Solar System

Congratulations! You're submitting your assignment.

Comprehension Questions

Question	Answer
When does the initialize method run? What does it do?	The initialize method runs when I create a new instance of the Planet or Solar System class. It calls the new method and hands it a bunch of information.
Why do you imagine we made our instance variables readable but not writable?	Because the user doesn't need to (and shouldn't) change any of those instance variables.
How would your program be different if each planet was stored as a Hash instead of an instance of a class?	Manipulating the data stored in each Hash would be cumbersome and confusing.
How would your program be different if your SolarSystem class used a Hash instead of an Array to store the list of planets?	It would be a strange choice because most of the data is specific to each planet.
There is a software design principle called the SRP. The Single Responsibility Principle (SRP) says that each class should be responsible for exactly one thing. Do your classes follow SRP? What responsibilities do they have?	Hmm. I think some of the methods, or parts of methods, with input/output within the Solar System class should belong in main rather than in a class. I realized this too late. I think the planet- and solar system-related responsibilities are fairly well assigned.
How did you organize your require statements? Which files needed requires, and which did not? What is the pattern?	main has the require statements, because that is the file pulling in information from the other others. I could have had a hierarchy, where main pulled from solar_system and solar_system pulled from planet.

let your cli handle this puts-type stuff, to keep this more of a single responsibility.
