639 Latona is a minor planet orbiting the Sun that was discovered by German astronomer Karl Lohnert on July 19, 1907 at Heidelberg.
Photometric observations of this asteroid at Palmer Divide Observatory in Colorado Springs, Colorado during 2007 gave a light curve with a period of 6.139 ± 0.002 hours and a brightness variation of 0.08 ± 0.01 in magnitude. This confirms period measurements of about 6.2 hours reported in 1987 and 2001.
This is a member of the dynamic Eos family of asteroids that most likely formed as the result of a collisional breakup of a parent body.
