It varies between 147,090,000 km and 152,100,000 km, because the Earth's orbit is elliptical, not circular.

It would depend on where Earth and Jupiter are in their orbits.\n\nAt the closest point, when Earth and Jupiter are aligned, their distance may be "only" 628.7 E6 km.\nOr when Earth and Jupiter are on oposite sides of the sun, the distance may be as much as 927.9 E6 km.

"If the earth were a hundredth of an inch closer to the sun, we would burn to death and if it were one hundredth farther from the sun, we would freeze to death"\n\nHA HA HA HA HA HA LOL ROTFL\n\nThat's what you get for reading fairy tale books instead of science books... actually the earth is at 152 million km from the sun at aphelion and 148 million at perihelion (6 million km closer) ... get a clue!!

Roughly 584 million miles --\n\n2 * pi * 93 million miles\n\nThe earth's orbit is actually an ellipse with eccentricity = 0.02, but the above calculation is a pretty good approximation.

According to www.about.com the circumference of the earth measured at the equator is 24,901.55 miles. Measuring through the poles is a slightly shorter distance at 24,859.82 miles.

We have the ability now to measure the orbit of the Earth, and all other planets, to very high precision, and it is not getting closer to the Sun.\n\nYou can do a very rough measurement yourself. If the Earth gets closer to the Sun, the Sun will appear bigger in the sky. Measure it in photographs taken by the same telescope a year apart. \n\nAnother consideration is this. Currently, the Moon and Sun appear the same size in the sky, which produces spectacular total eclipses of the Sun. If the Earth got just a little closer to the Sun, the Moon would no longer be able to completely cover the Sun. So if total solar eclipses continue as usual, that is evidence the Earth is not getting any nearer to the Sun.

sun is already 5 billion years old the distance between sun and the center of galaxy is 10kpc and the sun rounding the center of galaxy in a circular orbit so we can find the value : and it is 24*10^7 years

the "smart kid" is incorrect about the size of the sun.  It is only 109 times larger than the planet earth.  The Sun's diameter is 864,938 miles (1,391,980 km). This is almost 10 times larger than the planet Jupiter and about 109 times as big as the Earth. The volume of the Sun is 1,299,400 times bigger than the volume of the Earth; about 1,300,000 Earths could fit inside the Sun.

The distance between the earth and the sun is not constant.  The earth's\norbit around the sun is nearly circular, but not perfectly so.  The earth\nis actually closest to the Sun in the northern hemisphere winter, but the average distance between the earth and the sun is 93,000,000 miles.

3,634,066,905 miles!\n\nMercury is an average 35,983,095 miles from the sun.\n\nPluto is an average 3,670,050,000 miles from the sun.\n\nThat's just an average though! Both of their distances from the sun vary a lot.

The earth is not a perfect sphere. It's slightly 'wider' than it is tall, so you could measure the circumference at the equator (24,901.55 miles or 40,075.16 kilometers). If you go through the south and north poles (24,859.82 miles or 40,008 km)

This is a great question, actually, and one that bothered astronomers for centuries.  In short, there’s no simple way to measure the distances to planets—at least not without really good telescopes (and a bit of luck).\n\nIn the early 17th Century, Kepler devised his Third Law, which releated the distance of a planet from the Sun and the time it took to revolve around the Sun.  So if you know one interplanetary distance, you can figure out the rest.  Which is all well and good, except that there were no good distances at the time.  (A rough sense of the distance between the Sun and Earth constrained the numbers somewhat, but the estimates were pretty far off—Kepler thought the Solar Syatem was about one seventh its actual size.)\n\nThe first accurate means of determining the distances was by observing transits of Venus across the face of the Sun.  Through relatively simple trigonometry, one can calculate the actual distances between the Sun, Venus, and Earth.  Unfortunately, transits don’t occur very frequently, so it was only in the 19th Century that reasonable results were achieved.\n\nNowadays, the distances to planets are determined by bouncing radar off them.  Because we know how fast light travels, we can simply measure the time between emitting a radio pulse and its return back to Earth, which gives us the distance!  Easy as pie…\n\n(In the case of the Moon, we actually bounce lasers off a reflector left there by Apollo astronauts.  Because of the phase information of the laser light, we can get extremely accurate distances to our nearest neighbor.  That’s how we confirmed that the Moon is moving away from us at the rate of about 3.8 centimters per year.)\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

Astronomers determined the size and shape of our galaxy and measured distances to other stars using the “parallax method” (and eventually other methods using the star’s light spectrum).  Unfortunately, these methods do little to help us find out the exact distance to our very own star, the Sun.  Surprisingly, to get the distance to the sun, astronomers first had to determine the exact distance to Venus!\n\nWith the invention of radar, scientists were able to measure the distance to Venus very precisely.  By timing how long it took the radar beam to travel at the speed of light to Venus and back, the total distance to the object can be determined from the equation:\n\nDistance = (Speed of Light) X (Total Time)/2\n\nThe reason the total time is divided by two is to get just the distance from the Earth to the object.\nEarth-Sun Distance = (Earth-Venus Distance) / (Cos q)\n\nUsing trigonometry, astronomers now know that the “Astronomical Unit” = 92,955,820.5 miles (149,597,892 kilometers).  This incredible degree of accuracy is possible because the speed of light is known very precisely and extremely accurate clocks are used to time the radar reflection.  Radar can’t be used to determine the distance to the Sun directly because the Sun doesn’t have a solid surface to reflect the radar efficiently.

About 8.\n\n\nTo clear up any  ambiguity contributed here by some--- The average distance from the Earth to the Sun (or 1 astronomical unit) is 8.317 light minutes. Saying it's "more" or "less" sometimes is stating the obvious-- it's an AVERAGE. Saying it's "usually" different than its average, is nonsensical. \n\nhttp://en.wikipedia.org/wiki/Light_minute

This is actually a difficult question to answer because the planets are moving in their orbits all the time, and so the distance from each planet to Earth is constantly changing. When both planets are on the same side of the Sun, and form a line with the Sun, then they are closest to each other. When two planets are on opposite sides of the Sun, and form a line with the Sun, then they are farthest away. For example, the planet Venus is about 42 million kilometers (26 million miles) from Earth at its closest point and about 258 million kilometers (160 million miles) away at its most distant point. \n\nUsually when people ask this question, what they mean is "What is the distance between the orbit of Earth and the orbit of each planet?" or "What is the closest that each planet comes to Earth?" (These are essentially the same question, right, because the planets can't get any closer than their orbital spacing allows.) You can compute this in a rough way by assuming that the orbits are circular, and looking at the planet-to-Sun distance for each planet. Since the distances are so large, we usually express them in Astronomical Units (AU). (An AU is the distance from Earth to the Sun, about 150 million kilometers or 93 million miles). The list below shows the distance of each planet from the Sun in AU. \n\nPlanet Distance from Sun in AU \nMercury 0.39 \nVenus 0.72 \nEarth 1.0 \nMars 1.5 \nJupiter 5.2 \nSaturn 9.5 \nUranus 19.2 \nNeptune 30.1 \nPluto 39.5 \n\nTo find the distance between the orbits of two planets in AU, subtract the two planet-Sun distances. For example, Earth orbits at 1 AU from the Sun and Venus orbits at 0.72 AU from the Sun. The difference between these two distances is 1 - 0.72 = 0.28 AU. To get the number in kilometers, multiply by the conversion above: 0.28 x 150 = 42 million kilometers. \n\nThe numbers above are generally what's used in introductory astronomy classes.

Of course the Moon is closer than the Sun.\n\nThe average distance from the earth to the sun, the semimajor axis of its orbit, is 149,597,890 km.\n\nMoon's orbit is elliptical: its average orbital radius is 384401 km, apogee (farthest distance from the Earth) is 406700 km, and perigee (distance of closest approach to the Earth) is 356400 km.
