In increasing order it looks like ellipse , parabola , then hyperbola, but I am not 100 percent sure. Can someone confirm or deny this?
The three types of non-circular orbits are elliptical, parabolic, and hyperbolic. Each of these orbits has a different shape and path around the central body.
In a circular orbit, the distance between the orbiting object and the central body remains constant. In non-circular orbits, the distance changes throughout the orbit, resulting in a different shape and path.
The type of non-circular orbit an object has is determined by its velocity and the gravitational force of the central body. Objects with higher velocities and/or less gravitational force will have more elliptical or hyperbolic orbits, while objects with lower velocities and/or more gravitational force will have more parabolic or circular orbits.
Yes, objects in non-circular orbits can transition into a circular orbit if they experience a change in velocity or gravitational force. This can happen through external forces, such as the gravitational pull of other objects, or through internal forces, such as propulsion systems on the orbiting object.
Satellites, comets, and some planets have non-circular orbits around their central bodies. For example, comets have highly elliptical orbits around the sun, and some satellites have parabolic or hyperbolic orbits around the Earth.
