How old is Jupiters red spot?

Answer 1

The red spot is a storm, a hurricane that has been blowing since Galileo first observed it four hundred years ago. We know the storm is therefore at least 400 years old. It may be nearly as old as the solar system itself, about 4.5 billion years. There is no way to know for certain at the present time.

The diameter of the storm varies from about 15,000 miles to around 25,000 miles. You could line our earth across it about three times--it is that large. Its color comes from the variety of elements the storm dredges up from deeper within Jupiter.

Answer 2

It is a large storm cell of swirling winds that has been there ever since observed over 400 years ago. As the slide show shows above different winds in opposite directions seem to create some of these cells in Jupiter's atmosphere.

Answer 3

At least 300 years, but before then nobody could see it.

Answer 4

It is over 400 years old. Galileo first recorded his observations of it in 1610. It is possibly almost as old our our solar system--4.5 billion years. We don't know.

Answer 5

It is over 400 years old. Galileo observed it in 1610. It could be far older yet--possibly almost as old our our solar system itself--about 4.5 billion years.

Answer 6

As far as observational records have existed, the Big Red Spot has been visible for over 300 years
