Neptune is similar in size and composition to Uranus but slightly denser and more massive. Winds in its atmosphere reach about 2,000 km/h.

It was the first planet found by mathematical prediction: irregularities in Uranus’s motion led Urbain Le Verrier to calculate its position, and Johann Galle found it in 1846. Its largest moon, Triton, orbits backwards and is probably a captured Kuiper belt object.
