Can Theia support life?

Theia is the fourth planet from the sun, the second densest, and the seventh largest of all the planets in the Solar system. It is one of only two planets (the other being Earth) that has an environment capable of supporting life.

Why is Earth habitable?

What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

What is Thea a nickname for?

What happened when Theia and earth were near each other?

Astronomers think the collision between Earth and Theia happened at about 4.4 to 4.45 bya; about 0.1 billion years after the Solar System began to form. In astronomical terms, the impact would have been of moderate velocity. Theia is thought to have struck Earth at an oblique angle when Earth was nearly fully formed.

Why didn’t the Earth’s Moon form from a collision with Theia?

Chances are it didn’t. Theia is just one of many hypothesis that could have resulted Earth having it’s moon. The actual collision if it did happen, would not have made much difference to the Earth. The Earth was still cooling (technically it still is), and not settle down enough for any lasting formations.

What would have happened to Earth if it was hit by another planet?

Earth would have gained significant amounts of angular momentum and mass from such a collision. Regardless of the speed and tilt of Earth’s rotation before the impact, it would have experienced a day some five hours long after the impact, and Earth’s equator and the Moon’s orbit would have become coplanar.

What would have happened if there was less water on Earth?

If it was less water then most likely the plate tectonic engine of Earth would never have started up in the first place, so no obduction, subduction or plate-tectonic collision. Any initial land would have been rapidly eroded, leaving only shallow or deep ocean.
