6470 Aldrin, provisional designation 1982 RO1, is a stony asteroid from the inner regions of the asteroid belt, about 3 kilometers in diameter. It was discovered by Czech astronomer Antonín Mrkos at Kleť Observatory on 14 September 1982.[5]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,253 days). Its orbit shows an eccentricity of 0.15 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of 5.99 hours[4] and an albedo of 0.24, as assumed by the Collaborative Asteroid Lightcurve Link (CALL).[3]
The minor planet was named in honor of Edwin Eugene "Buzz" Aldrin Jr. (b. 1930), U.S. astronaut of Apollo 11 and the second man to set foot on the Moon. In 1966 he made a record 5.5-hour spacewalk in the course of the Gemini 12 mission. In 1969 he joined Armstrong (also see 6469 Armstrong) on the surface of the Moon. This minor planet commemorates the thirtieth anniversary of the first manned lunar-landing mission. Its name was suggested by J. Tichá, M. Tichý and Z. Moravec, who observed this minor planet at its 1995 opposition, just prior to numbering.[2]
