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.
