How big is Jupiter?
Jupiter has an equatorial diameter of 141,700 km compared to Earth's 12,800 km. This means that Jupiter is 11 times the diameter of the Earth, and 1,300 times its volume. This is about like comparing a basketball to a ping pong ball.
Compared to the Sun, Jupiter is about 0.001 its mass, and is about 1/50 its diameter. If the Sun were a basketball, Jupiter would be about the size of a pea.
