Facts
Neptune has the strongest winds in the solar system — up to 2,100 km/h
It was discovered in 1846 by mathematical prediction before it was seen
One year on Neptune equals 165 Earth years
Its moon Triton orbits in the opposite direction to Neptune's rotation
Moons
- Triton — Its retrograde orbit will eventually cause it to be torn apart by Neptune's gravity.
