A meteor is a lump of rock in space. When one of these pieces of rock comes close to the earth it may burn up in the atmosphere as a shooting star. An earth grazing meteor is a meteor that has come close enough to our atmosphere that it starts to burn up, but will still pass us by as the angle is too shallow. It will go back out into space having been deflected by earths gravity.
