yes the sun does do work for earth it does a whole lot it gives us light and it also gives us
something not to stare at and if you stare the sun you could damage your eyes
Another Answer
"Does sun do any work on earth?" YES, yes, yes! On Earth, all energy (except
geothermal) in all forms, was and is produced by the Sun's energy intersected
and accumulated by the surface of our planet.
And Yet Another:
OK, folks. Nice dutiful expressions of our gratitude and appreciation for all that
the sun does for us. For its light, its heat, its various forms of energy, its benefits
and benevolent bountiful sustenance of life on our planet. But "work" ? Not.
In the strict, technical sense, "work" means force acting through a distance. You
know that this is what the question is fishing for, otherwise there would have been
no reason for it to start out with "Earth orbit the sun". In a gravitational orbit, the
centripetal force doesn't act in the direction of the orbiting body's motion, so no
work is done by the force.
The core of the earth consists of an outercore of liquid nickel and iron revolving around an innercore of solid iron. The revolution of this hot metal creates a magnetic field which we call our magnetosphere. our magnetospere protects us from much of the harmful radiation that comes from the sun.
The earth only has one moon
To be exactly technical about it, the earth and sun do both revolve, around their "common center of mass".The common center of mass is the point where the pivot would have to be in order for the sunand earth to balance on a see-saw.Since the sun's mass is so much greater than the earth's mass (about 332,000 times as much),the pivot of the see-saw would be much closer to the sun. In fact, the pivot point is insidethe sun, so it appears as if the earth is just revolving around the sun. But the sun is actuallydoing a little wobble of its own, as both bodies revolve around the same point.
Cannot be done as the Earth is much older than the oldest fossils.
That's 4 times as much as going once around the Earth. The distance around the Earth is about 40,000 kilometers, or 40 million meters.
The Moon takes longer. The Earth spins once in 23 hours 56 minutes, while the Moon spins once in about 27 days.
Answer #1:The Moon orbits around the Earth because its mass is much smaller than thatof the Earth. So, the gravitational power of the Earth keeps the Moonorbiting around it. If the Moon were bigger than the Earth, we would beorbiting around the Moon, instead. All the planets of the solar system orbitaround the Sun, because it is much bigger than the planets.....===================================Answer #2:It means that the Earth and the Moon both revolve around a point betweenthem called their 'common center of mass'. That's the point where the pivotwould have to be in order for them to balance each other on a see-saw.Since the Earth has about 80 times as much mass as the moon has, the pivotwould be about 80 times farther from the moon than it is from the Earth. Theresult is that the 'common center of mass' is actually inside the Earth, andboth bodies are revolving around that point. If you're out in space watching it,it looks like only the moon is doing any revolving. But the fact is that the Earthis also doing a small wiggle around that point.
The work done on a satellite in a circular orbit around Earth is zero because the gravitational force acting on the satellite is perpendicular to the direction of motion, so no work is done to maintain the orbit.
Since the moon is revolving around the earth, it must be closer than the earth isto the sun for half the time and farther for the other half. So the moon's averagedistance from the sun must be pretty much the same as the earth's average distance.That's 149.6 million km.
Galileo initially showed using phases of the planet venus that it orbited around the sun and not the earth, this supported a new model developed by Copernicus suggesting that the earth orbited the sun and not vice versa. It had always been assumed that the moon orbited the earth. Later with the invention of Newtonian physics, a more concise model of the solar system was developed using the laws of gravity explained that the much smaller earth would orbit around the much larger sun and that the smaller moon would orbit the larger earth.
Technically, the earth and moon both revolve around their common center of mass. But since the earth has about 80 times as much mass as the moon has, their common center of mass is actually inside the earth. That's why, if you watched the motions of the two bodies from a seat located at the common center of mass, it would look to you as if the moon was revolving around you in a large orbit, whereas the earth was barely wiggling.

The Moon is in synchronous rotation with the Earth, which means it rotates on its axis in exactly the same time it takes to orbit the Earth, so one side permanently faces the Earth and the other side permanently faces away. The Moon orbits the Earth as a result of the mutual gravitational force of attraction between them.Strictly speaking, the Moon isn't revolving around the Earth per se; rather, both the Moon and the Earth are revolving around a mutual point, known as the barycenter. Because the Earth so much more massive than the Moon, the barycenter of the Earth-Moon system is actually within Earth's crust.

The moon orbits the Earth because it is closer and smaller than us.
