+# 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 31.69 Earth-years old.

+
+## No Stub
+
+This may be the first Go track exercise you encounter without a stub: a
+pre-existing `space_age.go` file for your solution. You may not see stubs in
+the future and should begin to get comfortable with creating your own Go files
+for your solutions.
+
+One way to figure out what the function signature(s) you would need is to look
+at the corresponding \*\_test.go file. It will show you what the package level
+functions(s) should be that the test will use to verify the solution.
+
+
+## Running the tests
+
+To run the tests run the command `go test` from within the exercise directory.
+
+If the test suite contains benchmarks, you can run these with the `--bench` and `--benchmem`
+flags:
+
+ go test -v --bench . --benchmem
+
+Keep in mind that each reviewer will run benchmarks on a different machine, with
+different specs, so the results from these benchmark tests may vary.
+
