According to NASA, about 1000 Earths can fit inside Jupiter. The massive fifth planet is large enough to hold all the planets in the solar system easily.
Jupiter is home to the Great Red Spot, which itself is about three times larger than Earth. Mostly made of helium and hydrogen, Jupiter is considered to be a gas giant, and it is five times further from the sun than Earth. Due to Jupiter's speedy rotation, a typical day on the planet only lasts about 10 hours, and it takes 12 years for this planet to make a complete orbit around the sun.
