28 Νοε 2008 · Learn how strong the gravity is on Neptune, a gas planet with 17 times the mass of Earth but 3.8 times the diameter. Find out how you would feel if you could walk on Neptune and compare it to other planets.
Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth. Compared to its fellow ice giant Uranus, Neptune is slightly more massive, but denser and smaller.
3 Οκτ 2024 · Compare Neptune and Earth's bulk parameters, orbital parameters, and observational parameters. Find Neptune's gravity, mass, volume, radius, density, and more.
Learn about Neptune, the eighth and most distant planet in our solar system, from NASA Science. Find out its size, distance, orbit, moons, rings, formation, structure, surface, atmosphere, and magnetosphere, but not its gravity.
The surface gravity on Neptune is about 110% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 110 pounds on Neptune (assuming you could find someplace to, well, stand).
How big is Neptune? How far is it from the Sun? Use this tool to compare Neptune to Earth, and other planets. Read More
2 ημέρες πριν · Neptune is the only giant planet that is not visible without a telescope. It has an apparent magnitude of 7.8 and is approximately one-fifth as bright as the faintest stars visible to the unaided eye. Hence, there were no observations of Neptune before the use of telescopes.
