Well, the earth revolves around the sun once a year, the earth rotates on its axis once a day, and the moon revolves around the earth about once a month.  Most of the apparent movement of the moon and sun across the sky is due to the earth rotating.  Some of the movement of the moon is due to the moon revolving around the earth.  But it takes about 28 days for the moon to travel around the earth, and it only take one day for the earth to rotate on it's axis, so you see the relative effect.

First, the Earth is rotating at about 1,600 km an hour. Second, a full Earth orbit takes 365.242 Earth days, or about 8,766 hours. We can find the "circumference" of Earth's orbit by taking the radius (about 150,000,000 km) and multiply by 2pi, giving us about 940,000,000 km. Rate equals distance over time, so (940,000,000 km)/(8,766 hours) equals about 107,300 km per hour. \n \nSo far: In only the solar system, Earth's maximum speed is about 109,000 kmph and minimum speed is about 105,500 kmph.\n\nHowever, the solar system is orbiting around the center of the Milky Way galaxy. We are about 2/3 of the way out on the 100,000 light-year disc, or about 624,394,875,000,000,000 km. It takes us 200 million years to orbit. I'll shorten this and not completely lay out the math..................\n\nroughly 2,240,000 kmph.\n\nAdd this with our previous number to get:\n-Earth's maximum speed: roughly 2,357,000 kmph\n-Earth's minimum speed: roughly 2,130,000 kmph\n\nBut wait: we're not done yet. The Milky Way is speeding through space towards the (relatively) near-by Andromeda Galaxy at 600km every second, or 2,160,000 kmph. Factor this in to get our final result:\n\n-Earth's maximum speed: roughly 4,500,000 kmph\n-Earth's minimum speed: roughly 197,000 kmph\n\n\nSo how does all of this confusing math relate to your question? Look at this set of data. Regardless of the Earth, the Milky Way is cruising along at roughly 2,160,000 kmph. The Earth, however, relative to the Milky Way, is moving as much as about 2,357,000 kmph and as little as about 2,130,000 kmph.\n\nSorry this is so long winded.

Earth ROTATES about itself.\nIt REVOLVES around the sun.\nThere is a difference betwen earth's ROTATION and \nREVOLUTION.\n\nROTATION takes 24 hours.\nREVOLUTION takes 365.255 days\n\nPeople say, 'the sun is up or the sun rises'.  This is conventional.  You can't expect people to speak technically and scientifically.  A scientist won't speak like that.\n\nthe sun is fixed in its position and it rotates about itself.  only the earth and other planets are rotating about themselves and revolve around the sun.  Sun is the centre of gravity for them.  If they don't ROTATE around themself, they will be attracted by the sun and they will become the food for the sun's fire.  They ROTATE only to counter-attact that gravitational force by the sun.\n\n\nExamples for u:\n\nROTATION:  Imagine a top, it rotates around itself\nREVOLUTION:Consider a circular circuit in a motor car race.\n\nEarth does these two things.

The Sun does indeed rotate. different part of sun rotates at different time. its like jupiter. \nA rigid body such as the Earth will clearly have a single rotation rate. But since the Sun is made of gas, different parts of it rotate at different speeds. Near the Sun's equator, it completes one rotation every 27 Earth days. But near the poles, it's about 31 Earth days. This is called "differential rotation".

First of, there's no force causing planets to rotate. \n\n"Most of the rotation comes from the conservation of angular momentum. The formula is L=m*w*r2 where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion. Due to conservation of angular momentum, if the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). \n\nAnyway, the bottom line is that stars like the Sun spin from the original angular momentum that was there in the solar nebula from which it formed. Not only that, all orbital motion of the planets (including the spin) is due to this orginal angular momentum."

Every morning on Mars, the Sun rises in the East, and every evening, it sinks to the West.\nSomeone got cunfused with they're information. MARS ITSELF \nRISES AND SETS IN THE EARTH'S SKIES FROM THE WEST TO THE EAST.\nThe retrograde motion is what causes MARS to shift rise and set directions in OUR SKY.\n\nFor the Sun in the skies of Mars to rise and set  in opposite horizons would mean that Mars suddenly came to a stop and started spinning backwards on it's axis.\nMars could only change its direction of planetary rotation if a planet larger than itself crashed into it with an unimaginable amount of force.\nSo no, that information is incorrect and Mars still rotates the same way around our sun.

Because it takes 24 hours for the earth to make one full rotation.

It generally takes 6-9 months. Please read the book:"The Case for Mars" by Dr. Robert Zubrin, PhD for a down to Earth nuts and bolts scientific discussion of how to put men on Mars, written for the layman. If you have any desire to learn about the future of mankind, this is it.

So earth will complete a complete rotation on its axis in 6 hrs instead of 24 hrs. So we have on average 3 hrs days & nights.It will also affect the distance of earth from sun. In nutshell the life on earth will be in danger.

Yes, as long as definitions are consistent.\n\nThe Moon rotates from west to east, the same direction that it revolves around the earth. At its equator, the Moon rotates at a speed of about 10 miles (16 kilometers) per hour. \n\nThe Earth rotates on its axis from West to East with its axis in the North/South direction.\n\nIt is sometimes thought that the Moon does not rotate, because it always presents the same face (roughly) to a point on Earth. However this is because the time it takes to complete one rotation is almost the same as the time it takes to complete one revolution around the earth; not because it does not rotate.

I would presume from other galactical planets that are further from the sun than earth that their dormant not motile state is due to the hardening of their planet crust.  Also, as you fill a tire with water and spin, it takes more energy to rotate than that without, hence, slower process at least.

It takes the Moon 27.322 days to go around the Earth once. Because of this motion, the Moon appears to move about 13° against the stars each day, or about one-half degree per hour. If you watch the Moon over the course of several hours one night, you will notice that its position among the stars will change by a few degrees.

Earth orbits in a counterclock wise direction around the sun.\nIt takes approximately 365.25 days do orbit around the sun.\nThe gravitational forces between the sun and earth and the resulting centripetal and centrufugal forces makes the earth go around.

No, Mars doesn't stop and reverse its direction in space. Mars and Earth are like race cars on an oval track. Earth has the inside lane and moves faster than Mars -- so much faster, in fact, that it makes two laps around the course in about as much time as it takes Mars to go around once. About every 26 months, Earth comes up from behind and overtakes Mars.\n\nCheck out the excellent animated graphics at this website that shows exactly what happens -->http://mars.jpl.nasa.gov/allabout/nightsky/nightsky04-2003animation.html
