Nothing at all. His or her mass remains unchanged (unless of course a diet or overeating results in a loss or gain of mass). What will change is weight. Weight is the word we commonly use to describe the potential falling energy of a body whose acceleration in a gravitational system is interrupted (for instance, by the surface of the Earth).
When you are standing on the Earth, the planet's gravitational pull is constantly trying to accelerate the mass of your body towards the center of mass of the Earth. That pull results in weight. If you are falling through the air (or space) around the Earth (or any other body), you still have the same mass, but you have no "weight." Objects (or astronauts) in orbit around the Earth are actually doing a specialized kind of "falling," and as such have no weight. There is one special case in which your hypothetical astronaut's mass would change: Albert Einstein's special theory of relativity states that if your astronaut began to travel at a substantial percentage of the speed of light (186,000 miles per second), his or her mass would actually increase until, at the speed of light, he or she would have infinite mass. In the practical world, though, no system we've been able to devise could begin to push an astronaut fast enough for this special case to become measurable.

∙ 13y agoAs astronauts travel away from Earth orbit, the effect of gravity decreases, until it is practically zero at a distance of several thousand miles.
(The force exerted by gravity is inversely proportional as the square of the change in distance. At twice the distance from the center of mass, gravity is only 1/4 as strong, and at three times the distance, 1/9 as strong.)

and doesn't change.

When an astronaut lands on the moon its mass is?
The mass is the quantity of matter in the body and therefore it is the same on the Moon as on Earth or anywhere else, the weight however, being the force executed by gravity on the mass, changes and therefore on the Moon it would be close to 6 times less than on Earth.
How will you capitalize this sentence neil Armstrong a famous astronaut landed on the moon?
Neil Armstrong is a famous astronaut who landed on the moon.
Did Malaysian astronaut land on moon?
No, only Americans have landed on the moon.
Is an astronaut lighter on the moon?
Anyone on the moon has the same mass as he has anywhere else, but because the moon's gravity is only a small fraction of what earth gravity is, he will weigh less, and will feel like he is lighter. Remember that mass is "fixed" for a person or object, but "weight" can vary depending on the gravity in which the mass is placed. Your mass on earth and on the moon are the same. Your weight on the moon will be only a bit more than .16 times what it is on earth. A "rough" figure is that you weigh about 1/7th as much on the moon as on earth.
How was the first astronaut on the moon?
Neil Armstrong.
What happens to the mass of an astronaut when he is on the moon?
Nothing, but his weight is 1/6 of his weight on Earth.
Why does an astronaut weigh less on the moon?
The astronaut's mass is the same on the moon but the gravitational force applied on the astronaut is weaker thus the astronaut appears to weigh less.
What is the mass in kilograms of an astronaut on the moon who weighs 165 lbs on the earth?
The mass in kilograms of an astronaut on the Moon who weighs 165 lbs on Earth is 12.4kg
When an astronaut lands on the moon what is his mass?
His mass does not change, only his relative weight.
What is a astronauts mass on the moon?
Irrespective of where the astronaut is, their mass is going to be remain the same
An astronaut on the moon has the same mass as she did on earth but has less?
mass doesnt change but weight does
Why would an astronaut weigh less on the moon than earth?
The moon is considerably smaller than the Earth, both in diameter and in mass, and it therefore has a much weaker gravitational field. The weight of an astronaut on the moon is the result of the mass of the astronaut, which is not changed by going to the moon, and the gravitation field of the moon. A weaker gravitational field produces a lower weight.
Is the mass of an astronaut more or less on the moon or on earth?
The mass of an astronaut remains the same whether they are on the moon or on Earth. Mass is a measure of the amount of matter an object has and is independent of the gravitational force acting on it. However, the weight of an astronaut would be less on the moon compared to Earth due to the moon's weaker gravitational pull.
An astronaut on the moon would have the same as on Earth?
-- name -- age -- mass
When an astronaut walks on the moon is either her mass or her weight the same as on earths?
The mass is the same; the weight is not.
What happens when an astronaut kills another astronaut on the moon?
They have gone to the moon not to kill each other, but for a more purposeful mission. They could have done it on earth.
Why does an astronaut weigh less on the moon that on earth?
Your weight is a function (G=mg) of the gravitational pull (g) and the mass of the object in question (m). The mass of the Moon is only 1/6 that of Earth, so the astronaut on the Moon weighs only 1/6th as much as he does on Earth. His mass does not change.
