Best of AOP - Solar System


The Big One. About twelve times the diameter of Earth, Jupiter is the most massive planet in the solar system. Its atmosphere (and it has a lot of atmosphere) is mostly hydrogen and helium, giving it the chemical composition of a star. If it was a hundred times more massive, it would be a star, and you would live in a binary system!

All of the features you see on Jupiter are clouds and storms. The large oval cloud is the "Great Red Spot." Without the aid of a sensitive detector and contrast enhancing processing the GRS looks like the great pale pathetic pink spot with your eye through a telescope (in another words, it is a subtle feature). However, don't let this description deter you from appreciating the magnitude of this Jovian hurricane- it is several times the size of the Earth!

Jupiter orbits the Sun five times further out than Earth, and it is one of the brightest objects in the night sky.
