the winter months from the Northern Hemisphere when it sits high in the night sky, offering a clearer view of its stars.
Locating Lepus
Spotting Lepus is relatively straightforward, especially once you’ve identified the more prominent constellation Orion. To find Lepus, follow these steps:
- Identify Orion: On a clear night, start by locating Orion, one of the most recognisable constellations, known for its bright belt of three stars in a straight line.
- Move Your Gaze Downward: Once you’ve found Orion’s belt, look just beneath it. Lepus will appear as a smaller but distinct group of stars that form an irregular quadrilateral shape, resembling a hare in mid-leap.
Using Tools to Help You Find Lepus
Stargazing apps and sky maps can be valuable tools, especially if you’re new to identifying constellations. These aids can help you trace Lepus’ shape and make the constellation easier to spot in areas with light pollution or if the night sky is particularly dense with stars.
Viewing Lepus with Binoculars or a Telescope
- With Binoculars: Binoculars can enhance the view of Lepus’ stars, making them stand out more clearly. This can be especially helpful in urban areas where light pollution may dim your view of the night sky.
- With a Telescope: For a more detailed observation, use a telescope to appreciate the constellation’s features. You might even get a better glimpse of R Leporis, the vivid red variable star, or nearby nebulae that add to Lepus’ allure.
Best Viewing Conditions
To get the most out of your stargazing experience, find a dark location away from artificial lights. A moonless night is ideal, as it provides the darkest skies and makes the stars of Lepus appear brighter and more distinct.

Best SellersFun Facts About Lepus
Lepus may be smaller and often overlooked compared to larger, more famous constellations, but it boasts several fascinating features that make it worth exploring.
- A Striking Star: Lepus is home to R Leporis, also known as Hind’s Crimson Star. This is one of the reddest stars visible to the naked eye, and its vibrant hue makes it a favourite among amateur astronomers.
- Best Viewing Time: The constellation is best seen during the winter months from the Northern Hemisphere, when it’s high in the night sky and clearly visible. Its position along the celestial equator means that it can be observed from many locations around the world.
- Messier Object Rarity: Unlike many constellations near Orion, Lepus does not contain any Messier objects. This is quite unusual and adds a unique aspect to Lepus, as most neighbouring constellations boast at least one well-known deep-sky object.
