Triton was discovered on Oct. 10, 1846 by British astronomer William Lassell, just 17 days after Neptune itself was discovered.
Triton is the largest of Neptune's 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet's rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by Neptune's gravity millions of years ago. It shares many similarities with Pluto, the best know...
Triton is named after the son of Poseidon (the Greek god comparable to the Roman Neptune). Until the discovery of the second moon Nereid in 1949, Triton was commonly known as simply "the satellite of Neptune."
May 21, 2024 · It is widely thought that Triton is a captured Kuiper belt object. The Kuiper belt is a second asteroid belt out beyond the orbit of Neptune. Pluto and Eris are examples of Kuiper belt objects. On 25 August 1989, the Voyager 2 spacecraft made a fly-by of the Neptunian system and took high-resolution pictures of Triton.
Feb 29, 2024 · The Kuiper Belt is a population of objects located beyond the Neptunian orbit (Morbidelli & Levison, 2014), with its existence predicted by astronomers Edgeworth and Kuiper in 1943 and 1951 respectively, sometimes also referred to as the Edgeworth-Kuiper Belt.
Jun 6, 2011 · The current thinking is that Triton was not a rock but probably a Kuiper Belt object that was somehow pushed Neptune’s way.
Nov 11, 2024 · Kuiper belt, flat ring of icy small bodies that revolve around the Sun beyond the orbit of the planet Neptune. It comprises hundreds of millions of objects whose orbits lie close to the plane of the solar system. The Kuiper belt is thought to be the source of most of the observed short-period comets.
