In Depth | Proteus ? NASA Solar System Exploration
15 Mar 2026 at 6:24pm
Overview Proteus is one of the largest of Neptune's known moons, although it is not as big as Triton. 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. Proteus orbits Neptune about every 27 hours.

Dutch-American astronomer Gerard Kuiper (for whom the Kuiper Belt was named) found Neptune's third-largest moon, Nereid, in 1949. He missed Proteus, the second-largest because it's too dark and too close to Neptune for telescopes of that era.

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.

In 1943, astronomer Kenneth Edgeworth hypothesized that many small, icy bodies exist in a disc in the region beyond Neptune, having condensed from widely spaced ancient material, and that from time to time one of them visits the inner solar system.

Jupiter is the fifth planet from the Sun, and the largest in the solar system ? more than twice as massive as the other planets combined.
