The total energy of a satellite doesn't change. At its closest approach to the
planet, it has the most kinetic energy and the least potential, whereas at its
furthest retreat from the planet, it has the least kinetic energy and the most
potential. But their sum ... the satellite's total mechanical energy ... is always
the same.
(It may gain heat energy when the sun is shining directly on it, and lose it
when it's in the planet's cold shadow, but neither of those changes affects
its orbit.)

Is a asteroid's orbit elliptical?
Yes. They orbit the Sun and as per Kepler's first law they follow an elliptical path. Do note that a circular orbit is a special type of elliptical orbit.
What year did a satellite go into orbit around venus?
In 2005 a satellite went into orbit around Venus.
A satellite is 200 miles above the earth It has a mass of 150 kg If the mass of the satellite were tripled?
You don't really have a question here. If the satellite is in orbit, the mass is essentially irrelevant; it wouldn't change the speed of the orbit or the altitude. A larger satellite mass WOULD HAVE required more fuel and more energy to LAUNCH it, but once in orbit, it will stay there. The only exception would be an exceptionally large, light satellite. There is still some minuscule traces of atmosphere at 200 miles, and a large, light satellite would be slowed by air friction much more than a small dense satellite would. This is what caused the "ECHO" satellite - essentially a silvered mylar balloon inflated in orbit as a primitive reflector comsat - to deorbit.
What happens to it's orbits if a satellite is in orbit around the Earth and it slows down?
If the speed of a satelite orbiting earth were to decrease, it's orbit would come closer to the earth, and eventually it would fall to the Earth. Space administratioins(like NASA) use calculus and whatever fancy term thay use for their math to try and make it land in a safe place. On the other hand, if it were to increase in speed, it would eventually leave Earth's orbit.
How is a weather satellite in polar orbit able to view Earths surface?
From the question, I'm guessing that when the questioner reads the term "polar orbit", he's picturing the satellite doing a little tiny circle in the sky over the North Pole. This is not an accurate understanding of the term. Remember that the center of the orbit of an artificial satellite has to be at the center of the earth. A 'polar orbit' is an orbit that covers both poles. If you picture the globe of the earth, the satellite's orbit is a circle standing up, with the satellite traveling up and down, passing over both poles in each complete revolution of the earth. As the earth rotates, every point on earth passes under the orbit, and sooner or later, every point on earth will be visible from the satellite.
At what part of an elliptical orbit does a satellite have the greatest speed the least speed?
in the orbit of a planet there is a point called perihelion which is closest point to the sun and aphelion which is furthest from the sun . Moment of a planet in it's elliptical orbit reaches it's maximum in perihelion
When a satellite in an elliptical orbit approaches closer to the planet it is orbiting its kinetic energy is decrease or increases?

What is an elliptical satellite?
An elliptical satellite is a type of satellite that orbits Earth in an elliptical path, meaning its distance from Earth varies throughout its orbit. This results in the satellite moving closer to and farther from Earth as it completes its orbit. Elliptical satellites are commonly used for applications like communication and remote sensing.
Where does a satellite in elliptical motion have the most kinetic energy?
At apapsis - when it is closest to the planet. In that case, it is moving fastest. Note that at apapsis, its potential energy will be lowest, since it is closer to the planet, while its kinetic energy will be highest. The sum of potential + kinetic energy doesn't change during the orbit.
Why does the speed of a satellite undergo change in an elliptical orbit?
The speed of a satellite changes in an elliptical orbit because the satellite moves faster when it is closer to the central body due to gravitational acceleration, and slower when it is farther away. This change in speed is necessary to balance the varying gravitational force experienced by the satellite at different points in its orbit.
A satellite in an elliptical orbit travels at constant what?
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
What is pogee?
Apogee is the point at which a satellite in an elliptical orbit is At its apogee, the satellite travels slower than at any other point in its orbit.
What is a satellite orbit?
A satellite's orbit is just the path it follows around the Earth or some other planet.Satellites' orbits can be elliptical or circular.
Does an object with high gravitational potential energy always have a low kinetic energy?
No. For example, a satellite in orbit has a lot of both.
A satellite in an elliptical orbit gains speed when it?
A satellite in an elliptical orbit gains speed when it moves closer to the body it is orbiting due to the conservation of angular momentum. This increase in speed occurs as the gravitational force from the body pulls the satellite inwards, causing it to accelerate.
The path of a satellite orbiting the earth is best described as linear hyperbolic parabolic or elliptical?
Elliptical. The satellite follows a curved path around the Earth known as an elliptical orbit, where it travels at varying distances from the planet.
What is potential energy of a satellite?
The potential energy of a satellite in orbit around a planet is due to the gravitational attraction between the satellite and the planet. It is a type of energy that depends on the satellite's position relative to the planet, and is higher the higher the satellite is from the planet's surface. Mathematically, the potential energy of a satellite can be calculated using the formula: PE = - G * (m1 * m2) / r, where G is the gravitational constant, m1 and m2 are the masses of the planet and satellite, and r is the distance between their centers.
