Jupiter is truly a celestial titan. It is equal in volume to 1,300 Earths, with an atmosphere 1,000km thick, below which lies a sea of liquid hydrogen, 20,000km deep. It rotates much faster than Earth, a Jovian day lasting under 10 hours. Such motion fuels immense turbulence in its atmosphere, with wind speeds of almost 1,450km/h producing distinct colour-banding and vast, long-lasting storms such as the great red spot, which is three times the diameter of Earth and visible through binoculars.
