Learning Point

  • The Great Red Spot has been seen in various forms on the surface of Jupiter since the early days of telescopes, with the storm slowly changing over the course of the past two hundred years of observations. It is immense, bigger than Earth, but isn’t a permanent feature of Jupiter.

Fun Facts

  • The Great Red Spot is over 1.3 times the size of Earth, and is a giant hurricane-like storm.
  • It takes 4 and a half days to rotate once.
  • The tops of the clouds of this storm reach about 5 miles higher than the surrounding clouds.
  • At one point it was stretched out three times as wide as Earth, but is now becoming more circular.
  • It was first seen in 1665, but probably existed before then, and may have been an earlier version of the storm. It is not clear if the storm we see today has been continuous since 1665 or not.
