The Moon Is Moving Away From the Earth

Right now, the moon is gradually moving away from the Earth. Originally, the moon was created when a proto-planet collided with the Earth 4.5 billion years ago. Back then, the Moon was only 14,000 miles away from the Earth. Now, it has moved farther away and is 250,000,000 miles away from our planet.

Each year, the Earth moves 1.48 inches away from the Earth. This is about how fast your fingernails grow. Eventually, this slow change will impact life on Earth. The moon normally influences the Earth’s spin. Without the moon’s presence, the Earth will slow down and become unstable.

When the moon first formed, the early Earth had days that were just five hours long. The moon slowed down the Earth over the course of 4.5 billion years, which is why Earth days are now 24 hours long. According to businessinsider.com, this slowdown will continue to happen over time. By using the daily growth bands on coral, scientists have figured out that Earth days become 19 hours longer every 4.5 billion years.

While it may not seem important, the length of an Earth day has a major impact on our seasons. As the moon moves away from us, the Earth’s rotation will become unstable. This is similar to the way you become unstable when you pedal too slowly on a bicycle. Once this wobble develops, it could lead to extreme temperature variations.

Normally, the Northern Hemisphere is tilted toward the sun during the summer. This gives the Northern Hemisphere warmer weather and longer days. During the winter, the Northern Hemisphere tilts away from the sun and enjoys shorter days. If the planet becomes unstable, then the Earth could develop extreme temperatures during each season. Thankfully, this process will take billions of years to happen, so no one who is currently alive has to worry about it.
