What would the mass of an astronaut with the weight of 80 kg be on a planet?

That depends on the planet. Gravitation on different planets varies. On planet Earth, you multiply by 9.8; the result is in Newtons.

What plant would a person weight the most?
On whichever planet had the greatest mass.
Why is an an astronaut's weight different on different planets?
Weight, a commonly misunderstood term, is the force of gravity on a mass. Mass is constant, but weight can vary depending on the gravitational field. Gravity is a force that is exerted on an object by another object. The formula for weight is: G x m1 x m2 / r2 where G is the "gravitational constant", m1 is the mass of one object and m2 is the mass of the other object. The distance between the objects is r. The gravity of a planet acts as if all the mass is at the center of the planet. So, for an astronaut on the planet surface, r in the equation is the radius of the planet. The weight of an astronaut is different on different planets because the masses of the planets and their diameters are different from the Earth, making the force of gravity stronger or weaker, thus altering the weight. In fact the "surface gravity" on Mars and Mercury is almost exactly equal. That's because Mars has a bigger mass, but also a bigger diameter. In this case, these two factors cancel out almost exactly. Incidentally, an astronaut couldn't actually stand on the surface of one of the "gas giant" planets because the "surfaces" are gas. More details: the rotation speed of the planet affects the effective gravitational force you feel, because of centrifugal effects. This is particularly important in the case of large fast spinning planets like Jupiter and Saturn.
How much would a 100g weight weigh on mercury?
Considering that grams are a unit of mass, their mass would still be 100g. If you used a unit of weight, such as pounds, the relative weight of an object would change from planet to planet. On Mercury, a person who weighed 100 lbs normally would instead weigh 38 lbs.
What happens to your mass as you move from planet to planet?
Your mass does not change. Your weight, however, changes in proportion to the gravity of each planet.
Is the mass of the astronaut on Mars bigger smaller or the same compared with on Earth?
You would have the same mass on the Earth as you would on the moon. You would just weigh less on the moon because there is less gravity there than on the moon.
Would you have less mass or less weight on the smaller moon?
The mass of the astronaut remains the same. However, the weight of the astronaut is less on the moon.
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.
Why does and astronaut weight is different even though the mass is the same?
weight of any person would differ on other planet as weight is the amount of gravitation pulling an object. whereas, mass is the amount of matter in an object. amount of matter remains same but the gravitation changes.
What is the difference between the astronaut's mass on the earth and on the moon?
There is no difference in an astronaut's mass no matter where he or she might be. Mass is a constant, as opposed to weight which is dependent upon acceleration.None.Put simply. Mass is a measurement of how much matter is in an object, whereas weight is a measurement of how hard gravity is pulling on that object. As their is less gravity on the moon, your weight would be different, your mass would not.
Do astronauts have weight in space?
Any object that has mass has weight even in space. If an astronaut weighs 195 pounds while standing on the planet then he/she will also weigh 195 pounds while in space. Earths gravity, which determined the weight, will exert the same force on this astronaut because the mass is the same. While in space, it may appear the astronaut is "floating", he/she is actually in free fall. What this means is, as they travel around the planet they are in reality "falling" to Earth but, for every inch they fall, the planet move an inch out of their way.
How would your weight change on the surface of an earth sized planet whose mass was greater the earths Why.?
Your weight is directly proportional to the mass and gravity of the planet, if the planet has a greater gravity and mass, you will weigh more.
On which planet would your mass be greatest?
Your mass is the same regardless of where you are. Your weight would be greatest on Jupiter.
What planet would your mass be the greatest?
You mass is the same no matter where you are. You weight would be greatest on Jupiter.
On which planet would mass be greatest?
Your mass is the same regardless of where you are. Your weight would be greatest on Jupiter.
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.
Which weighs more an orbiting spacecraft or its astronaut?
Weight in orbit would be equal--Zero. The difference would be mass...
Would your weight increase on the moon?
No. As long as you continued to eat your astronaut food and do your astronaut exercises, your weight would remain constant on the moon. But it would only be about 16% of your weight on Earth. Your mass would be the same on the moon as it is on Earth, and would also not change while you're there.
