Kepler's Laws of Planetary Motion 

This is beautiful

Fair enough! I wasn't comfortable with animations at the time I created this video, but will certainly give them a go in future astronomy videos. :)

Thank you for your lovely feedback! :D

Co?

Me

no he wasn't

kiran sundar lmao no

Hi! That is awesome to hear. I hope she gets great results. :D

I'm afraid not; the constant is simply a number that's roughly the same for every planet in a given solar system. It was useful historically because it allowed Kepler to understand how the planets moved, and later helped Newton to come up with his theory of gravitation. You can find out more about it here: en.wikipedia.org/wiki/Kepler%27s_laws_of_planetary_motion#Third_law_of_KeplerTo calculate the speed at which a planet travels, you need to divide the circumference of its orbit by the number of seconds in one year on that planet. (Circumference/time)Hope this helps! :)

I hope it helps! :)

It's the plural of 'focus'; the two points inside an ellipse that determine the shape of that ellipse. You can learn more on this website: www.mathopenref.com/ellipsefoci.html
