Just for fun

I've been playing with this "solar system" for far too long instead of Physics homework - so I thought I'd share

Cool! I like the "Four Star Ballet".

I agree: great fun to 'play god' with a new solar system. Now in our universe...

It will be a while before we know much about the details of other solar systems. Prof Chris Tinney is an exoplanet hunter in our school and I use some of his data as an example in

However, for a multi- stellar ballet, one can have a look at the orbits of some stars about the black hole at the centre of our galaxy, which I've used as an example in the Physclips chapter on Gravity (section 11.5)

This is pretty cool, my daughter is turning 7 and she is asking all these questions about planets, the sun and the stars. Some of the links here will come pretty handy! I've already started building a few 3-d models of the solar galaxy with her.

Sounds as though you might be raising an astronomer!
