In recent years, scientists have discovered hundreds of planets orbiting other stars. Some of these planets are in orbits that are similar to that of earth, which orbits the sun at a distance of , called 1 astronomical unit . Others have extreme orbits that are much different from anything in our solar system. The following problem relates to one of these planets […]
