Which planet has the longest running storm?

Question

which planet has the longest running storm? i was thinking either jupiter or neptune.

Answer 1

It's impossible to say. The only reason people quote Jupiter is because 400 years ago Galileo built the first telescope, pointed it a Jupiter and saw the spot. For all we know, it's been there for 4 billion years, but no one saw it.

Same with Neptune and Uranus. They both have massive storms that have been raging since we first looked at them with Voyager. They could have been going on for billions of years too.

On Earth, storms are created through convective heat transfer and die when they crash on land. On the outer planets, storms are fed from the internal heat of formation - and endless supply of energy. Plus, these planets are all gas - nothing to slow the storm down. So there's nothing to stop them. They can go on forever.

Answer 2

Indeed, it is Jupiter, the fifth planet from the sun. Jupiter the largest planet in the system, has the most moons and the longest running storm (The Great Red Spot). Jupiter is eleven times wider than the Earth and over twice the weight of all the other planets put together.

Answer 3

The so-called 'Big Red Spot' on Jupiter is the longest running storm we know of. It's been going on for at least 500 years when it was first observed, but it's probably been there even longer.
