+## My list numbering is wonking when calling the print_panets method in line 178. The code block is on lines 149 - 157. I'm interating over the planets array variable, calling the planet_info method on each planet instance. It seems very similar to what I did in 83 - 86. Expect for some reason the numbers are printing out at the end of the string instead of the begining.
