Someone once said that a human year is equal to 7 dog years.

Create a function named dogYears, that accepts the name of a planet, and the age of the dog in seconds. Your function should return the age of the dog on that planet in dog years.

• earth: orbital period 1.0 Earth years, 365.25 Earth days, or 31,557,600 seconds.

If you were told that a dog was 1,000,000,000 seconds old, you should calculate that the dog would be 221.82 Earth-years old.

You will have to format the number so that the result is rounded like the example above.
