Neptunes diameter is just over four times that of Venus' diameter, and just under four times that of Earth's diameter.
Both Uranus' and Neptune's diameters are about four times bigger than the Earth's, but Uranus is the closest, with about 50 000 km. The Earth's diameter is 12 756 km, and 4 times bigger than that is 51 024.
Neptune's diameter is about four times larger than Earth's, measuring approximately 49,244 kilometers compared to Earth's diameter of about 12,742 kilometers.
Neptune's diameter is about 30775.2724 miles.
The planet Neptune has a deep, dense atmosphere of gases and liquids, so there is no definitive surface to measure. So the closest approximation of its "diameter" is accurate to about 30 kilometers, and is 49,528 km (30,775 miles), which is almost 4 times as wide as Earth.
Diameter: Neptune's diameter is 49,620 km, while the sun's is 1,377,648 km. So you would be able to fit 27 of them into the diameter of the sun and you would still have room for 70% of another one. Mass: So the sun is 332,946/17=19,585 times more massive than Neptune. Weight: 102.4E24 kg (17.15 times the mass of the earth) Weight of a human on Neptune: 200 lbs on Earth=225 lbs on Neptune
Neptune is a gas giant several times larger than Earth.
The radius of Uranus is roughly 4 times the radius of Earth. However, in volume, it would be around 43=64 times larger than Earth. Hence, There is no planet in our solar system which is four times the size of the Earth.
The sizes of planets vary greatly. For example, Jupiter is about 11 times the diameter of Earth, while Venus is slightly smaller. Mercury is the smallest planet, being about one-third the size of Earth. Neptune, the farthest planet from the sun, is about four times the Earth's diameter.
Earth is small compared to Neptune
Neptune's diameter is slightly less than four times that of the Earth's Neptune has 17 times the mass If you weigh 180 pounds on Earth, you would weigh 202 pounds at Neptune's cloud tops Neptune is 30 times further from the Sun than the Earth
It is one of the four outer giants, Jupiter, Saturn, Uranus and Neptune.
Neptune is bigger than the Earth, nearly 58 times bigger by volume.
