A Young Moon for Life

Our moon is unique in the solar system. Just the right size and just the right distance, it is positioned to stabilize the tilt of Earth’s axis, providing stable seasonal cycles. Science lacks data so far to know just how unique the Earth-moon relationship in a habitable zone is among other stellar systems. We know from the planets of our own solar system that moons come in all sizes, from tiny Deimos to massive Titan, and orbit in apparently arbitrary radii from their host planets. What astrophysicists can do is predict what would happen on earth if things were different. That’s what one scientist did. Another discovery could change the view of the moon’s surface being unaltered for billions of years.
