The Great Red Spot Has Been Around For A Long Time

A well-known feature of Jupiter is the Great Red Spot, it is one of the interesting facts about Jupiter. The diameter and height of this persistent anticyclonic storm, which is south of the equator, range from 24,000 km to 12–14,000 km. As a result, it has enough space to hold two or three planets with a diameter comparable to Earth's. And because it was first discovered in the 17th century, the location has existed for at least 350 years.

In the year 1665, Italian astronomer Giovanni Cassini made the first observation of the Great Red Spot. Astronomers theorized that it was a storm during the 20th century, one that was caused by Jupiter's turbulent and rapidly moving atmosphere. The Voyager 1 mission, which studied the Giant Red Spot up close during its flyby of the planet in March 1979, supported these theories.

However, it seems to have been becoming smaller ever since. The size was believed to be 40,000 km in the 17th century based on Cassini's measurements, which is near twice as big as it is today. Although they are unsure about when or if it will ever completely vanish, astronomers are reasonably confident that another one will appear someplace else on the planet.
