Question	Answer
When does the initialize method run? What does it do?	Initialize accepts parameters and keeps track of some data as part of their state, to define new instance variables of the class it refers to.
Why do you imagine we made our instance variables readable but not writable?	So they remained unchangeable by the user.
How would your program be different if each planet was stored as a Hash instead of an instance of a class?	Each method would have to receive the whole hash to process data and it would require more lines of code to fill all the planet parameters, for example.
How would your program be different if your SolarSystem class used a Hash instead of an Array to store the list of planets?	the way to store and retrieve data would change, and it would require a more nested data structure.
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?	Yes. Class Planet handles the creation of instances of planets and class SolarSystem handles the responsibility of creating a solar system and
How did you organize your require statements? Which files needed requires, and which did not? What is the pattern?	the files that needed require were the main.rb file and the planet_test.rb . I organized 'require' statements by adding them to the files where I used classes created on the files required.
