The planet with the hottest surface is Venus.

The planet with the hottest core is probably Jupiter.


Mercury is closer to the sun than Venus, so receives more heat from the sun per square metre of surface, but Venus has a runaway greenhouse effect, resulting in a higher surface temperature, about #735# Kelvin.

Jupiter probably has the hottest core at an estimated #20,000# Kelvin or more.
