I read somewhere else that the correct answer is in the range of .5% the speed of light but to get a sense of what's going on, check out this brief vid:

The earth travels around the sun in an elliptical orbit. I'm pretty sure that its average distance from the center of the solar system is about 93 million miles? If that is true, the earth would travel about 584 miles on its journey around the sun. That is about 1.6 million miles per day, or 67 thousand miles per hour. This is a very rough estimate, but it's pretty fast anyway!

Well we know that the earth take about 25 hours to go ones around the sun. So the father away the planet is the longer it takes for the planet to move once around the sun.

The Earth moves around the sun at 18.55 mph or 66780 mph.

I'm sure AarthiAru meant 18.55 mps or 66,780 mph. This can be calculated given the fact that the Earth is about 93,000,000 miles from the sun, and that its orbit around the sun is approximately circular. The circumference of a circle is 2 pi times the radius, so the Earth travels about 6.28 x 93,000,000 = 584,000,000 miles (to the nearest million) in one year, which is about 60 x 60 x 24 x 365.25 = 31,557,600 seconds. Dividing 584,000,000 by 31,557,600 I get 18.5058 mps (to 4 decimal places), but I was using approximate numbers to begin with. So we're in the same ballpark.

But more to the point, strictly speaking the question is meaningless. How fast does the Earth move through space? It depends on your frame of reference. That was the conclusion of the Michaelson-Morley experiment about 100 years ago, which attempted to measure exactly that. Einstein gave the definitive answer by publishing his Special Theory of Relativity. Relative to the sun, 18.55 mps is the right answer. But the Earth also moves with the sun around the center of the Milky Way Galaxy at a much higher speed. And then there's the speed of the galaxies flying away from each other. So it's all relative.

When you can snatch the pebble from my hand, the answer will be given. But most importantly, if it all started from a big bang, which occured from an incredibly small speck of an atom, then we must ask the questions we have all along. Why? How? Where are we going? Who wrote the formula? Is there an impartial set of laws that govern it all? How come we continue to be so dumb? When will we begin to learn from our foolish ways? If we know all that we know why are people still killing? Surely we are being watched and led toward something that mirrors the amount of knowledge we have acquired?
