Neptune and Uranus are gaseous planets and Earth has a rocky core and surface. The atoms are closer together than those of Uranus and Saturn. Common Sense gave me that answer. Maybe you should visit it some time.
The Radius from the Center of Neptune is 24,622 km, (15,299 mi) while it is 25,362 km, (15,759 mi) for Uranus. So Uranus is bigger than Neptune, but Neptune has a greater mass. In other words Neptune is smaller but denser. Neptune has a radius of 3.88 Earth radii while Neptune has a radius of 4.01 Earth radii. In terms of mass, Neptune is 17.15 Earth masses while Uranus has 14.536 Earth masses.
Scientists know the masses of both Uranus and Neptune because of the effects of their gravity on other objects, and the fact that their sizes are easy enough to measure. Neptune has more mass than Uranus and is slightly smaller, which makes it denser.
Neptune is farther away from the Earth than Uranus Order of Planets: Mercury, Venus, earth, mars, jupiter, saturn, uranus, neptune
Uranus, Neptune, Saturn, and all have more mass than Earth.
Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars and Mercury Distances from the Sun are Mercury = 0.387 Astronomical Units from the Sun, Venus = 0.723, Earth=1, Mars=1.52, Jupiter = 5.20, Saturn =9.54, Uranus :] = 19.2, Neptune=30.1,
Uranus is a little bit bigger if you measure it with Neptune, but even though Uranus is bigger- Neptune is actually heavier if you measure their weight. Which means even if Uranus is bigger, Neptune is heavier.
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.
Uranus. Neptune is almost as big and actually has more mass, because it's denser than Uranus.
Pluto is not a planet so that would be Mercury is 13.72% smaller. Venus is 0.23% smaller. Mars is 9.42% smaller. So that means 3 planets are smaller than Earth.
Yes, Uranus is the closest planet to Neptune.
In our solar system there are 4 planets larger than Earth, which are collectively known as the gas giants; these are Jupiter, Saturn, Uranus, and Neptune. There are many other planets larger than Earth in other solar systems as well.
Jupiter, Saturn, Uranus and Neptune.
