WebScience. In the ideal case, the lowest possible orbit would be just above the surface of the earth. The problem is that if there are mass concentrations, the orbit gets thrown off course and is not stable. A more intresting case is the moon, which is has a spherical shape and no atmosphere. The moon has a number of large mass concentrations ... A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25.
