It is suspected of being an inner fragment of the differentiated asteroid 4 Vesta.2011-01-06 A look into Vesta's interior Max Planck Society http://www.mpg.de/877913/Pressrelease20110106 2011-01-07 https://web.archive.org/web/20110113015844/http://www.mpg.de/877913/Pressrelease20110106 13 January 2011 live Given an absolute magnitude (H) of 17.9, and that the albedo is unknown, this NEO could vary from 500 to 1500 meters in diameter. 1999 TA 10 was discovered by LINEAR at Lincoln Laboratory ETS on 5 October 1999 at apparent magnitude 17.7, when it was only 0.39 AU from Earth.2010-11-08 last obs JPL Close-Approach Data: 237442 (1999 TA10) https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=1999TA10;cad=1#cad 2011-01-12 In 2010, it came within 0.3 AU of Earth. During the 2010 close approach, NASA Infrared Telescope Facility (NASA IRTF) studies suggested that 1999 TA 10 originated from the interior of Vesta. The next close approach was in 2023. In 2086, it will come within 0.017 AU km mi on on of Mars. See also Vestoid V-type asteroid References External links 237442 237442 1999TA10 237442 237442 (237442) 1999 TA 10 237442 237442 19991005
