Iota Leonis is a triple star system, located at around 79 light-years away from us. Tau Leonis is the 31 st brightest star in Leo, having an apparent magnitude of 5.
This star is located at around light-years away from us. Tau Leonis is a G-type giant star that is currently expanding its outer layers. Rasalas, designated as Mu Leonis, is the 13 th brightest star in Leo, having an apparent magnitude of 3. Rasalas is an evolved K-type giant star with strong absorption lines of cyanogen and calcium in its spectrum.
In , a planet was confirmed to orbit Rasalas. This companion appears to be 2. Chertan is an A-type main-sequence star, however, its spectrum shows strong absorption lines of metals, marking it as a chemically peculiar Am star. Chertan is also surrounded by a circumstellar disk of gas and dust that stretches across space for around 36 AU. The temperatures on Chertan are also greater, 9, K.
Wolf is a red dwarf star located at only 7. This star also hosts 2 exoplanets. It is a faint star, having an apparent magnitude of Wolf is among the nearest stars to the Sun, the fifth closest. This star is also much cooler than our Sun, with its temperatures reaching only 2, K. The two exoplanets discovered in are both more massive than Earth.
R Leonis is a red giant Mira-type variable star located at around light-years away from us. The apparent magnitude of this star varies between 4. A planet is theorized to orbit R Leonis, which would have less than two Earth masses, however, it is still unconfirmed. R Leonis is 5, times brighter than our Sun, however, its surface temperatures reach only at around 2, K, less than our Sun.
Gliese is a red dwarf star located at around 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. 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. Recent exoplanet discoveries in the constellation Leo show a cornucopia of strange words, as well as at least one planet that is potentially habitable.
Back in , astronomers found a planet orbiting a dying red giant star known as HD It is about 1, light-years away from Earth. If you draw a line between these stars, it points towards the North Star, and the constellation of Leo. The best season to see Leo Constellation is in the spring equinox. You can identify it in the Northern Hemisphere in May or April. This is when the constellation is the most prominent in the night sky. Leo Constellation can be seen from both hemispheres from January to June.
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 star exhibits variations in brightness over a period of days. Consequently, its apparent magnitude varies too, ranging from 1.
It has a visual magnitude varying from 4. Mira variables are pulsating variable stars that are in the late stage of evolution, very red in colour, and with pulsation periods longer than days. They eventually expel their outer envelopes to form planetary nebulae and become white dwarfs within a few million years. R Leonis is approximately light years distant from the solar system. When it is at its brightest, it can be seen without binoculars, and when it is on the dimmest end of the spectrum, one needs at least a 7 cm telescope to see the star.
R Leonis has a radius times solar. Messier 65 is an intermediate spiral galaxy in Leo. The galaxy was discovered by Charles Messier in Most of the stars in the galaxy are old. Messier 66 is an intermediate spiral galaxy in Leo. Charles Messier discovered it in The galaxy has a visual magnitude of 8.
M66 is approximately 95, light years across and notable for its dust lanes and bright star clusters. NGC is an unbarred spiral galaxy approximately 35 million light years distant from the solar system. It was discovered by William Herschel in The galaxy is notable for having a long tidal tail spanning about , light years, and a broad, obscuring dust band along the outer edge of its spiral arms.
Messier 95 is a barred spiral galaxy in Leo. The central region of M95 has a ring-shaped starburst region around the core with a diameter spanning about 2, light years. The galaxy Messier 95 stands boldly face-on, offering an ideal view of its spiral structure.
The spiral arms form an almost perfect circle around the galactic centre before they spread out, creating a mane-like effect of which any lion would be proud. Another, perhaps even more striking, feature of Messier 95 is its blazing golden core. This phenomenon occurs mostly in barred spiral galaxies such as Messier 95 and our home, the Milky Way.

M95 belongs to the M96 Group of galaxies, which also includes M96 and M, and also at least nine other galaxies. Messier 96 is another intermediate spiral galaxy in Leo constellation. M96 is the brightest galaxy in the M96 Group.
It is of about the same mass and size as the Milky Way. The galaxy resembles a giant maelstrom of glowing gas, rippled with dark dust that swirls inwards towards the nucleus. Messier 96 is a very asymmetric galaxy; its dust and gas is unevenly spread throughout its weak spiral arms, and its core is not exactly at the galactic centre. Its arms are also asymmetrical, thought to have been influenced by the gravitational pull of other galaxies within the same group as Messier This group, named the M96 Group, also includes the bright galaxies Messier and Messier 95, as well as a number of smaller and fainter galaxies.
It is the nearest group containing both bright spirals and a bright elliptical galaxy Messier The galaxy is classified as a double-barred spiral with a small inner bulge through the centre along with an outer bulge. Messier is an elliptical galaxy in Leo.
The galaxy is known to have a supermassive black hole at its centre. Astronomers have concluded that these stars are zooming around a supermassive black hole with an estimated mass of million Suns!
This black hole releases huge amounts of energy as it consumes matter falling into it and causing the centre to shine far brighter than its surroundings. This system is known as an active galactic nucleus. The Leo Ring is an enormous primordial cloud of hydrogen and helium found in orbit of two galaxies in the Leo constellation. The cloud was discovered by radio astronomers in NGC is a spiral galaxy in Leo.
