8013 Gordonmoore

Orbit and classification

Gordonmoore orbits the Sun at a distance of 1.3–3.1 AU once every 3 years and 3 months (1,192 days). Its orbit has an eccentricity of 0.43 and an inclination of 8° with respect to the ecliptic.

It has a minimum orbit intersection distance with Earth of 0.2472 AU, or 96.3 lunar distance. Due to its eccentric orbit, Gordonmoore is also Mars-crosser. In 2127, the asteroid will pass the Red Planet within 0.02776 AU.

A first precovery was taken at the discovering Palomar Observatory in 1951, extending the body's observation arc by 39 years prior to its official discovery observation.

Physical characteristics

Rotation period

In April 2016, a rotational lightcurve of Gordonmoore was obtained from photometric observations by astronomer Brian Warner at the Palmer Divide Station (716) in Colorado. It gave a rotation period of hours with a brightness variation of 0.25 magnitude. Lightcurve analysis also gave an alternative period solution of 4.19 hours with an amplitude of 0.25 magnitude. (). The results supersede a previous observations made at the Hoher List Observatory in Germany, that gave a shorter period of 6 hours ().

Diameter and albedo

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 1.04 kilometers with an absolute magnitude of 17.26. In the 1990s, Tom Gehrels estimated the body's diameter to be 2.3 kilometers, assuming an albedo of 0.15.

Naming

This minor planet was named in honour of American entrepreneur and billionaire, Gordon Moore (1929–2023), co-founder of Intel, known for his revolutionary vision of the future of computers, and author of Moore's law. As a philanthropist, Moore has supported research and education all his life. The official naming citation was published by the Minor Planet Center on 26 May 2002 (M.P.C. 45747).
