Earth would be destroy due to the gravity force of that planet.
nothing would happen
Weight.
If the star Betelgeuse replaced the Sun, most planets will be inside the star, even Jupiter. It would outshine the Sun like the Sun outshines the Moon.
Well, first you would have to find the object's mass and weight. Since the gravitational force on Jupiter is approximately 2.3 times the gravitational force, you would have to multiply the mass times 2.3 and the weight times 2.3.
scientifically speaking,I calculate that it would become heavier.
Jupiter is so big that the Earth would orbit Jupiter.
nothing would happen
Even on Jupiter, or in the vicinity of Jupiter, the sun is still the brightest object in the sky. The brightest planet would be Saturn.
nothing would happen because comets hit Jupiter when it is hot and it does not burn up it. if Jupiter was a a bit bigger it would start to glow.
Weight.
Because the new moon would have a higher gravitational pull, the earth would start to orbit around it as if it was the new moon's moon. This would cause the new moon to become a sun causing the Sun to crash into the new sun causing a supernova erasing the entire galaxy.
It would be heavier.
If the star Betelgeuse replaced the Sun, most planets will be inside the star, even Jupiter. It would outshine the Sun like the Sun outshines the Moon.
An object that weighed 100 pounds, would weigh 236 pounds on Jupiter.
they would die because of the gas
There are lots of ifs in this question and answer. If the 100 pound Earth object could rest on the outer surface of Jupiter the answer would be 250 pounds. But, Jupiter is a gas planet. That is, Jupiter is primarily made of gas and liquid. So, the object could not rest on the outer surface. There may be a solid surface near it's center but no one knows. Jupiter is 318 times as heavy as Earth so if Jupiter were solid and the size of Earth the object would weigh 318 times a much or 31,800 pounds. But, it is much larger than Earth so the outer surface is much farther from the center. The farther away the object is from the center the less the object will weigh.
Jupiter has no definite surface. If you did not have a suitable aircraft you would simply fall into the planet's interior to be crushed by the immense pressure.
