829 Academia is a minor planet orbiting the Sun. The asteroid is roughly 44 km in diameter and has a low albedo.[1] Photometric measurements of the asteroid made in 2005 at the Palmer Divide Observatory showed a light curve with a period of 7.891 ± 0.005 hours and a brightness variation of 0.44 ± 0.02 in magnitude.[2]
