What is the gravity of Neptune?
11.15 m/s²Neptune / Gravity
How many Earths could fit inside Neptune?
57 Earths
Neptune is the fourth largest planet in our Solar System and it is the smallest of the giant gas planets. Neptune has a diameter of 34,503 miles (55,528) kilometers. Its volume is 57.7 times the volume of Earth which means that 57 Earths could fit inside of Neptune with a little room left over.
What is Neptune’s mass?
1.024 × 10^26 kg (17.15 M⊕)Neptune / Mass
Which planet has the highest pressure?
Surface Pressure of the Planets and the Sun
| Rank | Name | Surface Pressure (bar) |
|---|---|---|
| 1 | Saturn | >>1000 |
| 2 | Uranus | >>1000 |
| 3 | Neptune | >>1000 |
| 4 | Venus | 92 |
What is Neptune’s composition?
Neptune is very similar to Uranus. It’s made of a thick soup of water, ammonia, and methane over an Earth-sized solid center. Its atmosphere is made of hydrogen, helium, and methane. The methane gives Neptune the same blue color as Uranus.
How much would 100 kg weigh on Neptune?
114 kg
If you weighed 100 kg on Earth, you would weight 114 kg on Neptune. Compare that to the much lower gravity you would feel on the Moon (16.5%) or Mars (37.6%). Neptune has much more mass than Earth. In fact, it has a mass of 17 times the mass of the Earth.
Is Neptune’s gravity stronger or weaker?
The surface gravity on Neptune is about 110% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 110 pounds on Neptune (assuming you could find someplace to, well, stand).
Is Uranus the 3rd largest planet?
Uranus, the third largest planet in our solar system, may be the strangest because it spins on its side. That severe tilt to its rotational axis may result from a great collision long ago. As the seventh planet from the Sun, Uranus takes 84 years to complete an orbit. It is a “gas giant” with no solid surface.
