Aten asteroid
was discovered by LINEAR in January 2000 and was soon after located by DANEOPS on Palomar plates from 10 February 1997. This allowed a reasonably precise orbit determination, and as a result it was spotted again on 27 February 2001 and 21 January 2002. When it was discovered, it beat 1995 CR's record for both asteroid with the smallest perihelion and for Aten asteroid with the highest eccentricity.
