# Space Age
|
||
|
|
|
||
|
|
Welcome to Space Age on Exercism's C++ Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Given an age in seconds, calculate how old someone would be on:
|
||
|
|
|
||
|
|
- Mercury: orbital period 0.2408467 Earth years
|
||
|
|
- Venus: orbital period 0.61519726 Earth years
|
||
|
|
- Earth: orbital period 1.0 Earth years, 365.25 Earth days, or 31557600 seconds
|
||
|
|
- Mars: orbital period 1.8808158 Earth years
|
||
|
|
- Jupiter: orbital period 11.862615 Earth years
|
||
|
|
- Saturn: orbital period 29.447498 Earth years
|
||
|
|
- Uranus: orbital period 84.016846 Earth years
|
||
|
|
- Neptune: orbital period 164.79132 Earth years
|
||
|
|
|
||
|
|
So if you were told someone were 1,000,000,000 seconds old, you should
|
||
|
|
be able to say that they're 31.69 Earth-years old.
|
||
|
|
|
||
|
|
If you're wondering why Pluto didn't make the cut, go watch [this YouTube video][pluto-video].
|
||
|
|
|
||
|
|
Note: The actual length of one complete orbit of the Earth around the sun is closer to 365.256 days (1 sidereal year).
|
||
|
|
The Gregorian calendar has, on average, 365.2425 days.
|
||
|
|
While not entirely accurate, 365.25 is the value used in this exercise.
|
||
|
|
See [Year on Wikipedia][year] for more ways to measure a year.
