Usage notes

When referring to astronomical orbits, "in orbit" and "on orbit" have somewhat different meanings. In general, a body is said to be "in orbit" if it is in freefall going around another body; while something happens "on orbit" if it occurs aboard an orbiting spacecraft. Thus one might say, "The space capsule is in orbit, and the astronauts inside are performing experiments on orbit."
