# How long to fly to the moon?

It's no secret that people have long dreamed of flying inspace - unexplored, vast spaces fascinate and beckon, however, space tourism has not yet become a mass industry. Why is that? Yes, because to get to another planet is not so easy. Even to the moon, which, it seems, is a stone's throw away, when we look at it at night, many kilometers. How long does it take to get to the moon?

## Distance from Earth to the Moon

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

We say the mean, since the Moon's orbit is notcircular, and elliptical - this 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 apogee - the most remote point - 405,696 km.

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

- On foot to the moon go for 9 years (and 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 stop) to the moon can be reached in 160 days.
- The aircraft (an average speed of 800 km / h) will reach 20 days.
- A modern spacecraft such as Apollo can reach the moon in three days.

As you can see, the road is not close, and it is not enough for each person to sustain such a long time of continuous flight, and it should be taken into account that the flight would cost a fabulous amount of money.
