Orbiting planet and orbiting electrons in stable atoms.
No, there are circular movements just about anywhere: planets, moons and stars rotating, planets orbiting their stars, moons orbiting their planets, and stars orbiting their galaxies, often in orbits that are fairly circular, etc.
Electron
it is when earth stops orbiting
The Centrifugal force.
The tangential velocity is equal to the circumference of the orbit divided by the time taken to go round once. For the Earth that is 2pi time 149.6 million kilometres divided by 365.25 days, which comes to 2.57 million km per day or 30 km/sec.
Mercury and Venus take less time to complete one orbit of the sun, since they are closer to the sun. They have less distance to travel, and are orbiting at a greater tangential speed.
The answer depends on what information, if any, you have. If your question is in the context of space walks near earth-orbiting stations, you could have gyroscopes that measures your movement. Distance is easily measured, especially with laser range-finders, Change in distance is velocity and so on.
Phoebe is one of the moons of Saturn. See related link for more information.
If you observe an object in an elliptical orbit around something, AND you know the mass of the orbiting object AND the size of the orbit, you can calculate the mass of the object at the center (more precisely, at one of the foci) of the orbit. We observe several stars orbiting the super-massive black hole at our galactic center. We can calculate their mass based on the light they give off, and we can measure their orbits over time. From this, we can calculate the mass of that black hole.
Polar Orbiting.
That is the MESSENGER. See the related link listed below for more information:
Yes, the equation p2 = a3, where p is a planet's orbital period in years and a is the planet's average distance from the Sun in AU. This equation allows us to calculate the mass of a distance object if we can observe another object orbiting it and measure the orbiting object's orbital period and distance.
There are no rings orbiting Mercury
while the earth is orbiting the sun the moon is orbiting the earth
yes their is moons orbiting uranus
No, it is orbiting our Earth, which is orbiting our Sun.
