# Create a SolarSystem class with an @planets instance variable.
# Create an initialize method which should take a collection of planet names and store them in an @planets instance variable.
# Create a method that adds a planet to the list (not using user input).
# Create a method which will return, not print, a list of the planets as a String.
# Write code to test your SolarSystem
# Modify SolarSystem's initialize method to take a list of hashes where each planet is sent as a hash with at least 5 attributes.

# Define the class
