The Carina Dwarf Spheroidal Galaxy is a dwarf galaxy in the Carina constellation. It was discovered in 1977 with the UK Schmidt Telescope by Cannon et al.[5][6] The Carina Dwarf Spheroidal galaxy is a satellite galaxy of the Milky Way and is receding from it at 230 km/s.[1] The diameter of the galaxy is about 1600 light-years, which is 75 times smaller than the Milky Way.[7] Most of the stars in the galaxy formed 7 billion years ago,[8] although it also experienced bursts of star formation about 13 and 3 billion years ago.[9] It is also being tidally disrupted by the Milky Way galaxy.[10]
