The earth is six times more massive than the moon. That keeps the moon in orbit around it, just as the mass of the sun keeps the earth in orbit around it.

Is the escape velocity higher for the earth or the moon?

The mass of an object is the same wherever it may be. The weight of an object changes however. The weight of an object is the product of its mass times gravity. Gravity is greater on earth than it is on the moon, so an object will weigh more on earth.


Will the moon escape from the earth?

yes, it creeps away from earth at about an inch a year.


Which requires more fuel -- a rocket going from the Earth to the Moon or a rocket coming from the Moon to Earth?

A rocket traveling from the Earth to the Moon requires more fuel due to Earth's stronger gravitational pull. The rocket needs to overcome Earth's gravity to escape its orbit, which requires a significant amount of energy compared to landing and taking off from the Moon, where the gravitational pull is weaker.


Can you escape the earth gravity by going to the moon?

No. If you are on the moon, then the moon is the dominant gravitational body in your area, but the moon still orbits Earth and so is still very much under the influence of Earth's gravity.


Will the earth and the moon join?

Not hardly. The moon is moving away from the Earth at a rate of a few inches per year. In about 25000 years, the moon may have the potential to escape the gravity of the Earth.


There is no atmosphere on the moon. Explain on the basis of escape velocity?

The moon's escape velocity is lower than the average velocity of gas particles in its atmosphere, so the moon cannot retain an atmosphere as the gas particles would escape into space. This is why the moon has no significant atmosphere.


Would a spacecraft need as much fuel to escape from the moons gravity as it would to escape from the earths?

Escape velocity for the moon is a little over 5000 miles per hour. For the earth it is about 25,000 miles per hour. So the moon requires a fifth of the energy required to escape the earth.


What forces need to be overcome to get to the moon?

If you want to get out of the earth, say for example you want to get to the moon, then you will need to escape gravity.


Why is thermal escape of atmospheric gas much easier from the Moon than from Earth?

Thermal escape of atmospheric gas is much easier from the Moon than from Earth because the Moon has a much weaker gravitational force, which means that gas particles can escape more easily. Additionally, the Moon lacks a magnetic field to protect its atmosphere from being stripped away by solar wind and radiation.


How long will it take for the moon to drift out of our orbit?

The Moon will drift farther and farther from Earth, while Earth slows down, until Earth always shows the Moon the same face (just as the Moon already shows Earth the same face all the time). It doesn't seem that the Moon will completely escape from Earth's gravity.


The ratio of the radius of that of the moon is 10 .The ratio of g on the earth and on the moon is 6 then what is the ratio of the escape velocity from earth's surface to that from the moon's surface?

The escape velocity is given by √2gR Hence it's value Ve on the earth and Vm on the moon is Ve = √2ge.Re Vm = √2gm.Rm Therefore , their ratio = Ve/Vm = √ge.Re/√gm.Rm = √6 x 10 = √60 = 8 nearly


What is the escape velocity from the moon for a lunar landing module sitting on the Moon's surface?

The lunar escape velocity, regardless of what object is trying to escape, is about 2.38 km/s, or about 1.5 mi/s. (This is about 5324 mph, compared to about 25,000 mph on Earth.)
