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 Mrkos at Kleť 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 lightcurve of Aldrin was obtained from photometric observations made at the U.S. Palomar Transient Factory in September 2013. The lightcurve gave a rotation period of 5.9944± 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]
