Orbital radius refers to the average distance between an orbiting object, such as a planet or a satellite, and the object it is orbiting. In the context of celestial mechanics, orbital radius is a fundamental parameter that determines the shape and size of an orbit.
The orbital radius of an object is influenced by the gravitational force between the two objects involved in the orbit. For example, in the case of a planet orbiting a star, the orbital radius depends on the mass of the star and the velocity of the planet. The greater the mass of the star, the larger the orbital radius, and the higher the velocity of the planet, the smaller the orbital radius.
The orbital radius can be calculated using the formula:
r = (h^2 / G * M)

Here are some key points to remember when studying orbital radius:
By mastering the concept of orbital radius, you will gain a deeper understanding of the dynamics of objects in orbit and their relationship to gravitational forces.
