How Many Moons Are Enough?

How Many Moons Are Enough?
When it comes to moons, it seems that Earth got cheated. We have only one moon while Mars has two. Neptune has fourteen moons. Uranus has twenty-seven. Saturn not only has rings, but it also has sixty-two moons. (Update- We now know that Saturn has 82 moons! Lucky Jupiter has sixty-seven! (Update- It’s now 79!) To add to the embarrassment, puny little Pluto, which is no longer considered a planet, has five times as many moons as Earth has! The only bragging point we have is that we can say we have more moons than Mercury and Venus. (They have none.) So how many moons are enough?

Actually, one works very nicely. Our single moon is critical to the existence of life on Earth. It’s because of the moon that Earth has a stable tilt on its axis of 23.5 degrees. That tilt prevents temperature extremes on this planet. With no inclination, the area of the Equator would be extremely hot and the poles extremely cold and dark all year. With a greater tilt, seasonal weather changes would be extreme all over the planet. Because of the angle of the inclination, we have proper seasons, and the air gets mixed to temper the weather extremes.

Our moon has the right mass at the right distance to keep Earth’s tilt stable. The moon plays several crucial roles in making our planet a great place to live, but stabilizing the tilt is one that’s extremely important. So how many moons are enough? I would say that one moon of the right size and at the right distance is just right.

Oh, and those other planets with more moons — none of them are habitable. Guess who has bragging rights now? Thank God that he gave us a just-right moon, and we don’t need any more. We see evidence of God’s design in every detail of our planet.
