NASA's WISE Mission Finds First Trojan Asteroid Sharing Earth's Orbit

More eyes in sky to see what we have not seen before.There has often be a question if anything was out there some 60 degree ahead or behind Earth in its orbit around the Sun.Jupiter, Saturn, yes, Earth, hmmmm.- LRK ------------------------------------------------------------http://en.wikipedia.org/wiki/Trojan_(astronomy)In astronomy, the word trojan refers to a minor planet or natural satellite (moon) that shares an orbit with a larger planet or moon, but does not collide with it because it orbits around one of the two Lagrangian points of stability (Trojan points), L4 andL5, which lie approximately 60° ahead of and behind the larger body. Trojan objects are one type of co-orbital object.Trojan asteroids are Small Solar System Bodies that reside in Trojan points. Trojan moons are moons that reside at Trojan points. Trojan planets are theoretical planets that reside at Trojan points.Saturn has the most known Trojan satellites: Saturn's moon Tethys has two Trojan moons (Telesto and Calypso), and Dionealso has two Trojan moons (Helene and Polydeuces).snip-----------------------------------------------------------Well now we know, something out there.- LRK ------------------------------------------------------------http://www.nasa.gov/mission_pages/WISE/news/wise20110727.htmlNASA's WISE Mission Finds First Trojan Asteroid Sharing Earth's OrbitThis artist's concept illustrates the first known Earth Trojan asteroid, discovered by WISEFull image link.http://www.nasa.gov/mission_pages/WISE/multimedia/gallery/neowise/pia14404.htmlPASADENA, Calif. – Astronomers studying observations taken by NASA's Wide-field ...
