Technically, a satellite in free-fall (and orbit is a special case of "free-fall") is effectively weightless. What we call weight is the force of the RESISTANCE to gravity; I "weigh" 220 pounds because I an standing on the Earth.
The satellite has its own mass, and this can be anything from "tiny" to "enormous".
The orbit helps the satellite go into orbit.
The mass of a satellite does not affect its orbit. The orbit of a satellite is determined by its speed and the gravitational pull of the object it is orbiting around, such as a planet. The mass of the satellite itself does not play a significant role in determining its orbit.
If a satellite is placed in an orbit at a distance from the center of the Earth equal to twice the Earth's radius (i.e., at a height equal to the Earth's radius), its weight would be reduced due to the inverse square law of gravitation. The gravitational force acting on the satellite at this distance is one-fourth of that on the surface, meaning it would weigh 25% of its weight at the Earth's surface. Hence, if its weight at the surface is ( W ), at this orbit it would weigh ( \frac{W}{4} ).

A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
The repetitivity and revisit of satellite orbit refers to the time elapsed between observations of the same point on earth by a satellite. It usually depends with the target location, the orbit of the satellite and the swath of the sensor.
The very first satellite put into orbit was the Russian satellite Sputnik put into orbit on October 4th, 1957.
YES As height increases, speed of satellite decreases.
Yes, the Archimedes principle applies in a satellite moving in a circular orbit. The principle states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object. In the case of a satellite in orbit, the principle still holds as the satellite is displacing the atmosphere and experiences a reduced weight due to its orbital motion.
By definition planets orbit a star and satellites orbit a planet. Therefore there are no satellite planets.
The plane of a satellite's orbit must include the center of the earth.
In 2005 a satellite went into orbit around Venus.
