Question

Would a coke can be lighter or heavier due to the effects of gravity from each of the nine planets?

Answer 1

I think it would depend on the gravites of each planet as they are all different.

Answer 2

It depends on the orientation of the planets to the coke can.

It will never be detectable, however, because the gravities of the people in the room and the trucks passing by outside, etc., will dominate the effects of the planets.

Answer 3

Weight is mass * acceleration of gravity.  The mass of the coke can stays the same, so all you need to look at is how much gravity the planets have.  If they have less, then it's lighter.

Mercury and Mars should be lighter, Venus about the same, and heavier on the rest.

Answer 4

Yes.

Answer 5

Yes, except that there are only eight planets in the Solar System.

More specifically, as compared to how much it weighs on the Earth, it would weigh less on Mercury, Venus and Mars, and more on Jupiter, Saturn, Uranus and Neptune. It would also weigh less on all known moons and KBOs (Kuiper Belt objects) in the Solar System, but more on the Sun.
