List of Mercury-crossing minor planets


List of Mercury-crossing minor planets

A Mercury crosser is an asteroid whose orbit crosses that of Mercury. The Mercury crossers proper have aphelia outside Mercury's (0.4667 AU) and perihelia inside Mercury's (0.3075 AU), while those listed here as outer grazers have perihelia within Mercury's aphelion but not within its perihelion. All have semi-major axes larger than Mercury's, and hence there are no inner grazers.

Mercury grazers

All Mercury grazers have semi-major axes larger than Mercury's (0.3871 AU), and hence are outer grazers, i.e. have perihelia within Mercury's aphelion (0.4667 AU) but not within its perihelion (0.3075 AU). There are currently 391 Mercury grazers known.[2] Values have been rounded to three decimals.
