What is the circumference of the Earth? How far around is the Earth?\n\nThe average radius of the Earth is 3,959 miles (6,374 kilometers).\nThe equitorial diameter of the Earth (distance from one side of the Earth to the other at the equator) is about 7,926 miles.\n\nThe ratio of the circumference to the diameter of a circle (circumference/diameter) \nis written as the symbol pi. \nPi is approximately 3.141592.\n3.14159265\n3.1415926535\n\nTherefore, to determine the circumference from the diameter given above:\nequitorial diameter x 3.141592 = equitorial circumference\n| |\n7,926 x 3.141592 = 24,900\n| |\nThe earth has a circumference of approximately 24,900 miles.\n\nMore precisely the circumference of the earth\nat the equator is 24,902 mi / 40,076 km. \n\n------------------\n\nHow fast would you have to travel to see the sun set twice, \nor outrun the shadow of the setting sun?\n\nSince the sun "travels" once around the earth every 24 hours, \nwe can get the speed by dividing the circumference of the earth by 24:\n\nmiles divided by hours\n| |\n24,900 / 24 = 1,038 miles per hour\n\n....\n\nA RATIO of a to b can be expressed in three ways:\n1. a : b\n2. a / b\n3. a ÷ b

The earth rotates about its axis.  Obviously at the poles, there is no speed to the rotation at all.  At the equator, the circumference of the earth is about 25,000 miles and it rotates once per 24 hours, so the speed would have to be 25,000/24 = 1041.67 mph.  Depending on where you are between the equator and the pole, you'll get a speed of between 0 and 1041.67 mph.

First ... assume an average diameter (or radius) for the planet.\n\nThe average radius normally given is 3963.1 miles (6378 km).\n\nCircumference of a circle = 2 * pi * r = pi * d\n\nCircumference = (2) * (3.14159) * (3963.1) = 24900.9 miles\n... which is approximately 40074 km.

Earth's average distance from the sun is a little bit under 93 million miles. The closets the Earth gets to the sun is about 90 million miles and the farthest is about 96 million miles.

The Earth is rotating at about 1040 mph (~1670 kph) at the equator. The speed decreases relative to your distance to the (axial) poles, where it is effectively 0. \n\nTo find out the rotational speed where you live, simply multiply the equatorial rotation speed above by the cosine of your latitude.

The earth's approx circumference at equator is 24,800 miles.  It takes about one day for it to spin around once.  So, at the equator one would be zipping right along at approx 1,000mph.  It gets slower the further north or south of the equator you go since the "circle" of latitudes gets smaller.  So, do we move fast? We do, but since we are part of the gravity well created by the earth, its spin is our frame of reference and relative to us we are not accelerating out of it.  Gravity and accelerated motion are covariant (thanks to Einstein) and an internal observer cannot tell one from the other.  Just like going along in a car.  If the car could travel extremely smoothly enough and you could not see any external input--like out the windows, unless it changed direction or speed i.e. its velocity by undergoing acceleration, you would never know you were moving. Think about it you can only really tell you're moving along by the road vibrations in the vehicle and by seeing things going by outside the windows.  You only feel "moved" if it turns or speeds up/brakes.

doesnt it go all the way round ?\n\nThe equator is an imaginary circle drawn around a planet (or other astronomical object) at a distance halfway between the poles. The equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. The latitude of the equator is, by definition, 0°. The length of Earth's equator is about 40,075.0 km, or 24,901.5 miles.\n\n \nThe equator is one of the five main circles of latitude based on the relationship of the Earth's rotation and plane of orbit around the sun. Additionally, the equator is the only line of latitude which is also a great circle.\n\nThe Sun, in its seasonal movement through the sky, passes directly over the equator twice each year on the Vernal and Autumnal Equinoxes, which occur in March and September respectively. At the equator, the rays of the sun are perpendicular to the surface of the earth on these dates.\n\nPlaces near the equator experience the quickest rates of sunrise and sunset in the world, taking minutes. Such places also have a relatively constant amount of day/night time on every day throughout the year compared with more northerly or southerly places.

G'day Dragon Warrior,\n\nThank you for your question.\n\nThe diameter of the earth in miles is 7,296 miles at the equator and 7,900 at the poles.\n\nI have attached sources for your reference.\n\nRegards

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.

depends.....at the equator, from the surface to sea level, it is 6,378.135 km. from the centre to the north or south pole, at sea level, it is 6,356.750 km. remember, both of those are to sea level, and they differ because the world is not a perfect sphere.

The Earth's circumference at the equator is 24,901.55 miles. Since the Earth rotates, it bulges outward at the equator, resulting in a measurement that is larger than if Earth did not rotate. Also, since it bulges at the equator, it contracts at the poles, resulting in a much smaller measurement than the equator: 24,859.82 miles.

Approximately 93,000,000 miles.  The distance varies because our orbit is not perfectly circular.

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.

At the Equator it is 7,926 miles to the Earth's core. To find the distance to the core from other locations on earth you find the circumference at the location and divide that distance by 3.14
