How much would a 130 lb person weigh on the sun?

Answer 1

Answer #1:

If you weighed 100 pounds on Earth, you would not weigh anything on the Sun.

This is because the Sun is so hot you would burst into flames before you even

got close enough to it.

===============================

Answer #2:

Naturally, in order to answer the point you're really getting at, we have to

ignore the obvious problems. Such as . . .

-- Neither you, nor anything else, can be "on" the sun without becoming

totally vaporized, and once you're been totally vaporized, it doesn't matter

any more.

-- You can be "on" the Earth. because the Earth has a solid surface that

you can stand on. But you can't be "on" the sun, because the sun is totally

gas, and it has no surface.

Well, there IS a certain 'depth' on the sun ... and on all the other giant gas

balls in the solar system ... that's defined as the "surface" of each body.

We don't need to get into how that depth is defined, but it does give us

a way to compare the surface of Earth to the "surface" of other things that

don't actually have one.

OK. At that distance from the center of the sun, the acceleration of gravity

is 274.87 meters per second2. That number is 28.028 times the same number

on Earth's surface. So any mass at that depth on the sun ... and there's

certainly plenty of it ... weighs 28.028 times as much as it would on Earth.

In particular, a bunch of roiling, churning, incandescant gas that would weigh

100 pounds on Earth weighs 2,803 pounds when it's on the sun at that exact

depth.

Answer 2

Technically the answer is still 120 pounds as this is a measure of mass not weight. Only weight is affected by gravity.

By using the equation of Newton's Second Law:

Force (weight) = mass x acceleration (gravity),

we can determine the weight of an object (ie the force it exerts towards the centre of the gravitational field. But we also need to know the acceleration due to gravity. On Earth this is roughly 9.81 metres per second squared (ms-2) depending on where it is taken and the density of the earth at that point. This however is 275 ms-2 at the surface of the sun.

To find the weight of an object we need the mass in kilograms. So 120 lbs = 54.431 kg.

On Earth:

Weight = 54.431 x 9.81

= 533.96811 Newtons

On the Sun:

Weight = 54.431 x 275

= 14968.525 Newtons

As a comparison a human on earth weighs roughly 800 Newtons.

Hope this helps J

Answer 3

If the person weighed 130lb here, the sun has 28 times more gravitational pull then Earth, so the person would weigh 3,640lb!
