## How do you calculate the distance to the Moon?

How to Measure the Distance to the Moon Using Trigonometry

1. First, change 0.56 degrees to radians.
2. Input the numbers into the arc-length formula, Enter 0.00977 radians for the radian measure and 2,160 for the arc length: 2,160 = 0.00977 x r.
3. Divide each side by 0.00977. The distance to the moon is.

## What is the average distance to the Moon?

Moon/Distance to Earth

How many kms to the Moon and back?

The average distance between the Earth and the Moon is 384 400 km (238 855 miles). The Moon’s elliptical orbit with the distances at apogee and perigee.

Is the Moon is about 400000 miles from the Earth?

A lunar distance, 384399 km, is the Moon’s average distance to Earth. The lunar distance is approximately 400,000 km, which is a quarter of a million miles or 1.28 light-seconds. This is roughly thirty times Earth’s diameter. The semi-major axis has a value of 384,399 km (238,854 mi).

### Who discovered the distance to the Moon?

Aristarchus around 270 BC derived the Moon’s distance from the duration of a lunar eclipse (Hipparchus later found an independent method). It was commonly accepted in those days that the Earth was a sphere (although its size was only calculated a few years later, by Eratosthenes ).

### How long would it take to walk to the Moon?

So, if a person walked at 3.1 mph (5 km/h) for 4 hours a day, then it would take an estimated 547 days, or nearly 1.5 years to walk the moon’s circumference, assuming your route isn’t too disrupted by craters and you can deal with the temperature changes and radiation.

How far is NASA from the moon?

The average distance to the moon is 382,500 kilometers. The distance varies because the moon travels around Earth in an elliptical orbit. At perigee, the point at which the moon is closest to Earth, the distance is approximately 360,000 kilometers.

How far is the Moon from Earth tonight?

The distance of The Moon from Earth is currently 398,148 kilometers, equivalent to 0.002661 Astronomical Units. Light takes 1.3281 seconds to travel from The Moon and arrive to us.
