Mercury-crossing asteroid : ウィキペディア英語版 | 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), whereas 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 crossers== Mercury crossers proper have aphelia outside Mercury's (0.4667 AU) and perihelia inside Mercury's (0.3075 AU). , there are 249 Mercury crossers known.〔(List of asteroids with q<0.3075 AU generated by the JPL Small-Body Database Search Engine ) Retrieved 2012-05-30〕 Most values have been rounded to three decimals.
