Mass of Planet X divided by volume of Planet X

The mass of the planet Mercury is estimated as 3.3 x 1023 kilograms (3.3 x 1020 tonnes or 3.6 x 1020 US tons). This is only 5.5 % of the mass of the Earth.

That question is easily answered when the mass and radius of "Planet X" are known ...a tough assignment, since there is no such planet.

It is about 4.87 x 1024 kilograms. That's about 81.5% of the Earth's mass.

In order to calculate that figure, we need to know the mass of planet x and the radius of its surface. These are particularly difficult to measure in the case of planet x, primarily because it doesn't exist.

The mass of dwarf planet Pluto is about 1.3 x 1022 kg, or about 2.87 x 1022 pounds. However, we don't normally talk about how much a planet weighs - we talk about how much mass the planet has. Mass and weight are two different things.

The mass of the dwarf planet Pluto is about 1.3 x 10^22 kg, or about 0.002 the mass of the Earth.

Errors in the calculations of Neptune's mass led scientists to believe that there was another planet affecting Uranus' orbit. Scientist proceeded to dub this planet Planet X.

Planet Mars has a mass of 639 x 1021 kilograms (639,000,000,000,000,000,000,000kg)

The number depends on what planet and what person.In order to give you a number, we'll take the example of the earth and me.Mass of earth: 5.97 x 1024 kgMass of me: 85.3 kgMass of earth = (5.97 x 1024 / 85.3) = 7.0008 x 1022 (rounded)The mass of the earth is 70,008,000,000,000,000,000,000 as much as my mass. (rounded)(Actually 1 less, because my mass is included in the earth's mass.)

Saturn with a mass of 5.6846 &times; 1026 kgNeptune has a mass of 1.0243 x 1026 kg

The total mass of all eight planets is around 2.67 x 1027 kg

No. Planet X was a provisional name for a planet believed to exist beyond the orbit of Neptune based on a slight anomaly in its orbit. It was later realized that the anomaly was due to a miscalculation of the mass of Uranus.

With Earth's mass at about 5.98 x 10^24 kg, it would be Saturn at about 570 x 10^24 kg, with a mass ratio 1:95.18

Planet X does not exist. The idea of planet X was introduced because of discrepancies in the orbit of Uranus that led some scientists to think the gravity of another, undiscovered planet was pulling on it. The discrepancy was later found to be due to a small error in the estimated mass of Neptune.

No, the mass of a planet does not equal the size of that particular planet.

To weigh a planet, you have to find its mass.

The mass of planet Earth is 5.9736 &Atilde;&mdash; 1024 kg

Jupiter is the moss massive planet that revolves around the sun, with a mass of 1.8988 x 1027 kg. This is 234% more mass than the next massive planet, Saturn, which has a mass of 5.685 x 1026 kg.

In a way, size does not effect a planet's "gravity", its mass does. The more mass a planet has, the stronger its gravitational force.But the "surface gravity" is affected by the radius of the planet. That's because it depends on the distance of the surface from the center of the planet.The important equation here is based on Newton's Law of Gravitation:Gravitational Force = G x M x m / d x d (where G is the Gravitational constant,M is the planet's mass, m is the mass of an object being attracted, and d is thedistance between the centers of the masses).

planet x is real you just have to believe and planet x does not have a x on it.dumb

Planet X does not exist - it was a hypothetical planet.

Electron. An electron has a mass of 9.11 x 10-28 grams.
