Features:

	Users can add and stellar bodies to the system and supply mass, 3D positional, velocity and acceleration initial conditions.
	Users can customize objects via the stellar body editor to simulate: binary stars planets moons comets satellites
	Users can change the zoom factor, look from and look to perspective settings.
	Gravity computations are performed using the universal gravity equation: F = G * m1 * m2 / ( r * r), where F is the force (in N) acting between two bodies of masses m1 and m2 (in kg) separated by a distance of r km G is the Universal gravitational constant.
