Implement the Star class from the UML design $($provide the class definition and method implementations$).$ Take note:

a$)$The m$\_$is$\_$visible data member is used by the GUI to determine if the object will be visible at certain values ofm$\_$right$\_$ascension $($it helps to reduce the number of objects drawn if we know which ones are visible$).$ The visibility of an object depends on the observer$$s position on the earth. For our purposes, if the m$\_$right$\_$ascension value is between $6$ and $18($inclusive$),$ the object is visible.

b$)$The m$\_$is$\_$visible data member must be set to the correct value in the advance$()$ function implementation of the Star class.

c$)$Do not re$-$implement any calculations that have already been implemented.

d$)$Leave the body of the draw$()$ function empty
