Neptune is the eighth and farthest-known planet from the Sun. In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth, slightly more massive than its near-twin Uranus.

No, the planet Neptune is not visible without a telescope from Earth. Due to the distance of Neptune away from Earth, Neptune can only be viewed with high powered telescopes. ... Where Uranus is a little less than 20 AU away from the Sun, Neptune is 30 AU away from the Sun.

Neptune, like the other gas giants in our solar system, doesn't have much of a solid surface to live on. But the planet's largest moon, Triton, could make an interesting place to set up a space colony.

Eris is one of the largest known dwarf planets in our solar system. It's about the same size as Pluto, but is three times farther from the Sun. Eris first appeared to be larger than Pluto. ... The name fits since Eris remains at the center of a scientific debate about the definition of a planet.

Size. Neptune is nearly four times larger than Earth, according to the National Aeronautics and Space Administration (NASA). Neptune's diameter is 30,775 miles across the equator, while Earth's diameter is only 8,000 miles.

(In case you're wondering, though, Mercury is still significantly larger than the dwarf planet Pluto: Pluto's equatorial diameter is just 2,302 km, about half Mercury's width.)

IntroductionDark, 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.

The diameter of Mercury is 4,879.4 km, while the diameter of Jupiter is 142,984 km. In other words, Jupiter is 29.3 times bigger across than Mercury. In terms of volume, you could fit 24,462 Mercurys inside Jupiter. Jupiter even has 5,750 times more mass than Mercury.

Venus: Venus is often referred to as Earth's “sister planet“, and not without good reason. At 12,104 km (7521 mi) in diameter, it is almost the same size as Earth.

Size and Distance With a radius of 36,183.7 miles (58,232 kilometers), Saturn is 9 times wider than Earth. If Earth were the size of a nickel, Saturn would be about as big as a volleyball.

Size and Distance If Earth were the size of a nickel, Neptune would be about as big as a baseball. From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.

Saturn is the second largest planet, big enough to hold more than 780 Earths, and is more massive than any other planet except Jupiter; it's 95 times Earths mass. However Saturn is the lowest density of all planets, and is the only one that weighs less than water. If Saturn were in a huge bath tub it would float.

Pluto is only 1,430 miles (2,302 kilometers) in diameter and is about 1/6th the size of Earth. Pluto is actually smaller than our own Moon!

Uranus is slightly larger in diameter than its neighbor Neptune, yet smaller in mass. It is the second least dense planet; Saturn is the least dense of all. Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus' cloud tops.

Giant. Neptune is about four times wider than Earth. If Earth were a large apple, Neptune would be the size of a basketball.
