Distribution of 5120 asteroids as of 2007 August 26

Distribution of 5120 asteroids detected by AKARI as of 2007 August 26. The distribution of asteroids is not uniform, but is split into various groups due to the motion of Jupiter. There are a number of groups of asteroids; the main belt asteroids that shows the most dense population between Mars's and Jupiter's orbit; the Jovian Trojans that swarm around the Jupiter's orbit; the near Earth asteroids that have the possibilities to come close to the Earth's orbit. Asteroids of each group have different properties and are thought to have different origins. The near Earth asteroids tend to be detected close to Earth, since AKARI observed in the direction perpendicular to the Sun-Earth line.
