If astronomers discovered a planet that had 8 times the radius of earth but was the same mass how would your weight on this planet compare to your weight on earth?

Weight is the amount of gravity affecting your mass... There are different levels of gravity at different places on Earth, so in this case if gravity is higher your weight will raise, if it is lower your weight will decrease

∙ 8y agoYou would weigh 1/64 your weight on Earth. Gravitational acceleration is directly proportional to the mass of the object and inversely proportional to the square of the distance from the center. On a planet 8 times Earth's radius you would be 8 times farther away from the center and 8^2=64.

∙ 10y agoYour weight would be greater, or less, depending on the planet's gravitational field. Here is one example: for Jupiter, the Wikipedia lists an "equatorial surface gravity" of 24.79 m/s2; this means that you would weigh 24.79 newton/kilogram. For comparison, on Earth you weigh about 9.8 newton for every kilogram. The Wikipedia also lists the "equational surface gravity" as 2.528 g; this simply means that Jupiter's gravitational field is 2.528 times stronger than that of Earth (and that you would weigh that much more).
Note 1: Jupiter doesn't really have a surface on which you might stand.
Note 2: m/s2 is equivalent to newton/kilogram.

∙ 13y agoYou'r weight would be greater because the more mass the greater the gravitational pull which is what causes weight in the first place
Wiki User
∙ 10y agoYour 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.
Wiki User
∙ 11y agoNo you would not because other planets have different gravitational pulls.
Wiki User
∙ 7y agoYour weight would increase in direct proportion to that planet's mass.
Wiki User
∙ 12y agoIt would be greater.

What is the origin of the word radium?
It is from the Latin radius and means ray in English. It was coined by the Marie and Pierre Curie, who discovered this radioactive element.
An object of mass 0.50 kg is transported to the surface of Planet X where the object's weight is measured to be 20 N The radius of the planet is 4000000 m What free fall acceleration will the 0.5kg OJ?
18 m/s
What does gravity determine?
A lot of scientist's believe that gravity is determined by the size of the planet. I however, believe that gravity is determined by the speed the planet is moving around the star and the speed of the planets rotation.
What is acceleration due to gravity on surface of planet that has radius half that of earth and same average density as earth?
g=Gx4(pi)/3xr3x(rho)/r2=Gx4x(pi)x(rho)xr/3Now if the radius is halved then acceleration will also halve.
Why do scientist developed the solar Mass and solar radius?
In order to conveniently compare the distances from the various planets, astronomers devised a measure called the "astronomical unit". The Earth is one AU from the Sun. In order to conveniently compare the sizes of other stars to our Sun, astronomers use a "solar mass" as the mass of the Sun. and a "solar radius" as the radius of our Sun. This helps to make the comparisons more obvious to non-astronomers.
Which is the biggest planet discovered?
The largest yet discovered, designated HAT-P-32b, that is 0.941 times Jupiter's mass, and 2.037 times Jupiter's radius.
Who discovered the Radius of a circle?
tejeswar sivaji vechemgi discovered radius in circle
Which planet has the largest radius?
Jupiter is the largest planet and therefore has the largest radius. The radius of Jupiter is 43,441 miles (69,911 kilometers).
Is Jupiter the largest planet?
The largest planet within our solar system is Jupiter. However, Astronomers say they have discovered what appears to be an entirely new kind of planet, an extra-large gas giant unlike any known world in our solar system or beyond. It is the largest planet ever discovered and boasts a radius nearly 1.4 times larger than Jupiter's. Click on the related links section indicated below to read about this new and exciting discovery.

What is the nearest planet to WASP-17?
It is known as Wasp-17b, discovered in 2009. The planet is believed to have a radius 1.991 times (nearly double) that of Jupiter but a mass of only 0.486 times (less than half).
What is the distance from earth to the furthest planet in our galaxy?
Astronomers once believed that planets were probably rare and unusual, and that tere might not be very many planets. However, recent discoveries indicate that planets are far more common; in fact, almost every star that astronomers have closely observed is discovered to have some planets! So it is likely that the "furthest planet in our galaxy" is on the other side of the galaxy from the Earth. The Milky Way galaxy has a radius of about 40,000 light years, and our solar system is about 3/4 of the way out from the center. So the "furthest planet in our galaxy" is probably somewhere near 70,000 light years away.
