spaceage.js

// Given an age, 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

// info: for example if someone is 1,000,000,000 seconds old, you should be able to say that they're 31.69 Earth-years old.


// todo: Create a function spaceAge that takes two arguments, a number of seconds and a planet. The function should return your space age on that planet.
