Explanation: Vesta is a huge rock 500 kilometers across that orbits out past Mars (http://www.seds.org/nineplanets/nineplanets/mars.html). In 1997, the above map (http://oposite.stsci.edu/pubinfo/PR/97/27/9727c.html) of Vesta (http://en.wikipedia.org/wiki/4_Vesta) created using the Hubble Space Telescope (http://antwrp.gsfc.nasa.gov/apod/ap970306.html) was released showing a rugged surface highlighted by a single crater spanning nearly the entire length of the asteroid (http://en.wikipedia.org/wiki/Asteroid). The large crater dominates the lower part of the above false-color conglomerate image (http://hubblesite.org/newscenter/newsdesk/archive/releases/1997/27/image/e): blue indicates low terrain, while red indicates raised terrain. Evidence indicates that Vesta (http://oposite.stsci.edu/pubinfo/background-text/vesta.txt) underwent a tremendous splintering collision (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1996A%26A...316..248M) about a billion years ago. In October 1960, a small chunk of this rock believed to have originated on Vesta (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2001M%26PS...36..501D) fell to Earth (http://antwrp.gsfc.nasa.gov/apod/ap050102.html) and was recovered in Australia (https://www.cia.gov/cia/publications/factbook/geos/as.html). Vesta is considered by some to be a candidate for reclassification into a planet (http://www.iau2006.org/mirror/www.iau.org/iau0601/iau0601_release.html).
