We are making Neptune much bigger than actually it is, but it is just almost thrice the size of Earth. Even though it is the smallest of gas giants, it has a mass more than that of Uranus. So, Neptune is much massive than Earth, at least 17 times, so the volume of Neptune will be at least 50 times the volume of Earth. It will take 3 Earths to make a belt around Neptune. And also, there maybe some objects which are larger than Earth, but smaller than Neptune.
Earth is smaller than Neptune but larger than Venus.
Larger
Neptune is so much larger than Earth you could fit almost 60 Earths inside of it.
Neptune has a greater mass than Earth does.
Earth is about 25% smaller than Neptune.Neptune is about 3.88 times larger than the Earth.
Neptune is bigger than the Earth, nearly 58 times bigger by volume.
Saturn, Uranus and Neptune are smaller than Jupiter but larger than the earth
Saturn, Uranus, and Neptune are all larger than Earth but smaller than Jupiter.
Jupiter, Saturn, Uranus and Neptune are much larger than earth. Venus (slightly), Mars (by half) and Mercury are smaller than earth.
The planet Saturn is considerably larger than the Earth. It is one of the gas giants (along with Jupiter, Uranus, and Neptune) all of which are larger than the Earth.
No planet is smaller than Neptune, but larger than Earth in diameter, but Uranus is there in mass. Uranus, even though larger, is less massive than Neptune. Neptune is a giant planet, but not as large as we believe. It is just 3 or 4 times larger than Earth in diameter, but is 16 times massive. Even Uranus is just 13 times. Jupiter and Saturn are much much bigger than all these planets.
It is larger.
