Scientists think Triton is a Kuiper Belt Object captured by Neptune's gravity millions of years ago. Millions of years from now, Triton will come close enough for gravitational forces to break it apart – possibly forming a ring around Neptune bright enough for Lassell to have seen with his telescope. Dutch-American astronomer Gerard Kuiper (for whom the Kuiper Belt was named) found Neptune's third-largest moon, Nereid, in 1949.

Proteus orbits Neptune about every 27 hours. Like our own moon, Triton is locked in synchronous rotation with Neptune―one side faces the planet at all times.

Overview Proteus is one of the largest of Neptune's known moons, although it is not as big as Triton. Our scientists and far-ranging robots explore the wild frontiers of our solar system. Neptune's orbit was the farthest out, and its gravity bent the paths of countless icy bodies inward toward the other giants. As Uranus and Neptune drifted farther outward, they passed through the dense disk of small, icy bodies left over after the giant planets formed. The moon has an odd box-like shape and if it had just a little more mass it would be able to transform into a sphere.

It shares many similarities with Pluto, the best known world of the Kuiper Belt. He missed Proteus, the second-largest because it's too dark and too close to Neptune for telescopes of that era. As these planets grew in the early solar system, they were able to capture smaller objects with their large gravitational fields. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids. uq5w zvw 6zhhph mft tinn 3hvm fmcpyy 8zlj ople 3whh4j
