For any body in a closed orbit around another body, the farther apart the two bodies are, the slower the satellite moves in its orbit.. When the Space Shuttle is in "low earth orbit", it moves faster than the Moon is moving in its orbit. A satellite in an elongated orbit, that spends some of the time close to the earth and some of the time farther away, moves fastest at its lowest altitude, and slowest when it is furthest away.

What is geosatelite?
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time.
What are sun synchronous satellites?
A sun-synchronous orbit is one that places a satellite over a given location at the same mean solar time on successive orbits. This is accomplished by tuning the orbital altitude and inclination. The object is to have the same solar illumination angle at each approach, with the same orbital motion (ascending, descending). This is useful for surface observations, as with weather or spy satellites.
Why There is no work done when satellite rotate around earth?
With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 km). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth.At the correct orbital velocity, gravity exactly balances the satellite's inertia, pulling down toward Earth's center just enough to keep the path of the satellite curving like Earth's curved surface, rather than flying off in a straight line.
How long does it take to build a satellite?
The time it takes to put together a satellite varies on the size and structure of the satellite. A simple satellite could be put together in a couple of months, where a large science mission could take ten or more years.
Why does a geosynchronous satellite not trace a path over the surface of Earth?
A geostationary orbit achieved by being in a location where the satellite's orbital period is 24 hours. This means the satellite is about 36,000 km (22,000 miles) above the Earth's surface. All orbits must therefore be over the equator. Every orbit around the earth looks like a circular (or elliptical) ring whose center (or one foci) is at the center of gravity of the Earth. An orbit exactly above the equator is one such orbit, but any orbit can be tilted as long as the center (or focus) stays at the Earth's center and the whole orbit is flat like a disk. On various NASA maps this makes the orbit look like a sinewave, but on a globe it stays a flat circle (or ellipse). On "Star Trek" I have seen errors a number of times on "Geostationary orbit over the North Pole", well you can't do that. Likewise, a "Lunar-stationary orbit" is impossible for a spacecraft, since Earth itself is already IN THE STATIONARY ORBIT POSITION! Remember that a geostationary orbit looks like it is always over the same spot on the Earth (or other body). If you were on the Moon, the Earth would be in the same position in the sky at all times.
How does a satellite get into the exosphere?
It has to be carried there by a rocket, which takes it to the required altitude and orbital speed.
What is the approximate orbital altitude of a Polar Orbiting satellite?
870 km is its altitude according to NASA (answred bt divyansh tiwari)
What is the orbital length of prospero satellite?
The Prospero satellite, launched in 1971, has an orbital period of approximately 100 minutes. It orbits Earth at an altitude of about 1,000 kilometers. The specific orbital length can vary slightly due to its elliptical orbit, but it generally completes about 14 orbits per day.
What would be the orbital speed and period of a satellite in orbit 1.44 times 10 to the power of 3m above earth?
The orbital speed would be approximately 7.63 km/s and the period would be approximately 95.59 minutes for a satellite orbiting Earth at an altitude of 1.44 x 10^3 m. These values can be calculated using the formula for orbital speed (v = √(GM/r)) and the formula for orbital period (T = 2π√(r^3/GM)), where G is the gravitational constant, M is the mass of Earth, and r is the altitude of the satellite above Earth's surface.
What does speed affect orbiting altitude?
Speed affects orbiting altitude because the balance between gravitational pull and the orbital velocity determines a satellite's position in orbit. A higher speed allows a satellite to maintain a stable orbit at a lower altitude, as the increased centrifugal force counteracts gravity more effectively. Conversely, if the speed decreases, the satellite must move to a higher altitude to maintain a stable orbit, as the reduced centrifugal force would cause it to fall back toward the Earth. Thus, the orbital speed and altitude are intrinsically linked through gravitational dynamics.
Which could cause a satellite to descend low enough that it burns up in Earth and atmosphere?
A satellite can descend low enough to burn up in Earth's atmosphere due to several factors, including atmospheric drag, which increases as it loses altitude, and a decrease in its orbital velocity. Additionally, events such as the malfunction of onboard systems, loss of propulsion, or collision with space debris can alter its trajectory. Over time, the effects of gravitational perturbations and solar activity can also contribute to its orbital decay. When the satellite reaches a certain altitude, the intense heat generated by atmospheric friction can cause it to disintegrate.
What does the speed of a satellite depend on when orbiting earth?
The speed of a satellite orbiting Earth primarily depends on its altitude and the gravitational pull of the Earth. According to Kepler's laws of planetary motion, a satellite in a lower orbit must travel faster to counteract the stronger gravitational force compared to one in a higher orbit. The relationship can be expressed using the formula for orbital speed, which shows that speed decreases as altitude increases. Additionally, the mass of the Earth affects this gravitational force, but it remains constant for all satellites orbiting the planet.
What is the space orbital?
A space orbital refers to the path that an object, such as a satellite or a planet, follows as it moves around a celestial body due to gravitational forces. It is characterized by its shape, size, and orientation, which can be circular, elliptical, parabolic, or hyperbolic. The specific parameters of an orbital, including its altitude and inclination, determine the object's behavior and function in space exploration or communication. Understanding orbital mechanics is essential for satellite deployment, space missions, and planetary motion.
What would be the effect on the orbital velocity of satellite if mass of satellite is double?
Doubling the mass of a satellite would result in no change in its orbital velocity. This is because the orbital velocity of a satellite only depends on the mass of the planet it is orbiting and the radius of its orbit, but not on the satellite's own mass.
Is it possible to place a satellite in geosynchronous orbit at a much lower altitude?
No. To remain in orbit it needs to have a certain speed, and that speed will only match the surface speed of the earth on a certain height. To go lower it'd have to go slower, and then it'd fall.
What is orbital time period of geostationary satellite?
The orbital time period of a geostationary satellite is approximately 24 hours, specifically about 23 hours, 56 minutes, and 4 seconds. This allows the satellite to maintain a fixed position relative to a point on the Earth's surface, as it orbits the Earth at the same rotational speed. Geostationary satellites are positioned at an altitude of about 35,786 kilometers (22,236 miles) above the equator.
What is geosatelite?
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east).
