What would happen if planets replaced the moon?

An incredible video shows what we would see if the planets replaced the moon. But that would turn Earth into a volcanic hellscape. If Jupiter were as close to Earth as the moon, our planet would become one of the gas giant’s moons. Its gravity would also bring volcanic destruction to Earth.

What would happen to Earth if Mars exploded?

Debris could (maybe) hit Earth After all, there would just be more asteroids floating around from the explosion. For one, Mars is about twice as far from Earth as Venus is (via The Planets), and is considerably smaller than Venus (via NASA).

What would happen if Jupiter was as close to Earth as the moon?

The gravitational pull from Jupiter’s other nearby moons, and the planet itself, would generate extreme tidal forces. These would actually generate a lot of heat on our planet-moon, but internally. One year on Earth, is one month on Jupiter, since it takes Jupiter 12 years to go around the Sun.

Why isn’t Mercury pulled into the Sun?

Mercury, like the other planets, is in a stable orbit around the Sun. A planet’s orbit is a geodesic through curved spacetime. A geodesic being the 4 dimensional equivalent of a straight line. So, Mercury is unlikely to fall into the Sun.

What would happen if Earth and Mars collide?

Based on this same information, if Earth and its new moon Mars were to collide, history would start repeating itself all over again…at least until the Sun becomes a red giant and consumes the inner solar system. The plus side to having Mars as our companion would be its new-found accessibility.

What would happen if we replaced Luna with Mars?

Therefore, if Luna was replaced with Mars, then it’s likely that there would be more light visible at night. It would make it all the more eerie if it put a red tint on the night time landscape. Now, Mars isn’t so massive, it would be in danger of plunging into Earth fairly quickly, unlike Jupiter…that would be a different story.

What would happen if there was no atmosphere on Mars?

Colose noted that without a thicker atmosphere or ocean, heat would not be transported efficiently around Mars. This would lead to extreme seasons and temperature gradients between the day and night. Mars’s thin atmosphere produces a surface pressure of just 6 millibars, compared to 1 bar on Earth.

What would happen if Venus orbited Mars?

Venus has a very high albedo, meaning that the planet reflects roughly 75\% of the radiation it receives. The stifling temperatures at the planet surface are due not to a high level of sunlight but to the thickness of the atmosphere. Conditions on the planet may therefore not be immediately affected if Venus orbited in Mars’s cooler location.
