SEGUE ONE
Segue 1 is a dwarf spheroidal galaxy or globular cluster situated in the Leo constellation and discovered in 2006 by the Sloan Digital Sky Survey. It is located at a distance of about 23 kpc (about 75,000 light years) from the Sun and moves away from the Sun with a velocity of about 206 km/s. Segue 1 has a noticeably elongated (ratio of axes ~ 2:1) shape with a half-light radius of about 30 pc. This elongation may be caused by tidal forces from the Milky Way galaxy if Segue 1 is being disrupted now.
The name is due to the fact that it was found by the SEGUE program, the Sloan Extension for Galactic Understanding and Exploration.
