Earth and the Moon Will Collide in 65 Billion Years

1Earth and Moon Collision

The moon is currently spinning away from Earth at a rate of around 3.8 centimetres a year.

But experts believe that in the future this could change, and the two bodies could one day be on a collision course.

If the moon and Earth collide, the energy released in the merging would melt the Earth into a magma ocean.

Thankfully, the catastrophic event is not forecast to occur for some 65 billion years.

HOW IT WILL HAPPEN

In around six billion years, the sun will enter what is known as the ‘red giant phase’ of its evolution.

This will begin once all hydrogen is exhausted in the core and the inert helium ash that has built up there becomes unstable and collapses under its own weight.

The sun’s core will become a burned-out remnant white dwarf, while the outer layers of the sun will expand outwards beyond Earth’s orbit.

This will sap energy from the Earth-moon system.

This would cause the moon to start creeping towards the Earth.

In 65 billion years, the moon could collide with Earth transforming it into a massive ball of magma.
