The child asked the postal department - If I want to send a letter to Mars, how much will it cost? Royal Mathematics has created this calculation with NASA's cooperation in the United States space agency.
The postal department says, sending a letter of normal weight to the Red Planet will cost approximately seventeen thousand dollars. The distance of Mars from this planet is about 55 million kilometers.
Imagine, after receiving this estimate, what was the reply of the child Oliver to the postal department? Oliver's surprise - so many stamps! 'Wow! So much money! That's why a lot of sticks!
Oliver's mother said that her child is always very curious. 'He is very interested in the heavens, the stars, and the stars.'
