Kiso 5639 (also known as LEDA 36252, KUG 1138+327 or the Skyrocket Galaxy) is an irregular dwarf galaxy in the constellation Ursa Major, approximately 85 million light-years from Earth. It has an elongated and flattened shape, with a maximum diameter that extends for approximately 2,700 light years. The new stars are distributed in about ten groups and have a mass corresponding to about one million solar masses. This intense activity also corresponds to the presence of areas in which the matter is rarefied, which were probably formed following a combination of stellar winds and supernovae explosions. The starburst of the galaxy is believed to have occurred around one million years ago.
