Neptune has 16 known moons. English merchant and astronomer William Lassell discovered the first and largest of Neptune's moon – Triton – on Oct. 10, 1846, just 17 days after a Berlin observatory discovered Neptune.
Triton is the only large moon in the solar system that circles its planet in a direction opposite to the planet's rotation (a retrograde orbit), which suggests that it may once have been an independent object that Neptune captured.
Neptune is the eighth and farthest planet from the Sun in the Solar System.It is an ice giant.It is the fourth-largest planet in the system. Neptune's mass is 17 times Earth's mass and a little bit more than Uranus' mass. Neptune is denser and smaller than Uranus. Because of its greater mass, Neptune's gravity makes its atmosphere smaller and denser.

Jul 9, 2024 · Structure and Surface. Neptune is encircled by six rings. Neptune, like Uranus, is an ice giant. It’s similar to a gas giant. It is made of a thick soup of water, ammonia, and methane flowing over a solid core about the size of Earth.
Neptune is the eighth planet from the Sun, making it the most distant in the solar system.This gas giant may have formed much closer to the Sun in the early solar system history before migrating out to its current position.
Introduction. Dark, cold, and whipped by supersonic winds, ice giant Neptune is the eighth and most distant planet in our solar system. More than 30 times as far from the Sun as Earth, Neptune is the only planet in our solar system not visible to the naked eye.

Jun 7, 2022 · Neptune. Orbiting the sun at a distance of 2.8 billion miles (4.5 billion kilometers), Neptune is the fourth-largest planet by diameter and third-largest by mass, having a diameter of 30,598 miles (49,244 kilometers). Strangely, it is slightly more massive than Uranus, which is strange given that the mass of the gas giants should increase the closer you get to the sun.
