4833 Meges (1989 AL2) is a 83 km Jupiter Trojan discovered on January 8, 1989 by American astronomer C. S. Shoemaker at Palomar. It is orbiting at the L4 Lagrange point.[2]
Photometric observations of this asteroid during 1995 were used to build a light curve showing a rotation period of 14.25 ± 0.03 hours with a brightness variation of 0.13 ± 0.01 magnitude.[2]
