6470 Aldrin, provisional designation 1982 RO1, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 3 kilometers in diameter.

The asteroid was discovered by Czech astronomer Antonín MrkosatKleť Observatory on 14 September 1982.[6] It was named for American astronaut Buzz Aldrin.[2]

Orbit and classification

[edit]

Aldrin is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,253 days). Its orbit has an eccentricity of 0.15 and an inclination of 3° with respect to the ecliptic.[1] The asteroid's observation arc begins in 1982, as no precoveries were taken and no prior identifications were made.[6]

Physical characteristics

[edit]

A rotational lightcurveofAldrin was obtained from photometric observations made at the U.S. Palomar Transient Factory in September 2013. The lightcurve gave a rotation periodof5.9944±0.0014 hours with a brightness variation of 0.82 in magnitude (U=2).[4]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 3.0 kilometers with an absolute magnitude of 14.78.[3]

Naming

[edit]

This minor planet was named for American astronaut Buzz Aldrin (born 1930), on the occasion of the 30th anniversary of the Apollo 11 mission.[2]

He was one of the first two humans to land on the Moon, and the second person to walk on it, following Neil Armstrong, after whom the asteroid 6469 Armstrong is named. Its name was suggested by Czech astronomers Jana Tichá, Miloš Tichý and Zdeněk Moravec, who observed the asteroid during its 1995-opposition, shortly before being numbered.[2] The official naming citation was published by the Minor Planet Center on 4 May 1999 (M.P.C. 34623).[7]
