'New' Planet Found Is Actually Earth 4 Billion Years Ago

After Earth's resources have been completely depleted, a group of astronauts travels across space to find the perfect planet to terraform only to get stranded on a dangerous new land.
In 2012, a new planet was discovered by scientists.
The new planet was called "Kepler-22b" and was said to be twice the size of Earth.
However, new research has shown that the planet is actually Earth from 4 billion years ago.
The planet is now known as "Theia" and is about the size of Earth's moon.
Theia is thought to have collided with Earth to form the moon.
Theia is now a dwarf planet orbiting the sun.
The discovery of Theia could help scientists better understand the formation of the solar system.
