Jupiter
詳細情報概要 Jupiter
Jupiter is a world of extremes. It's the largest planet in our solar system – if it were a hollow shell, 1,000 Earths could fit inside. It's also the oldest planet, forming from the dust and gases left over from the Sun's formation 4.6 billion years ago. But it has the shortest day in the solar system, taking about 9.9 hours to spin around once on its axis. Jupiter's Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years.
