It depends on the season. The current average lengths are:\nWinter: 88.994 days\nSpring: 92.758 days\nSummer: 93.651 days\nAutumn: 89.842 days \n\n(These values change slowly over time, as the position of the perihelion of Earth's orbit changes.)\n\nThe differing lengths of the season enabled ancient Greek astronomers to accurately measure the eccentricity of Earth's orbit as far back as the 2nd century BC.

It rotates around its axis every 23 hours and 56 minutes. The circumference of the equator is 40,075 km. That means the equator is moving at a speed of 1674 km/h. The atmosphere moves with the ground, which is why we're not blasted into space by 1000 mph winds.\n\nIt revolves around the Sun every 365.24 days ata radius of about 150 million kilometres. That makes its orbital speed 108,000 km/h.

Our motion around the sun is only one revolution per year, so that doesn't show much change on a daily basis. The rotation of the sun brings new details into view. The speed of rotation varies with position on the sun - things at the sun's equator go around once every 25 days, but it's only spinning once every 36 days at its poles. \n\nSome features on the sun, solar flares for example, come and go in a few hours or less, but sunspots tend to persist for many days, long enough  so you can watch them as the sun's rotation caries them around.

That depends on where on Earth you are standing. At the poles, the Earth hardly spins at all, but as you travel towards the equator, the rotational speed picks up. This makes sense -- as the circumference of a circle increases, a single point along it has to travel faster to complete a revolution in the same amount of time. \n\nThe rotational speed of the Earth at the equator is about 1,038 miles per hour. The atmosphere at the equator is also slightly thicker due to rotation, and you weigh slightly less. At mid-latitudes, the speed of the Earth's rotation decreases to 700 to 900 miles per hour. \n\nIf the Earth were to stop spinning suddenly, the atmosphere would still be zipping along nicely at around 1,000 miles an hour. As a result, everything not attached to bedrock would pretty much be scoured clean. \n\nThe circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour. \n\nMultiply by cosine of your latitude to see how fast the Earth is rotating where you are. \n\nHope you get an A if you are doing a science project haha.  Or hope you learned something :)

The rotation of the Earth on it's axis does not vary, but the speed of orbit about the sun does, to a tiny degree.  Earth is slightly closer to the sun in the winter months, thus orbits slight faster (and I mean infinitesimally faster).\nAs far as speed- Earth is about 25,000 miles in circumference, if orbits exactly once a day (24 hours) to the speed is a little over 1,000 miles an hour.\nEarth is 93 million miles from the sun, on average-this means the total orbital distance is 93 million X 2 X 3.14 = 584 million miles.  It goes this far in exactly 1 year-364.8 day or (364.8 X 24) 8733 hours. So, 584 million/8733 = about 66,500 miles/hour.  I just checked online and it says about 65,000, so there ya go

Lets see now, Earth rotates aproximately once every 24 hours, thats one over 60 x 60 X 24, thats one over 86400 rotations per second. All the time we are doing that, consider this, we are also going around the sun at aproximately 66500 miles per hour.

The Earth orbits the sun at an average speed of 67,000 mph in a counterclockwise direction when viewed from above it's North Pole.

The Earth rotates once in 24 hours, and its (equatorial) radius is 3,963 miles (6,378 km). As with the Moon, the rotational speed starts at zero at either geographic pole and increases as you head toward the equator, where it reaches its maximum of about 1038 mi/hr (1669 km/hr). At 45 degrees north or south latitude, the rotational speed is about 0.7 of this maximum speed.

hold on here, this isnt a short answer - \n    the Earth is on average 92Million miles from the sun, times pi for the circumforance and its roughly 290Million miles around.  divided by 365 for the number of days, the earth travels some 790,000 miles on one day, ya thats high on the odometer.  distance in one day divided by 24 hours comes to 33,000 MPH, now i did this on my computer but it does seem right, \n\nNow part 2, hang on here, big numbers ahead, the Solar System wihich Earth belongs to is roughly 26,000 Lightyears from the galactic core, (which has a Supermassive Black hole as heavy as 6 Trillion suns).  it take a quarter of a Billion years (250,000,000) for our solor system to complete one revolution around the galaxy. The circumferance could be some 80,000 Lightyears,  though i am not sure how to calculate the speed of the solar system.

For one thing, it takes the earth 24 hours to complete one full rotation, and the earth has circumference of roughly 24,000 miles, which means the speed of its rotation is appx. 1000 mph...\n\nSo if we did not have a protective atmosphere as we do, winds could be up to 1000 mph. Fortunately we do, so the winds we do experience are usually negligible...

We know that the Earth is 360 degrees(as the Earth is a sphere). Now the Earth takes about 24 hrs to complete a rotation or 360 degrees. Therefore in 1 hour, it will travel 15 degrees. But some times countries are so small that they don't even occupy 15 degree area. So its half - 7.5 degrees is taken into consideration. The main purpose of taking all this trouble is to make the calculation of time easier.

The mean radius is 6371.0 km.  The radius at any latitude is equal to that times the cosine of the latitude.  The Earth turns once on it's axis in 23 hr 56 min 4.0989 sec, or 23.93447 hrs.\n\nIt takes that long to travel 2(Pi)(6371)(cos(lat)).  Divide that distance by the time above and you're in the ball park (neglecting the difference in polar and equatorial radii).\n\nNote: The figure given for the Earth's rotation is correct according to Astrophysical Data: Planets and Stars.  The 24-hour day is measured from noon to noon - in relation to the Sun.  The Earth kind of rolls around its orbit, so after it has turned thru one rotation it has also moved along its orbit.  It has to turn for another 53.9 sec past the full rotation for the Sun to be back to due south again.

Man has been tracking time for tens of thousands of years.  Beyond the daily cycle of the sun, what is there to use to track time?  The moon and the stars.\n\nIt takes the moon about 29 1/2 days to go around the Earth, about a month.  The word "month" is derived from the same root as the word "moon."\n\nThe Earth revolves around the Sun over the course of a year, but if you don't know that, it appears that the entire universe of stars revolve around the Earth and Sun.  It takes about 365 1/4 days for the stars to go back to where they started, and that makes a year.\n\nSo the moon revolves around the Earth about 12 times a year, and thus we have 12 months.\n\nBut actually it takes fewer than 360 days for the moon to go around the Earth 12 times.  The months had to be lengthened so that 12 months match one year.  (Other societies used lunar calendars, which kept the month based on the moon's cycle.)  30 days per month would still make the year too short, and 31 days per month would make the year too long.  Thus we have some months 30 days and others 31 (and one other).\n\nEven still, the length of the year doesn't exactly match the revolution of the Earth around the Sun, so we make adjustments.  Every four years, we add a day to February.\n\nAnd still it's not perfect, so every 400 years, we don't add that day to February.\n\nAs for why February starts with only 28 days is not known for sure.  There have been different explanations, but it comes down to someone a long time ago making a pretty odd decision.

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".

Mean distance from earth149.6×10^6 km or (92.95×10^6 mi)\nIt would take about 8.31 minutes at the speed of light to go from earth to sun.
