caption_attribution_description: These low-resolution radar images of asteroid 2007 TU24 were taken over a few hours by the Goldstone Solar System Radar Telescope in California's Mojave Desert. Image resolution is approximately 20-meters per pixel. Next week, the plan is to have a combination of several telescopes provide higher resolution images.
context_page_description: 2007 TU₂₄ is an Apollo near-Earth asteroid that was discovered by the Catalina Sky Survey in Arizona on 11 October 2007. Imaging radar has estimated that it is 250 meters in diameter. The asteroid passed 554,209 kilometer from Earth on 29 January 2008 at 08:33 UTC. At closest approach the asteroid had an apparent magnitude of 10.3 and was about 50 times fainter than the naked eye can see. It required about a 3-inch telescope to be seen.
context_section_description: Goldstone Observatory carried out radar observations on January 23 and 24 January 2008. As of then, the orbit of the asteroid was known with such a high precision that scientists were able to calculate close approaches from the year 67 AD to 2141 AD.  On 29 January 2008 at 08:33 UTC, 2007 TU₂₄ passed by the earth at a nominal distance of 0.0037043 AU (554,160 km; 344,340 mi)  with a relative speed of 9.248 km/s.
  Observations from Arecibo Observatory were taken on 1–4 February. It is a contact binary asteroid.
