What is Neptune’s biggest moon?
Triton is the largest of Neptune’s 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet’s rotation―a retrograde orbit.
What are Neptune’s 14 moons?
Moving from closest to Neptune to furthest out, their names are Naiad, Thalassa, Despina, Galatea, Larissa, S/2004 N1 (which has yet to receive an official name), Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, and Neso. The first moon to be discovered was Triton, which is also the largest one.
What is Neptune’s smallest moon called?
Astronomers have given a name — “Hippocamp” — to the most recently discovered moon of Neptune, which also formerly went by S/2004 N1. They’ve figured out how big the satellite is as well, and teased out some interesting details about its past, a new study reports.
Is Triton bigger than our moon?
Little was known about Triton until 1989, when the U.S. Voyager 2 probe flew within 40,000 km (24,800 miles) of it. As measured by Voyager, Triton is about 2,706 km (1,681 miles) across, which is nearly the diameter of Earth’s Moon.

Can we live on Triton moon?
It is very cold on Triton, about -300 degrees. There is almost no atmosphere, but what there is is like Saturn’s moon Titan because there is Nitrogen. Nitrogen is one of the waste products left behind by life forms. Unfortunately Triton is inside the magnetosphere of Neptune, which is very harmful to life.
Is Triton bigger than Pluto?
Triton is only slightly larger than Pluto. Both worlds have similar surface materials, such as nitrogen, methane and carbon monoxide. Their diameters, masses and densities are amazingly similar. Both Triton and Pluto may also have originated within the Kuiper Belt.
Why does Neptune’s moon Triton orbit backwards?
The Backwards Moon
Triton orbits Neptune in what is known as a retrograde orbit. This means that it orbits Neptune a direction opposite the planet’s rotation. … Others think that Triton may have been formed elsewhere and then captured by Neptune’s gravity.
Does Earth have 3 moons?

This is because a phenomenon called libration causes the moon’s viewing angle, relative to Earth, to change slightly over its orbit. Lunar libration is due to the fact that the moon’s orbit around Earth isn’t a perfect circle. … The moon looks round, but it isn’t.
