Main-belt asteroid
74 Galatea is a large C-type main-belt asteroid . Its carbonaceous surface is very dark in color with an albedo of just 0.034.[ 7] comet discoverer Ernst Tempel on August 29, 1862, in Marseilles , France . It was his third asteroid discovery. It is named after one of the two Galateas in Greek mythology . A stellar occultation by Galatea was observed on September 8, 1987. The name Galatea has also been given to one of Neptune 's satellites .
Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico gave a light curve with a period of 17.270 ± 0.002 hours and a brightness variation of 0.08 ± 0.01 in magnitude . The curve displays four minima and four maxima.[ 4] [ 7]
