part of the body‚ usually involves the torso‚ and is usually accompanied by a number of satellite nevi. Satellite nevi (or just satellites) are smaller melanocytic nevi (smaller birthmarks). When a child is born with a giant nevus‚ it is common for satellite nevi to be present at birth. It is also common for satellite nevi to appear after birth. Sometimes during diagnosis‚ doctors may use a large number of satellites to support their diagnosis of a large or giant congenital melanocytic nevus. Sometimes

How Many Satellites Are Orbiting the Earth? Satellites are tracked by United States Space Surveillance Network (SSN)‚ which has been tracking every object in orbit over 10 cm (3.937 inches) in diameter since it was founded in 1957. There are approximately 3‚000 satellites operating in Earth orbit‚ according to the US National Aeronautics and Space Administration (NASA)‚ out of roughly 8‚000 man-made objects in total. In its entire history‚ the SSN has tracked more than 24‚500 space objects orbiting

ENERGY CONSIDERATIONS IN PLANETARY AND SATELLITE MOTION Consider a body of mass m moving with a speed v in the vicinity of a massive body of mass M‚ where M >> m. The system might be a planet moving around the Sun‚ a satellite in orbit around the Earth‚ or a comet making a one-time flyby of the Sun. If we assume that the body of mass M is at rest in an inertial reference frame‚ then the total mechanical energy E of the two-body system when the bodies are separated by a distance r is the sum
