Moon Mass and Life on Earth

Moon Mass and Life on Earth
Our Moon is different from any other moon in our solar system. And as far as we know, it’s different from any other moon orbiting any other planet in our galaxy. The difference has to do with the Moon mass.

No other planet has a moon with a mass that is so large compared to the mass of the planet. While other planets have multiple moons, our single Moon is large enough in relation to our planet that it stabilizes Earth’s rotational tilt at 23.5 degrees in relation to our orbit around the Sun. No other planet in our solar system has such a stable rotation axis tilt. The stable axis allows us to have stable and reliable seasons.

Seasonal changes distribute the Sun’s energy over Earth’s surface allowing plants to grow and food to be produced over a large area. Without the seasons, much of the Earth would be too cold, and some areas would be too hot for advanced life. The Moon has enough mass at the right distance from Earth to make advanced life possible on this planet.

In fact, the Moon has almost too much mass. If the Moon had two percent more mass, it would destabilize the Earth’s tilt. Is there a reason for the Moon to be more massive that it needs to be to stabilize the tilt? Yes, there is. The mass of the Moon creates a pull on the Earth known as tidal friction. That force creates the ocean’s tides which refresh the coastlines.

There is another reason for the large Moon mass. It also slows the Earth’s rotation. In the early Earth, days were shorter. The Moon has put the brakes on our planet’s rotation slowing it to a 24-hour day. Slowing the rotation has affected Earth’s weather, reducing temperature extremes and distributing rainfall more evenly around the Earth.

These are some of the many reasons we need the Moon at its exact size and location. Is it merely another coincidence that the Moon has just the right mass and distance from Earth? No, we believe God planned it that way.
