Another impact hypothesis proposes that both the moon and Earth formed after the collision of two bodies, each 5 times the size of Mars, NASA says.The moon is situated about 239,000 miles (385,000 kilometers) from Earth and has actually an estimated mass of more than 81 million heaps (73.5 million metric tons). The next time you look up at the moon in the night sky, you can take comfort in the idea that its not going anywhere anytime soon.Originally released on Live Science.The moon has actually been Earths close buddy for billions of years, and while our view of its shape and size differs somewhat as it orbits our world, it remains a consistent existence in the sky.

Related: What if the moon vanished tomorrow?Our moon is a solid, rocky body surrounded by an extremely thin layer of gases understood as an exosphere, and the natural satellite formed around the exact same time Earth did, about 4.5 billion years back. Another impact hypothesis proposes that both the moon and Earth formed after the accident of two bodies, each five times the size of Mars, NASA says.The moon is situated about 239,000 miles (385,000 kilometers) from Earth and has an estimated mass of more than 81 million tons (73.5 million metric tons). Its about one-fourth Earths size; if Earth were the size of a nickel, the moon would be about the size of a pea, according to NASA.Images of the moon program that its surface area is pocked with craters of numerous sizes, made by previous effects. Most of the planet-forming rocky particles that once filled the solar system has long considering that dissipated, “so the number of impacts has gone way down now– theres a lot less product to impact the Earth or the moon,” Chodas told Live Science.This artists idea reveals a celestial body about the size of Earths moon slamming at excellent speed into a body the size of Mercury.
