06. And, how far is it from Earth to each planet? (A K2S Question)

From The Space Library

All of the planets go around the Sun at different rates; the Earth takes exactly one year, and the dwarf planet Pluto takes 247 years, for example. So the distances from the Earth to any planet are always changing. At its nearest, Mars is just 34 million miles away—140 times as far away as the Moon—but sometimes it is 247 million miles away—roughly 1,000 times as far away as the Moon. Sometimes you have to wait a few years for the right time to send a spacecraft on its way.
