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 ...

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.

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 ...

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 ...

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 ...

Triton, unique among all the large moons in the solar system because it orbits Neptune in a direction opposite to the planet's rotation, may have abandoned an earlier partner to arrive in its ...

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 largest moon, Triton, passed in front of a distant star in a rare celestial event known as an occultation — and the European Space Agency's Gaia spacecraft revealed new clues about the ...

Triton was discovered in 1846 by the British astronomer William Lassell, but much about Neptune’s largest moon still remains a mystery.

Neptune’s large moon Triton may have abandoned an earlier partner to arrive in its unusual orbit around Neptune. Triton is unique among all the large moons in the solar system because it orbits ...

NASA has proposed a mission to explore Neptune’s mysterious and “weird” moon Triton, the coldest known object in the solar system. In a statement posted to its website, the space agency said ...
