Taking into account the main stars and their individual distances, the average distance of Leo from the Earth is light-years. The Constellation Leo is a large lion, crouching in the sky with his foot raised, ready to pounce on any creature that comes close to him! In the northern hemisphere, the Lion stands upright. His huge head is identified by an asterism of stars, known as the Sickle 2.
Once you locate the Sickle — the Lion comes to life. Give it a try. Remember that in the southern hemisphere, the Lion crouches upside-down. The earliest records of Leo the constellation is thought to have come from the Mesopotamians as early as BC 3.
In ancient Chinese history, as long ago as BC, astronomers identified some of the stars of the Leo constellation as part of their constellation Xuanyuan, the Yellow Dragon. The famous Greek astronomer Ptolemy identified the constellation in the Almagest 4 in the second century AD. Scientifically, the constellation contains objects that are millions of years old.
Here are a few Leo constellation facts — the brightest star Regulus is about 1 billion years old. Leo is the fifth sign of twelve in the Zodiac family. It represents people born between July 22 and August Leo is a fire sign, together with Aries and Sagittarius.
Leo the Lion has two other zodiac constellations as neighbors in the night sky. Cancer, the Crab lies below it on the right side, and Virgo, the Virgin, is found on its left side 5. In the Zodiac family, Leo and Cancer, the Crab have a connection. They were both slain by Hercules as he carried out tasks assigned to him as punishment. Like all the Zodiac constellations, Leo zodiac lies on the ecliptic path. This is the path that the sun takes as it moves across the sky during the course of a year.
Leo is located in the eastern celestial hemisphere, together with Pisces, Aries, Taurus, Gemini, and Cancer 6. Leo, the constellation is made up of numerous stars. Some Leo constellation stars are brighter than others and many are identified for their unique attributes. What is the brightest star in the Leo constellation? The brightest star in Leo is known as Regulus. This star is also notable because it is one of the brightest stars in the sky and is about 4 times bigger than our sun.
Regulus is a four-star system and is around 80 light-years from Earth, which in astronomical terms is close! Regulus is also known as Alpha Leonis.
Also notable in the Leo star constellation is Algieba, also known as Gamma Leonis 7. This is a two-star system around light-years from Earth. The two stars orbit around one another at a distance of about 16 billion miles. In the Leo constellation, you will find an asterism called the Sickle. The 6 stars with Regulus at the base, form an easy-to-find pattern of a question mark and define the large head of the Lion 8. The first is the Leo Triplet. Also known as M66 Group, this is a group of interacting spiral galaxies.
The Leo Triplet is a great sight for astronomers as they can be seen in a single view through a basic telescope. This triplet lies about 35 million light-years from Earth 9. Another interesting deep sky object in the Leo constellation is the Leo Ring This huge cloud of helium and hydrogen gas forms a hazy light in the sky. It was discovered by accident in by a group of astronomers, Schneider et al. The Leo Ring is thought to have been created during the Big Bang.
The Big Bang Theory is a scientific explanation of how the Universe began, based primarily on mathematical formulas and models. Exoplanets are planets that revolve around other stars other than our sun. Exoplanets are exciting to astronomers as they may present conditions similar to Earth, and perhaps the possibility of life! Image credits: NASA. This star has 2 planets that orbit it. One is about the size of Saturn and the other the size of Jupiter. The star and its exoplanets are about light-years away from Earth.
Another interesting discovery in shows a large planet called GJ b. It is about 22 times the size of Earth. This planet is different from our planets in that it orbits over the poles of its star, rather than the equator. The potential existence of water is always an exciting find when looking for life in space. In , scientists discovered an exoplanet called Kb. Because it orbits in the zone of a red dwarf star that may be habitable, there is a chance that it contains water or ice.
It is located 77 light years from Earth. The second brightest star is Algiebra with a magnitude of 2. It is a binary star system that lies approximately light years away.
Denebola is the third brightest star with a magnitude of 2. It is a blue-white subgiant star located approximately 36 light years from our solar system. Leo contains five Messier objects, all of them galaxies. M65 is an intermediate spiral galaxy with visible dark dust lanes. M66 is another intermediate spiral galaxy located approximately 95, light years from Earth. M95 is a barred spiral galaxy that is nearly face-on to our field of view. M96 is another intermediate spiral galaxy.
M is an elliptical galaxy that is known to have a supermassive black hole at its center. Other notable deep-sky objects include an enormous cloud of hydrogen and helium known as the Leo Ring, a spiral galaxy called the Hamburger Galaxy NGC , and a number of other dim galaxies that can only be seen with large telescopes.
Stars can be complex and confusing, but learning about the layers of stars is a lot of fun! Other neighbouring star constellations include Crater, Lynx and Ursa Major. The constellation is one of the largest in the sky. It covers just under square degrees and there are only 12 constellations bigger than Leo.
If you are just starting out as a stargazer or want to look for Leo as a one-off event, the good news is that lots of things are in your favour. The size of this constellation along with its many bright stars will help new stargazers find Leo from the UK much easier than many other constellations.
Leo is best visible in the UK in April and it is recommended to look for the lion around 9pm with low levels of light pollution. You will also need a clear night.
For the best chances of success, head out of big cities or towns and get into the wilderness. The UK has some great spots which are perfect for stargazing, and for searching sparkling lions by night. The two brightest stars in the Leo constellation are relatively close to us compared to many other stars within famous constellations.
Regulus is around 77 light years away from Earth, while Denebola is an estimated 36 light years away. These are incredible distances, but some stars in zodiac constellations are well over light years away.
It is useful to know that constellation stars are not always close to each other. They may seem like they sit at close distances when we peer up from our planet, but some are closer than others. Sometimes, we are closer to one star in a constellation than that star is close to other stars in the same constellation.
That is why there is no single answer when asking for the distance to Leo from Earth. Did you roar? We heard you.
