What is the Diameter, in Kilometers, of the Earth's orbit around the sun?

The diameter of the Earth's orbit around the Sun is about 300,000,000 kilometers

The average distance is 238,855 miles (384,400 km). \n\nHowever, because its orbit is not circular, the distance varies between perigee (225,700 miles, or 363,300 km) and apogee (252,000 miles, or 405,500 km).

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

As far as I know 1.00000 Kilometer = 1000000.00000 Millimeters.\nThe circumference of the earth is 40,000 km Hence: The answer is 40000000 mm

The diametre of earth at the equator is about 12756 km (7926 mi). And at the poles it is 12713 km (7899 mi).\nThat is 43 km (27 mi) less than the equatorial diameter.

the average orbital velocity of earth is 29.783 km/s.\n\nhttp://en.wikipedia.org/wiki/Earth

The sun is by far the largest object in our solar system. It contains 98% of the solar system's total mass.\n\nIt would take 109 earths to stretch across the sun, and it would take over one million earths to "fill up" the sun if it were hollow.\n\nIf you think of the sun as being the size of a basketball, then the earth would be about the size of the head of a pin.\n\nThe diameter of the Sun is 865,400 mi \nEarth equatorial diameter=7926 mi (12760 km)\nEarth polar diameter=7900 mi (12720 km)\n\nSun's surface area is approximately 12,000 times that of Earth.\n\nMore info:

The circumference of the earth at the equator is approximately 24,902 miles.  This works out to about 40.16 times around.

Dan's result seems extremely low and the reason is that when he converted metres to inches he divided instead of multiplying so his final answer needs to be multiplied by about 1600.\n\nI don't think the earth's rotational speed around its own axis is relevant. I am unclear which Dan has taken, this or the earth's orbital speed around the sun.\n\nIf the radius of the Earth's orbit is 93 million miles, then the circumference of the orbit (assuming a circle for simplicity) is 2 pi r or 6.28 x 93 x 10^6 miles. In a fortnight (14 days out of 365) the earth will travel 14/ 365 ths of that distance (ignoring leap years for simplicity) and with 8 furlongs to a mile, that is\n\n8 x 14/365 x 6,28 x 93 x 10^6 f per f\n\nFor an approximate result, say 93 divides into 365 4 times, and divide the 4 into the 8 to leave\n\n28 x 6,28 x 10^6 furlongs per fortnight\n\n= approx 1.75 x 10^8 furlongs/fortnight\n\nOf course the sun itself is moving at about ten miles a second in the direction of Alpha Herculis, but that too is irrelevant to the calculation as is the rotational velocity of the earth on its own axis.

Circumference is 25,000 miles.  the diameter is about 7,950 miles, just under 8,000 miles (the earth isn't quite a sphere, it is a little pudgy at the equator, so the diameter varies slightly for our "oblique spheroid" which isn't a perfect sphere).

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

yes it goes around the sun.\n\nBut the sun orbit in the universe means that we orbit alot more suns although it would take billions billion years to do so.

About 92.9 million miles on average. This is also 147 million kilometers. The actual amount varies over time because the earth's orbit isn't a perfect circle. In astronomical terms, this is *very* close. If you made a scale model with the distance from the earth to the sun as 1 inch, then the distance to the nearest star (other than the sun) would be 4.3 *miles*.

The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).

The diameter of the earth at the equator is 7,926.41 miles

Earth has an average distance of 149,630,000 kilometers from the Sun,or around 93 million miles.\n\nThe term average is used since Earth's orbit is elliptical.  So it is closer at some particular months than in others.  It is closest in January and farthest in early July, 91,400,000miles (147,094,041km) and 94,400,000 miles (151,922,074km) respectively.\n\nThe moon is 384401 km or 238855 miles.  Again this is average due to the moon's elliptical orbit.  More info: apogee (farthest distance from the Earth) is\n406700 km, and perigee (distance of closest approach to the Earth)\nis 356400 km.

The rate at which solar radiation reaches a unit of area in space in the region of the Earth's orbit is: 1,366 W/m².\n\nDistance from the Sun:\n- Earth's orbit: RE = 1 AU (Astronomic Unit) = 1.496*10^11 m\n- Jupiter's Orbit: RJ = 5.20 AU = 7.7792*10^11 m\n\nIf energy is proportional to 1/r²:\nrate of solar radiation at Earth: SE = k/(RE)² = 1,366 W/m²\nrate of solar radiation at Jupiter: SJ = k/(RJ)² = ????\n\ncombining equations:\nSJ = (1.496*10^11 m)²(1,366 W/m²)/(7.7792*10^11 m)²\nSJ = 50.51 W/m²
