What is the Distance Between Earth and Moon?

The average distance between Earth and the Moon measures 384,400 kilometers (238,855 miles), which is roughly 30 times the diameter of Earth. Due to the Moon’s elliptical orbit around Earth, the actual distance between the two bodies varies slightly.

When the Moon is closest to Earth, known as perigee, it is approximately 363,104 kilometers (225,623 miles) away. Conversely, at its farthest point from Earth, called apogee, the Moon is about 405,696 kilometers (252,088 miles) distant.

An important aspect to note about the Moon is its impact on tides and eclipses. The Moon’s distance from Earth directly influences the strength of ocean tides. When the Moon is nearer, its gravitational pull is stronger, resulting in higher tides. Conversely, when the Moon is farther away, its gravitational pull weakens, causing lower tides.

Additionally, the Moon’s distance from Earth affects the appearance of solar eclipses. During perigee, the Moon appears larger in the sky, enabling it to completely block out the Sun during a solar eclipse. Conversely, during apogee, the Moon appears smaller and may only partially obscure the Sun during a solar eclipse.

The Moon’s distance from Earth is continually changing due to the gravitational forces exerted by the Sun and other planets. Nonetheless, the average distance between the two bodies has remained relatively constant for billions of years.

The Moon, Earth’s sole natural satellite, is believed to have formed approximately 4.5 billion years ago from a colossal collision with Earth. This impact ejected a substantial amount of debris into space, which eventually coalesced to form the Moon. Today, the Moon showcases a captivating and enigmatic landscape, featuring mountains, valleys, craters, and lava flows. There are even indications that liquid water may have existed on its surface in the past.
