Create a class called Planet (e.g. https://en.wikipedia.org/wiki/Solar_System) . It has instance
variables, constructor parameters, and accessor methods for the following data:
- String name
- boolean innerPlanet
- double astronomicalUnitsFromSun
- double earthMasses
Create a method called getPlanetaryData() which returns a String in the exact format of
“Mercury is an inner planet, weighs 0.055 Earth masses, and is 0.4 AU from the Sun.” or
“Jupiter is an outer planet, weighs 318 Earth masses, and is 5.2 AU from the Sun.”, etc….
Create another method with the signature public Boolean isSimilarToEarth() which returns true
if and only if the Planet is less than 1AU from the Sun or weighs less than 15 Earth masses.
Create a Main class with a main method. The main method creates all eight Planet objects for our
solar system, calls each Planet’s getPlanetaryData() method, and also reports in one sentence for
Planet whether the Planet is similar to Earth, in the format of “Jupiter is not similar to Earth.”.
