Earth's Moon is a Rarity

Smivs writes "Scientists have concluded that moons like the Earth's are actually quite rare. Only 5-10% of planetary systems are likely to contain moons formed by planetary collisions. 'By the time the Earth's moon formed, when the Sun was 30 million years old, the planet formation process in our Solar System should have been approaching its end. In the latest study, Dr Gorlova's team looked at the heat signature of stars using the infrared. This allows astronomers to predict how much of that heat comes from the star itself and how much is re-emitted by dusty material encircling it.'"

Wrong, sir.

Wrong, my good fellow. The Earth doesn't revolve around the moon, and the moon doesn't revolve around Earth. They actually both revolve around a point that astronomers call the apotex, which lies about 187 million miles from Earth.
