I always tell people that we're travelling at 80k miles an hour around the sun,
but if the earth is 94.5 million miles from the sun, then are we travelling at 34k miles an hour, aren't we?
Happy Labor Day Weekend to you all.
BTW-This is Labor Day, not Memorial Day, right? And Labor is spelled Labor and not Laber or Labre. haha
Circumference = Diameter x 3.14. (That sounds about right).
The Earths distance from the sun = 94,500,000 miles, but that could be debated.
Its circumference of travel = 94,500,000 * 3.14 = 296,730,000 miles. (Sort of, discounting any wobble).
Days to circle the sun = 365.4, or 8770 hours (you can prove this by calibrating a sticks shadow to a watch).
Miles per hour = 296,730,000 mile / 8770 hours = 33,834 miles per hour.
Add to that,
The Earth has a circumference of 24,901 miles (at the equator, maybe), (once again with sticks, 2 stick's shadows a mile apart can prove this out)
and there are 24 hours in a day (or something close to that),
Then we are spinning at 1,000 miles an hour (roughly).
