How Far is the Moon from Earth?
The average distance between Earth and the Moon is approximately 384,400 kilometers. This distance is measured from the center of the Earth to the center of the Moon. It may sound like a tremendous distance, but in the cosmic scale of things, it’s relatively close.
Why Does the Distance Vary?
Just like Earth, the Moon doesn’t have a perfectly circular orbit around our planet. Instead, its orbit is slightly elliptical. As a result, the distance between Earth and the Moon can vary throughout the Moon’s orbit.
At its closest point, known as perigee, the Moon is approximately 363,000 kilometers away from Earth. However, at its farthest point, called apogee, the Moon can be as far as 405,000 kilometers away. This difference of approximately 42,000 kilometers makes for a noticeable change in its appearance in the night sky.
How Long Does it Take to Reach the Moon?
The time it takes to travel from Earth to the Moon varies depending on the spacecraft and its trajectory. However, on average, it takes around 3 days for a spacecraft to reach the Moon. This, of course, takes into account the speed of the spacecraft and the course it takes to minimize the travel time.
