Leo I is a dwarf spheroidal galaxy in the constellation Leo. At about 820,000 light-years distant, it is a member of the Local Group of galaxies and is thought to be one of the most distant satellites of the Milky Way galaxy.

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]

Leo I is a dwarf elliptical galaxy. It belongs to the Local Group and is a distant companion of our Milky Way. According to measurements published on Simbad, this dwarf galaxy is 0.198 Mpc to 0.26 Mpc (645'800 to 848'000 light-years) away and …

2023年4月17日 · The small and faint star-starved dwarf galaxy, Leo IV, is one of more than a dozen ultra-faint dwarf galaxies found lurking around the Milky Way. These galaxies are dominated by dark matter, an invisible substance that makes up the bulk of the universe’s mass.

Leo A (also known as Leo III) is an irregular galaxy that is part of the Local Group. It lies 2.6 million light-years from Earth, and was discovered by Fritz Zwicky in 1942. [4] The estimated mass of this galaxy is (8.0 ± 2.7) × 10 7 solar masses, with …

Leo I is thought to be the most distant of the eleven known small satellite galaxies orbiting our Milky Way Galaxy. Besides the LMC and the SMC, all Milky Way satellite galaxies are small, dim, dwarf spheroidals, including the closest galaxy - the Sagittarius Dwarf. Leo I is more distant than most of them, thought to be about 250 kpc away.

2024年1月1日 · More than 30 of the 59 satellites (any galaxy within 1.4 million light-years) of the Milky Way are dwarf spheroidal galaxies. Leo I lies some 830,000 light-years away, which makes it the Milky...

Leo I Dwarf Spheroidal Galaxy is a dwarf spheroidal galaxy that has a distance from Earth of 690,000.00 light years. It can be found in the constellation of Leo.

Leo I is thought to be the most distant of the eleven known small satellite galaxies orbiting our Milky Way Galaxy. Besides the LMC and the SMC, all Milky Way satellite galaxies are small, dim, dwarf spheroidals, including the closest galaxy - the Sagittarius Dwarf. Leo I is most distant than most of them, thought to be about 250 kpc away.

2016年4月15日 · At first glance, this NASA/ESA Hubble Space Telescope image seems to show an array of different cosmic objects, but the speckling of stars shown here actually forms a single body — a nearby dwarf galaxy known as Leo A. Its few million stars are so sparsely distributed that some distant background galaxies are visible through it.
