The Carina Dwarf Spheroidal is a dwarf galaxy in the Carina constellation. It was discovered in 1977 with the UK Schmidt Telescope.[citation needed] The Carina Dwarf is receding from the Milky Way at 230 km/s and is a satellite galaxy to the Milky Way. The galaxy may also be referred to as E206-G220 or PGC 19441. It appears to have formed several billion years after the formation of the other satellite galaxies of the Milky Way as its older stars are younger than 7 billion years,[citation needed] making it a relatively youthful galaxy compared to the Milky Way, which is estimated to have formed 13.6 billion years ago, or nearly as old as the Universe itself. It probably has a complex star formation history, with two possible distinct bursts of star formation.[citation needed] It is also being tidally disrupted by the Milky Way galaxy.[citation needed]
