What's the biggest planet in the Solar System and the third-brightest natural object in the night sky?
Answer Jupiter
Jupiter has a long history of stunning astronomers, beginning in 1610 when Galileo Galilei discovered its moons. Jupiter, the fifth planet from the Sun is, by far, the biggest planet in the solar system, with a mass of more than double all the other planets combined. Its stripes and swirls are windy clouds of ammonia, and the famous Great Red Spot is a storm that has raged for centuries.
