# How many fly to the moon?

It is no secret that people have long dreamed of flights into space - unexplored, vast expanses fascinate and beckon, but space tourism has not yet become a mass industry. Why so? Yes, because getting to another planet is not so easy. Even to the moon, to which, it seems to be within reach, when we look at it at night, many kilometers. How long does it take to fly to the moon?

## Earth's distance from the moon

The average distance from the Earth to the Moon is 384 399 km.

We say average because the moon’s orbit is not circular, but elliptical, which means that the distance between the Earth and the Moon is changing. At perigee - the closest point to the Earth - the distance is 363,104 km, at the apogee - the most distant point - 405,696 km.

So, we know the distance, so to find the time for which you can reach the moon, you only need to divide it by speed. Guided by this fact, we get:

- On foot to the moon to go 9 years (and will have to go continuously at a speed of 5 km / h).
- By car (if you take the average speed of 100 km / h and, again, do not make stops), the moon can be reached in 160 days.
- The plane (average speed of 800 km / h) will fly for 20 days.
- A modern Apollo-type spacecraft will be able to reach the moon in three days.

As you can see, the path is not long, and not everyone is able to withstand so much time of continuous flight, while it is worth considering that the flight would have cost a fabulous amount of money.
