Algorithm - Simulation of Elliptical Orbit

Algorithm - Simulation of Elliptical orbit

1.     Start the program
2.     Set screen size and caption
3.     Create clock variable
4.     Set x and y radius of ellipse.
5.     Starting from degree 0 ending with 360 degrees in increments of 10 degrees  calculate the (x1, y1) coordinates to find a point in the elliptical orbit.
6.     Convert degree to radians (degree * 2 * math.pi / 360)
7.     Set background color, draw center circle, ellipse and another smaller circle on the ellipse
8.     Refresh the screen every 5 clock ticks
9.     Repeat steps 4 to 8 until user quits the program
10.     Stop the program
