Crater II

Crater II is a dwarf spheroidal galaxy that orbits the Milky Way as a satellite galaxy. Discovered in 2016 using data from the Dark Energy Survey, it is in the constellation Crater, approximately 380,000 light-years away from Earth. As an ultra-faint galaxy, it possesses very low luminosity, making it challenging to detect. With an estimated radius of about 65 parsecs and an absolute magnitude around -2.9, it is among the faintest and smallest galaxies known within the Milky Way's satellite system. Its stellar population primarily comprises old stars with low metallicity, suggesting that its formation occurred in the early universe.
