The total energy of a body in a circular orbit determines the stability of the orbit. If the total energy is negative, the orbit is bound and the body will continue to orbit indefinitely. If the total energy is positive, the orbit is unbound and the body will eventually escape the gravita...
In a circular motion, the satellite remains at the same distance above the earth’s surface; its radius of the orbit is fixed, and its speed remains constant. 5. What is energy? All things around us change, grow, or move due to energy. Simply put, energy is the ability to do things...
The energy of a test particle orbiting a Schwarzschild black hole is quantized owing to the quantization of the angular momentum. For smallest stable circular orbit, the excitation energy is found to resemble closely the expression for the temperature of the Hawking radiation. This result is ...

A satellite in geostationary orbit(GEO)—a circular orbit around 36,000 km above the Earth—is exposed to the Sun for more than 99% of the time during a whole year. This allows it to produce green energy 24/73. 在轨的光伏发电不会受到夜幕降临的限制。地球静止轨道是一条距离地球约3.6万...
We consider the behavior of the innermost stable circular orbit (ISCO) in the magnetic field near "dirty" (surrounded by matter) axially-symmetric black holes. The cases of near-extremal, extremal and nonextremal black holes are analyzed. For nonrotating black holes, in the strong magnetic fiel...
The authors propose a dual-energy approach to reduce cone-beam artefacts in a circular orbit cone-beam computed tomography (CT) system. When there exist multiple dense structures within a large cone angle, two-pass algorithm is ineffective for reducing cone-beam artefacts because high-density ...
This paper presents a generic, three-dimensional semi-analytical model that outputs the quantity of solar energy for a given circular orbit and solar power farm position at the beginning of a pass. The model extends previous studies by including new phenomena such as the Earth’s oblateness, ...
