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] 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).
[13] In January 2005, American astronomer Brian Warner obtained a rotational lightcurve of Hubble from photometric observations taken at his Palmer Divide Observatory in Colorado.
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Hubble measures between 34.53 and 46.92 kilometers in diameter, and its surface has an albedo between 0.024 and 0.0538.
He pioneered in the exploration of the Universe beyond the Milky Way galaxy and established a self-consistent distance scale as far as the 100-inch Hooker Telescope at Mount Wilson Observatory could reach.
