意味（1）

(astronomy) Of a meteoroid: entering the Earth's atmosphere and leaving into space again.

A computer program especially suited to the simulation of Earth-grazing meteors has been listed and described in the Astronomical Computing department of Sky & Telescope. The program allows for the curvature of the Earth; it is therefore possible to follow an Earth-grazing meteor as it descends, reaches perigee, and then ascends back into space.

意味（2）

(astronomy) Approaching the Earth closely.

How many [orbital periods] are there in a year for an Earth-grazing satellite? Since the time of Sputnik (October 4, 1957), it has been familiar that a satellite in a low orbit revolves about the Earth in about 90 minutes. That period would be 84 minutes for the hypothetical Earth-grazing satellite.
