Neptune is big, it’s blue, and it is a planet that can tear you apart if you happen to drop into one of its massive, ...

Second, Triton is one of the irregular moons. It orbits backward relative to Neptune's spin, and its orbit is inclined at a stunning 67 degrees — almost perpendicular to its parent planet.

And Triton is not the only outlier at Neptune. Nereid, one of the planet's outermost moons and the third largest, has one of the most stretched out, or eccentric, orbits of any moon in our solar ...

Triton was discovered in 1846 by the British astronomer William Lassell, but much about Neptune’s largest moon still remains a mystery.A flyby by NASA's Voyager 2 spacecraft in 1989 offered a ...

For years, scientists have suspected that Triton wasn't part of Neptune's original collection of moons. The massive moon has a backward orbit, and makes up over 99 percent of all the mass orbiting ...

Triton, which is about 1,680 miles (2,700 kilometers) wide, has a unique property among large solar system moons: a retrograde orbit. [Video: Fly By Neptune's Freezing Moon Triton] ...

Of Neptune's 13 moons, Triton is by far the largest, and, at 2700 kilometres in diameter (or three quarters the Earth's Moon), is the seventh largest moon in the whole Solar System.

Neptune's original family of satellites may have been destroyed when its largest moon, Triton, entered the picture. New research suggests that the massive moon may have tossed some of the original ...

Though Triton is a moon and Pluto is a dwarf planet, the pair may share common origins. In Greek mythology, Triton was the son of the sea god Poseidon, known as Neptune by the Romans.

Neptune's largest moon, Triton, was originally a member of a duo orbiting the Sun and was kidnapped in a close encounter with Neptune, a new model suggests.

This color photo of Neptune's largest moon Triton was obtained by NASA's Voyager 2 probe on Aug. 24, 1989, from 330,000 miles away. The resolution is about 6.2 miles, sufficient to begin to show ...
