End of planet Earth
Encyclopedia : E : EN : END : End of planet Earth
The end of planet Earth refers to when the Earth will either completely cease to exist as a planet or become uninhabitable for life.
According to astronomers, the Earth should last for at least five billion more years before the sun becomes a red giant and possibly will engulf the Earth.
Others say the atmosphere will burn dry out within 1.1 billion years after the sun becomes about 10% hotter, and that the oceans will evaporate within 3.5 billion years when the sun is 40% hotter.
In 3.5 billion years the Andromeda Galaxy may collide with ours and may wipe out some solar systems.
