A Mercury crosser or Mercury grazer is an asteroid whose orbit crosses that of Mercury. The Mercury crossers proper have aphelia outside Mercury's and perihelia inside Mercury's, 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 known inner grazers.
