Closest point within an orbit (7)

I believe the answer is:

perigee

(Other definitions for perigee that I've seen before include "where orbit's lowest" , "Point where the Moon is closest to the Earth" , "Point of closest approach" , "A low point" , "Point of orbit closest to the earth" .)

I've seen this clue in the Sydney Morning Herald.
