Solar System Project

Let's make a planetary system!

Baseline

• Create a Planet class with a name attribute. You should be able to instantiate a new Planet object with an associated name.

Wave 1

Primary Requirements

• Give your Planet class some additional properties like diameter, mass, number of moons, and any other properties you think a planet should have.
• You should be able to create many different planet objects with different properties, like Mercury, Venus, Earth, Mars, Jupiter, etc.

Optional Enhancements

• Give each planet a rate of solar rotation
• Give each planet a @distance_from_the_sun attribute
• Write a new program that asks for user input to query the planets using the Planet class you have created:
  • First, ask the user to select a planet they'd like to learn about.
  • Present the user with a list of planets from which they can choose. Something like:
    • 1. Mercury, 2. Venus, 3. Earth, 4. Secret Earth, 5. Mars, 6. Jupiter, ... 13. Exit
  • Provide the user with well formatted information about the planet (diameter, mass, number of moons, primary export, etc.)
  • Then ask the user for another planet.

Wave 2

Primary Requirements

• Create a SolarSystem class that has an attribute planets that has zero to many Planet instances. To create the Planet associations, your SolarSystem should:
  • Have a method that adds a single planet to your solar system
  • Have a second method that adds an array of planets to the existing array of planets
• Update your initialize in the Planet class to accept a hash rather than individual parameters
• Use a default value attribute in at least one method in your Planet class

Optional Enhancements

• If you haven't already, add a @distance_from_the_sun attribute to your Planet. Using this data, add a method to your SolarSystem which will calculate the distance between any two planets provided (assuming planets are in a straight line from the sun)
• Give your solar system a formation year (in earth years).
• Define a method that returns the local year of the planet based on it's rotation since the beginning of the solar system
