Leo II (or Leo B) is a dwarf spheroidal galaxy about 690,000 light-years away in the constellation Leo.It is one of 24 known satellite galaxies of the Milky Way. [4] Leo II is thought to have a core radius of 178 ± 13 pc and a tidal radius of 632 ± 32 pc. [5]
The Leo II Groups, or Leo II Cloud, are a series of at least 110 galactic clusters and individual galaxies stretching approximately 30 Mly (9.2 Mpc) ecliptic west of the edge of the Virgo cluster. [ 1 ] [ 2 ] It is located approximately 65 Mly (20 Mpc) to 95 Mly (29 Mpc) from the Solar System , at a right ascension of 10 h 00 m to 11 h 40 m .
The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant (z = 0.022 [1]) in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. [4]
Leo I is located only 12 arc minutes from Regulus, the brightest star in the constellation.For that reason, the galaxy is sometimes called the Regulus Dwarf.Scattered light from the star makes studying the galaxy more difficult, and it was not until the 1990s that it was detected visually.
It is a member of the NGC 3640 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. [4] It lies 2 degrees south of Sigma Leonis and is a member of the Herschel 400 Catalogue. It is condensed and can be spotted with a small telescope from ...
NGC 3681 is an intermediate spiral galaxy in the constellation Leo.The galaxy lies about 90 million light years away from Earth, which means, given its apparent dimensions, that NGC 3681 is approximately 80,000 light years across. [1]
It occupies the center of the Leo II Group of galaxies, forming one of its two brightest members – the other being NGC 3608. [3] It is a member of the NGC 3607 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. [10]
NGC 3684 is a spiral galaxy in the constellation Leo. The galaxy lies about 70 million light years away from Earth, which means, given its apparent dimensions, that NGC 3684 is approximately 80,000 light years across. [1] It was discovered by William Herschel on April 17, 1784. [3] The galaxy features a bar embedded in an elliptical bulge.
