Jupiter
Jupiter is the fifth planet from the Sun and the largest in
the Solar System. It is a gas giant with a mass two and a half
times that of all the other planets in the Solar System
combined, but less than one-thousandth the mass of the Sun.

When the Juno arrived in 2016, it found that Jupiter has a
very diffuse core that mixes into its mantle. A possible cause
is an impact from a planet of about ten Earth masses a few
million years after Jupiter's formation, which would have
disrupted an originally solid Jovian core.

The best known feature of Jupiter is the Great Red Spot, a
persistent anticyclonic storm located 22° south of the
equator. It is known to have existed since at least 1831, and
possibly since 1665.
