But the Sun is tiny compared to the solar system which is tiny compared to the distance to the next star. Oh, did we mention that there are over 100 billion stars in our galaxy (which is about 100,000 light years in diameter) which is one of hundreds of billions of galaxies in just the observable universe (which might be infinite for all we know). Don't feel small. We find it liberating. Your everyday human stresses are nothing compared to this enormity that we are a part of. Enjoy the fact that we get to be part of this vastness! About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

Wow that was so interesting

The earth is a sphere if it was flat it the moon would be flat then the earth would be flat, and you would already now what shape it would be with comparing the shape of the other planets
-
You repeated 17 years... 5 times.
-
Why do you repeat so many times!
-
hi
-
80 hours to go around the earth
-
What is a constant?
Is the speed of light a constant?
Is the speed of which earth is traveling around the sun a constant?
Is the speed of which earth's self rotation a constant?
Is the distance between two digits ^ ^ constant?
What is time? -
Thanx this video helped!
-
What's he using to write? It can't be a mouse at that speed and neatness can it?
-
You haven't put another fucking video in Astronomy or History for what, over 3 fucking years?!!! I guess that was everything!! It's all been covered, nothing else happened!!
