How the Moon and the Earth Affect Each Other


The Moon was once mysterious, but now we know a lot more about it.

For example, we now know that the Moon and the Earth affect each other. The gravitational pulls between the Moon and the Earth keep them in place in outer space. The Moon’s gravity is weaker, because the Moon is smaller than the Earth. Because of this people and objects weigh only one-sixth of what they weigh on Earth when they are on the Moon.

The Moon also affects the tides on Earth. When the Moon is above an ocean, the tides rise. When Earth rotates, the tides shift east to west, making high tides and low tides.

In 1969, Neil Armstrong became the first person to walk on the Moon. As he stepped form the spaceship and onto the Moon, he said “That’s one small step for man, but one giant leap for mankind.”
