When was leo constellation discovered

It has an apparent magnitude of The first official confirmed planet around this star is designated as Gliese b, and it has around 21 Earth masses. However, many speculate that a second planet, similar to Earth, or less massive, could be there as well. It is a Mira-type variable star, with its brightness varying from CW Leonis is located at around parsecs away from us, and the astrosphere surrounding this star is 84, AU.

The star is quite bright, being 8, times brighter than our Sun on average, while also reaching a maximum of 11, brighter. When it was discovered, it had the lowest metallicity of any known star.

This star is highly deficient in carbon, nitrogen, oxygen, and completely devoid of lithium. Al Jabbah, designated as Eta Leonis, is a white supergiant star with an apparent magnitude of 3. It is around 2, light-years away from us. NGC has a long tidal tail, of around , light-years.

The Leo Ring is situated at the center of the Leo Group of galaxies. NGC is a field barred spiral galaxy situated at around 30 million light-years away. It was discovered in by William Herschel. This galaxy has a high rate of star formation in its central region. This galaxy is part of the Virgo Supercluster, and it is quite a bright galaxy, having an apparent magnitude of 8.

NGC has , light-years in diameter. The Clowes-Campusano LQG is a large quasar group, consisting of around 34 quasars, and measures around 2 billion light-years across.

It is among the largest known superstructures in the observable universe. This quasar group is located near its larger cousin, the Huge LQG. The quasars are powerup by highly luminous supermassive black holes, spanning a region roughly 2 billion light-years in length, and around 1 billion light-years wide.

When it was discovered, it held the title of the largest and most massive known structure in the universe, until the Hercules Corona Borealis Great Wall was discovered, which stretches for around 10 billion light-years.

There are many conflicting views upon its existence, however, this structure is presumed to stretch from the second to the Third and Fourth galactic quadrants, thus it lies in the northern hemisphere, being part of many constellations. NGC is a lenticular galaxy, and a starburst galaxy, meaning it is still forming new stars at a high rate. A single spiral arm is present in this galaxy, which spirals outwards from its ring.

This galaxy is situated at around NGC is an elliptical galaxy that was discovered in by William Herschel. This galaxy is located at around NGC is an elliptical galaxy that contains one of the largest black holes ever detected, reported to have 9.

This galaxy is the brightest member of the Leo Cluster. NGC is located at around million light-years away from us, and it has an apparent magnitude of The constellation of Leo is associated with two meteor showers , the Leonids, and the January Leonids. The parent body of these meteors appears to be the comet Tempel-Tuttle, which causes significant outbursts every 35 years or so. The normal peak rate is around 10 meteors per hour.

The January Leonids are minor meteor showers, which peaks between January 1 — 7. As of , the Sun appears in the constellation of Leo from August 10 to September Beta Leonis, or Denebola magnitude 2.

The second bright star in Leo, Denebola is 36 light years from Earth. Denebola exhibits a strong infrared excess, which suggests that it might have a circumstellar debris disk of dust in its orbit. Gamma Leonis, also called Algieba magnitude 2. Its primary star is an orange-red K-type giant, while the binary is a yellowish G-type giant. Interesting fact: it has been recently discovered that the primary star, Algieba A hosts a planet.

Zosma, or Delta Leonis magnitude 2. Zosma has a mass and radius around twice that of the Sun. Zosma means 'girdle' in ancient Greek, as it is located on the hip of the lion. Algenubi, or Epsilon Leonis magnitude 2. This star is a yellow giant, located light years from Earth. With a radius 21 times greater than solar, Algenubi is a lot larger and brighter than the Sun: its luminosity is times higher. Zeta Leonis, also called Adhafera magnitude 3.

Adhafera is a white giant, light-years from Earth. The second-brightest, 39 Leonis is located to the south, and the tertiary, 35 Leonis is to the north of the main star. Iota Leonis magnitude 4. Although it is far from the brightest magnitude Wolf is a red dwarf that inherited its name from the German astronomer Max Wolf who first measured its proper motion and listed the star as entry number It has many shiny stars , which makes it one of the most recognizable constellations in the night sky.

It is also designated as Alpha Leonis. Regulus is a blue-white subgiant star. Bacchus was a famous God in mythology, and he was associated with lions. After his death, Hercules put him up in the sky. Leo Constellation occupies an area of square degrees.

It is among the most prominent zodiac constellations. It is made out of four stars, which are grouped into two pairs. This cool blue-colored star is located at the base of the most outstanding asterism in Leo, called The Sickle of Leo. The sickle of Leo has many stars that outline the mane of the Lion.

All of them are very bright galaxies. Leo Constellation looks like a lion. Its name in Latin means lion. In Greek mythology, the constellation of Leo is associated with the Nemean Lion. The brightest star of this trio is Denebola, which means "tail of the lion. The Leo Ring, a cloud of hydrogen and helium gas, orbits of two dwarf galaxies. In Greek mythology, Leo is the Nemean Lion, which terrorized the citizens and had a hide that could not punctured by iron, bronze or stone.

Killing the lion was one of Hercules' 12 labors, which he had to perform as penance for killing his family.

Having broken all of his weapons fighting the man-eating lion, Hercules finally strangled it to death and placed it in the heavens as one of his conquests. Astrology is not a science , but Leo is one of the 13 constellations of the Zodiac. Leo is the fifth sign of the Zodiac and represents those born July 22 to August It is considered a masculine, extroverted sign.
