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 ...

An enhanced view of Neptune's largest moon, Triton. Sometimes, astronomy is like a forensic investigation: We can't just rerun the past, so we have to study clues to figure out what happened. And ...

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

Neptune's original family of satellites may have been destroyed when its largest moon, Triton, entered the picture. For years, scientists have suspected that Triton wasn't part of Neptune's ...

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 ...

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 the ...

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 ...

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.

Triton is also an “irregular” satellite that has an inclined, circular orbit around Neptune. It is highly unlikely that the moon formed in such a configuration and was probably captured from elsewhere ...
