2069 Hubble is a dark-colored main belt asteroid.[1] It was discovered by the Indiana Asteroid Program at Goethe Link Observatory on March 29, 1955.[1] The asteroid was named after the famous American astronomer Edwin Hubble.[1]

Photometric measurements of the asteroid made in 2005 at the Palmer Divide Observatory showed an unusual tri-modal light curve with a period of 32.52 ± 0.02 hours and a brightness variation of 0.10 ± 0.02 in magnitude.[2]
