Neptune has the strongest winds of any planet in the solar system with the uppermost atmosphere reaching minus 218 degree celsius. However, the interior is very hot and this helps cause the strong winds. It is also not uncommon for Neptune to experience violent hurricanes. Neptune has 13 known moons and the largest Triton was discovered just 17 days after the planet was discovered itself. Triton is measured as the coldest object in the solar system with temperatures at minus 235 degree celsius.
