A Mercury crosser is an asteroid

Asteroid

Asteroids are a class of small Solar System bodies in orbit around the Sun. They have also been called planetoids, especially the larger ones...

whose orbit

Orbit

In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet around the center of a star system, such as the Solar System...

crosses that of Mercury

Mercury (planet)

Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 Earth days. The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt. It completes three rotations about its axis for every two orbits...

. The Mercury crossers proper have aphelia

An apsis , plural apsides , is the point of greatest or least distance of a body from one of the foci of its elliptical orbit. In modern celestial mechanics this focus is also the center of attraction, which is usually the center of mass of the system...

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 crossers

Mercury crossers proper have aphelia

Apsis

outside Mercury's (0.4667 AU) and perihelia inside Mercury's (0.3075 AU). There are currently 182 Mercury crossers known. Values have been rounded to three decimals.

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. Values have been rounded to three decimals.
