Project #3 A clock

Description

I want to imitate the orbit of the comet around the solar system to make a clock. In reality, the clock is basically round. In order to "draw" the orbits of the planets, I used ARC and Map to draw a basic sector, which can change according to time. Then I draw the boundaries with stroke. Next I used Nofill to cancel the filling inside the arc to draw the basic orbits. In order to make the Angle change and data input more convenient, I used angleMode(DEGREES) at the beginning. I also tried to make an alarm clock with if else, which would remind me to get ready for class whenever classes started at 9 o 'clock. At other times I would be reminded to listen to teachers and do homework. But I didn't find out the way to draw a comet in front of the orbit.
