The main objective of this program is the calculation of the orbit and the motion of the planet around the star with use of weight, orbital velocity of the planet and average distance from the star to the planet. The amount of planets is unlimited. The application can calculate:
-The shape of the orbit (ellipse, parabola or hyperbole);
-Orbital speed;
-Semi-major and semi-minor axes;
-Eccentricity;
-The approximate radius of the planet;
-Period;
-Acceleration of the planet;
-Minimum and maximum speed;
To calculate the physical quantities of orbit and form were used numerous formulas.
In random mode, mass, orbital velocity and the average distance is generated programmatically
