Would it be bad if the moon went out of orbit?

Yes, I think when people think about the influence of the moon on the earth, the first thing they think of is the tide. This is not the only thing that will affect us. No moon = no moonlight, so every animal or plant that receives the moonlight signal to do something will be affected and the whole food chain will be destroyed. The night will get darker and it will be more difficult for every animal to observe.

Another answer mentioned that if the moon is out of our orbit, it may mean that something very bad happened to make it out of orbit.

Yes, it's happening. Every year, the moon is drifting at a measurable distance: 1.5 inches per year. So 1000 years later, its distance from us is 1500 feet. After billions of years, it will eventually drift away. The moon is vital to maintaining life on earth. There is no moon, and we have almost no tides except those caused by the sun itself. Ocean currents will slowly stop, life in the ocean will eventually die, and all life on earth will eventually die.

But don't worry. About 1 to 200 million years, much less than 1 100 million years, we think that the sun will become very hot and all the water on the earth will evaporate, which will make life on our planet disappear.

This may not be good, but it is also impossible, although it was mentioned in the old TV series "Space" of 1999.

Or, let's assume that any disaster strong enough to pull the moon out of orbit-such as a wandering and passing star-is something we need to worry about more.

The moon is a celestial body orbiting the earth and the only natural satellite of the earth. It is the fifth largest satellite in the solar system, and [13] is the largest planetary satellite relative to the size of the planet it orbits. [f] Among the solar system satellites with known density, this satellite has the second density, second only to Jupiter's satellite Io.

We believe that the moon was formed 4.565438 billion years ago, shortly after the earth. The most widely accepted explanation is that the moon was formed by the debris left by the collision between the earth and the imaginary Mars-sized celestial body Teia. Although Teia's hypothesis has not been denied, the latest research on moon rocks shows that the moon may be older than previously thought.
