# Space Age Given an age in seconds, calculate how old someone would be on: - Earth: orbital period 365.25 Earth days, or 31557600 seconds - Mercury: orbital period 0.2408467 Earth years - Venus: orbital period 0.61519726 Earth years - 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 Earth-years old.

You can run the test script for the exercise by executing the command `prove . --exec=perl6` in the exercise directory. You can also add the `-v` flag e.g. `prove . --exec=perl6 -v` to display all tests, including any optional tests marked as 'TODO'. ## Source Partially inspired by Chapter 1 in Chris Pine's online Learn to Program tutorial.
