Trajectory of 2004 FH in the Earth–Moon system Goldstone radar images of asteroid 2007 PA 8 's Earth flyby in 2012. This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation.
The first few thousand minor planets have all been named, with the near-Earth asteroid (4596) 1981 QB currently being the lowest-numbered unnamed minor planet. [2] The first 3 pages in the below table contain 1,000 named entries each.
The choice for this name may have been inspired by the asteroid's provisional designation, containing the letters "DN". DMP · 667: 668 Dora: 1908 DO: Dora, a friend of the wife of astronomer August Kopff, who discovered this asteroid. The name may have been inspired by the asteroid's provisional designation, containing the letters "DO". DMP · 668
An asteroid for which there is some possibility of a collision with Earth at a future date and which is above a certain size is classified as a potentially hazardous asteroid (PHA). Specifically, an asteroid is a PHA if its Earth minimum orbital intersection distance (MOID) is <0.05 AU and its absolute magnitude is 22 or brighter. [2]
Inner asteroid belt, inside of the strong Kirkwood gap at 2.50 AU due to the 3:1 Jupiter orbital resonance. The largest member is 4 Vesta . It apparently also includes a group called the main-belt I asteroids which have a semi-major axis between 2.3 AU and 2.5 AU and an inclination of less than 18°.
The 2000 recovery of 719 Albert, which had been lost for nearly 89 years, eliminated the last numbered lost asteroid. [9] Only after a number is assigned is the minor planet eligible to receive a name. Usually the discoverer has up to 10 years to pick a name; many minor planets now remain unnamed.
