2069 Hubble, provisional designation 1955 FT, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 40 kilometers in diameter. It was discovered on 29 March 1955, by the Indiana Asteroid Program at Goethe Link Observatory, United States, and named after American astronomer Edwin Hubble.[2][13]

Orbit

Hubble orbits the Sun in the outer main-belt at a distance of 2.6–3.7 AU once every 5 years and 7 months (2,052 days). Its orbit has an eccentricity of 0.19 and an inclination of 9° with respect to the ecliptic.[1] Its first unused observations, 1953 VN1, was made at Goethe Link in 1953. The body's observation arc begins at NAOJ's Mitaka Campus, 8 days prior to its official discovery observation at Goethe Link.[13]

Physical characteristics

Lightcurve

In January 2005, American astronomer

rotation period of 32.52 hours and a brightness variation of 0.10 in magnitude.[11][a] While not being a slow rotator
, Hubble has a longer than average spin rate, as the vast majority of asteroids rotate between 2.2 and 20 hours once around their axis.

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.024 and 0.0538.[4][5][6][7][8][9][10] The Collaborative Asteroid Lightcurve Link classifies it as a carbonaceous C-type asteroid, derives an albedo of 0.041 and a shorter diameter of 34.44 kilometers with an absolute magnitude of 11.4.[3]
