But Phobos won't zip around Mars forever. The doomed moon is spiraling inward at a rate of 1.8 centimeters (seven-tenths of an inch) per year, or 1.8 meters (about 6 feet) each century. Within 50 million years, the moon will either collide with its parent planet or be torn into rubble and scattered as a ring around Mars. … Visa mer In the early 17th century, German astronomer Johannes Kepler proposed that Mars might host two moons, given that it lay between the Earth and Jupiter, which were known to have one and four satellites.

Webb“The international space station orbits the earth at an average distance of approximately 248 miles (400 kilometers)”. Whereas the minimum possible ISS approximate distance is 330 km (205 mi) and a maximum of 410 km (255 mi) from the earth’s surface. Thus it does not have a fixed orbital height.
