Segue 1 [SEP] constellation
Segue 1
Segue 1 is a dwarf spheroidal galaxy or globular cluster situated in the Leo constellation and discovered in 2006 by 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 the velocity of about 206 km/s. Segue 1 has a noticeably elongated (ratio of axes ~ 2:1) shape with the half-light radius of about 30 pc. This elongation may be caused by the tidal forces
Segue 3
Segue 3 is a faint star cluster of the Milky Way galaxy discovered in 2010 in the data obtained by Sloan Digital Sky Survey. It is located in the Pegasus constellation at the distance of about 17 kpc from the Sun and moves away from it with the velocity of .
Segue 3 is extremely faint—its visible absolute magnitude is estimated at −1.2 or even at about , which means that the cluster is only 100 to 250 times brighter than the Sun. Its small radius—of about 2.1
