Planets and Their Sizes

  • Exhibition Text

    • Earth is nearly 13,000 kilometers across. The smallest terrestrial planet, Mercury, has a diameter about 40 percent of that size. Jupiter, the biggest planet, is more than ten times larger than Earth. The maximum possible size for a planet is a few times larger than Jupiter - about the same size as the smallest stars.
