How Far is the Moon from California?
A Cosmic Distance
Have you ever looked up at the moon and wondered how far away it really is? It's a question that has puzzled humans for centuries, and even today, it can be a bit tricky to wrap your head around the vast distance involved.
So, just how far is the moon from California? Well, to give you a rough idea, it's about 238,855 miles (384,400 kilometers) away. That's a long way! To put it into perspective, it would take you about a month to drive to the moon in a car, assuming you could drive on the moon's surface and didn't need to stop for gas or snacks.
The Moon's Orbit
The moon doesn't stay in one place; it orbits the Earth. This means that the distance between the moon and California is constantly changing. At its closest point, the moon is about 225,623 miles (362,773 kilometers) away, and at its farthest point, it's about 252,088 miles (405,696 kilometers) away.
Measuring the Distance
How do we know how far the moon is from Earth? Scientists have been measuring the distance to the moon for centuries using a variety of methods. One of the earliest methods involved measuring the angle between the Earth, the moon, and a star. More modern methods use lasers and radar to bounce signals off the moon and measure the time it takes for the signals to return.
