Wondering about wild grapes

Thursday, March 12, 2015

We all know that the planets, asteroids, and comets all orbit the star we call the sun.  Have any of you ever wondered just how fast we are traveling when we do that?  I found the following information on http://www.grandpapencil.net/projects/plansped.htm and it shows just what I was wondering about:



All of the planets spin (rotate) on an axis and at the same time orbit around the Sun.
This segment looks at just how fast each of the planets move.
I wonder why we don't all just fly off into space.

It is amazing that if we were standing on the equator we would be spinning around with the earth at 1040 mph and not only that we would be spinning around the sun at 66641 mph!!  And you wonder why I am Dizzy. . .

Now you will understand why the stuff we sweep up on this orbital trip moves so fast that when it enters our atmosphere it heats up and the smaller ones burn up completely before smashing into the earth.  OK, I just thought that some of you would find this chart interesting.  Either way, if you did or didn't, I want you to have a great day, you hear?

  1. I'm wondering what makes Jupiter and Saturn spin so fast.

  2. They are not spinning as fast as it appears. They have a huge diameter compared to the other planet so even if thy were spinning at the same rate (rpms) a point at their equators would be speeding at a high miles per hour because of the large diameter.

  3. It makes sense when you put it that way, but it's a little too complex for my mind to comprehend on a spring day!

  4. I'll admit I've never thought of this before.... today my main thought was... What time will we arrive in Livingston? (4pm)

  5. You are making me dizzy, to read how fast we are spinning. No wonder I get vertigo now and then.
