Theia

According to the giant impact hypothesis, Theia was a Mars-sized planet estimated to have existed in our early solar system.

It is believed that about 4.5 billion years ago, Theia collided with Earth in a cataclysmic event.

This collision would have thrown a large amount of debris into space, which would have eventually clumped together and formed our Moon.

The theory suggests that, during the impact, some of the material from Theia merged with the Earth, while the rest accumulated to create our natural satellite.

Evidence for this hypothesis is based on the composition of lunar rocks collected during the Apollo missions, which show similarities to the composition of the Earth's crust.

In addition, computer models and simulations have supported the feasibility of this scenario.

Although Theia is only a theory and there is no direct evidence for its existence, this hypothesis provides a plausible explanation for the formation of the Moon and is widely accepted in the scientific community.
