Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. The average distance from the center of the planet to its surface is 15,299 miles (24,622 kilometers).
What is the sixth biggest planet?
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine times that of Earth.
|Polar radius||54,364 km (33,780 mi) 8.552 Earths|
|Circumference||365882.4 km equatorial (227348.8 mi)|

What’s Neptune made of?
Structure. Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80 percent or more) of the planet’s mass is made up of a hot dense fluid of “icy” materials—water, methane and ammonia—above a small, rocky core. Of the giant planets, Neptune is the densest.
Who is bigger Neptune or Uranus?
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.
Which is biggest planet on Earth?
Jupiter, being the biggest planet, gets its name from the king of the ancient Roman gods. Despite its size, Jupiter has the shortest day of any other planet; it only takes about 10 hours for a complete rotation.
Which is the 5 largest planet?
Biggest Planets In Our Solar System
Can u live on Neptune?
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. … Though there are slight winds in Triton’s thin atmosphere, you wouldn’t feel any breeze while standing on the surface.
Is Neptune big or small?
Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. The average distance from the center of the planet to its surface is 15,299 miles (24,622 kilometers). But like most spinning bodies, Neptune’s rotation causes it to bulge slightly around the equator.
Does it rain diamonds on Neptune?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. … Beyond the lingering mystery of the diamond rain, there’s a big loss in our failure to study Uranus and Neptune inside and out.
How cold is Neptune?
The average temperature on Neptune is about minus 200 degrees Celsius (minus 392 degrees Fahrenheit). Neptune, the farthest known planet of our solar system, is located about 30 times farther away from the sun than Earth is.
How long is 1 day on Neptune?

Does Neptune have oxygen?
“At high altitudes, Neptune’s atmosphere is 80% hydrogen and 19% helium” (Wikipedia). No significant abundancy of free oxygen to react with. A source of oxygen could easily made burn on Neptune, like a source of hydrogen on Earth. … Hence some oxygen would remain in the atmosphere.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Why does Uranus spin backwards?
In 2011, simulations suggested that a number of smaller collisions, rather than one big impact, knocked Uranus’ spin to an angle of 98 degrees. … An alternative explanation put forward by astronomers in 2009 is that Uranus once had a large moon, the gravitational pull of which caused the planet to fall on its side.
What planet would float in water?
Saturn could float in water because it is mostly made of gas.
