in a lower orbit will be bigger
Energy in Orbit is the total amount of energy required for an object to maintain a circular orbit around another object, such as a planet or a star. This energy includes both the kinetic energy of the object as well as its gravitational potential energy.
The formula for calculating Energy in Orbit is E = -GmM/2r, where G is the gravitational constant, m is the mass of the orbiting object, M is the mass of the central object, and r is the distance between the two objects.
Energy in Orbit is important because it determines the stability and trajectory of an orbiting object. If an object has insufficient energy, it will not be able to maintain its orbit and will eventually crash into the central object. On the other hand, if an object has too much energy, it will escape the orbit and fly off into space.
Satellites in orbit around the Earth require a specific amount of energy to maintain their orbit. If they have too much energy, they will drift away from their intended orbit. If they have too little energy, they will fall back towards Earth. Calculating and monitoring the Energy in Orbit of satellites is crucial for their proper functioning.
Yes, Energy in Orbit can be changed by altering the velocity or distance of the orbiting object. This can be done through rocket propulsion or by using the gravitational pull of other objects in the vicinity. However, any changes to the Energy in Orbit will also affect the object's orbit and trajectory.
