Jupiter
You would weigh a little more than double your Earth weight (about 2.36 times) on Jupiter.
If you are on Jupiter, you will weigh more than double. (Weight on Earth taken as reference)
If the object doesn't move to another planet while you double its mass,its weight will also double.
You would weight more than twice your normal weight on Jupiter.
Jupiter is the planet that can double your weight due to its strong gravitational pull. It has a mass much greater than Earth, making your weight heavier if you were to stand on its surface.
Your weight would more than double on Jupiter because its force of attraction is so strong.
There is no maximum weight that a planet can get to. A planet's weight depends on its mass and the gravity it has.
The force of gravity is proportional to the mass, and inversely proportional to the SQUARE of the distance between them. If we double the mass at the same distance, we double the force; if we double the distance, the force is cut to one-FOURTH. So twice the mass and twice the distance; the force will be (800*2)/2^2, or 400.
The mass of the object would remain the same, as it represents the amount of matter within the object. However, the weight of the object would double on the planet with twice the gravity of Earth because weight depends on the gravitational pull experienced by the object.
None. Pluto-Charon was almost considered one in 2006, though that would be a dwarf double planet rather than a true double planet as Pluto is not a planet. In billions of years the Earth and Moon will be a double planet. Also, the question is non-sensical because if it was a double planet then they would both be planets... so there would be no moon. A planet would be considered a double planet with it's opposite planet, not moon.
The weight of an object on a planet depends on the planet's gravity and the mass of the object. The formula to calculate weight is Weight = Mass x Gravity. So, weight on a planet will be different from the weight on Earth depending on the planet's gravity.
First of all, Pluto is not a planet. It was considered a double planet because its largest moon Charon is half its size.
