Why don't moons have moons?
The moon has plenty of gravity. In accordance with its mass and radius, any object weighs about 16.5% as much on the moon's surface as it does on the Earth's surface.
How does Venus compare with the earth radius and mass?
Venus' radius = 0.95 of Earth's Venus' mass = 0.815 of Earth's
Is there a connection between the mass of a planet and how many moons it has?
The mass of a planet has nothing to do with its number of moons. For instance, Mars' mass is much less than that of Earth, yet Mars has two moons (Deimos and Phobos) while the Earth has one. (Luna)
What connections between the mass of a planet and the number of moons it has?
There is no direct connection between the mass of a planet and the number of moons it has. Mars is less massive than Earth but has twice as many moons as does Earth. Jupiter is more massive than either Mars of Earth and has many more moons that either of them.

Why gravitational attraction on moon is one-sixth of the gravitational attraction on earth?
The moons mass is 1/6th the mass of the Earth.
How do mercury radius and mass compare with the earths?
Mercurys mean radius is around 2,439.7 km, which is around 38.39% of earth radius or 0.3829 Earths. Mercurys mass is around 3.3022×10 to the 23 kg, around 5.5% of earths mass or 0.055 Earths.
How is big is Saturn compared to Earth?
Saturn's radius is 9.4 x Earth's radius (equatoral) Saturn's mass is 95.2 x Earth's mass Saturn is 9.5 times further from the Sun than the earth is
Why is there the moons gravity is only16 of the earths?
The earth has a colossal size more mass
How does mercury's size compare to the size of earth?
That depends what you mean by "size". Diameter: 0.38 times the diameter of Earth. Radius: same number, since the radius is half the diameter. Volume: the ratio of the diameters cubed. Mass: 0.055 times Earth's mass.
What is the mass of the planet with the largest radius?
In our solar system, Jupiter is the planet with the largest radius of 71,492 km It has a mass of 1.8986×1027 kg
How big is the earth compeard to the moon?
The Moon's radius is slightly over a quarter that of Earth's, but its mass is only about 1/80 as much as the Earth's mass.
