Question

1. if we could some how bring Europa as close to the sun as Earth is, 1 AU, what do you think would happen?
2.Suppose you have an object that weighs 200 N (45 lbs.) on Earth. How much would that same object weigh on each of the other terrestrial planets?

Answer 1

1. Europa's surface is currently ice, so at 1 AU that would melt, and we would end up with a small water world.
But to orbit at 1 AU, its orbit and Earth's would eventually interfere with each other, and one of us would either be ejected from the solar system or sent into a different orbit (whether closer or farther from the sun would depend on the exact interaction). That would not be a good thing if it was Earth that ended up changing. But even if Earth's orbit wasn't changed too much, it could still end up with a more elliptical orbit. Meaning we would at times be closer to the sun that now and at other times farther, and that would destroy our climate and ecosystems.

2. You can get these answers for yourself by searching the planets on a number of different websites and working out the math.

Answer 2

1. I believe the sun's heat that is given off would start to heat up not only Europe but also the other surround countries, as well as evaporation most/all of the water on Earth. Basically... we would die very soon after that ocurred.
2. Mercury:16.99lbs
Venus:40.95lbs
Mars:14.9999lbs
Jupiter:114.3lbs
Saturn:48.6lbs
Uranus:40.95
Neptune:53.55lbs
Pluto:306lbs
Earth's Moon: 28.125

Answer 3

What do YOU think would happen.

A 20 kg mass would weight about 7 kg on Mercury, 17 kg on Venus, 8 kg on Mars, 53 kg on Jupiter, and about 20 kg on Saturn.
