Solar System

Verrou · 8 Feb 2009, 08:18

Is it possible, to make a solar system like model, using magnets where spheres revolve around others? I can't get mine to say "out" they always crash into the "sun" is there a way to make an object magnetic, yet a bit anti grav? So that it is repelled from the "sun" but still held near it due to it being magnetic?

Thanks

May be constrained to move along an elliptic or round trajectory. But I'm not sure the movement will not stop after a while at the nearest point between trajectory and Sun. How can you compensate the lost of kinetic energy ?
An other way : use motor-links with different speeds. For satellites you build sub-groups attached to planets.

Interested to see your simulation

Will give the motor links idea a try and will post results Thanks!

So far I have managed to do the inner solar system, however once I get to jupiter, it goes alot faster than any other of the planets :S Obviously it isn't to scale and I haven't added axial tilt etc. yet. But we'll see

Cool.

Thanks Any idea why Jupiter would go alot faster? Even though it is set the same speed, and has further to travel?

Hi Verrou

I watched your Solar system simulation yesterday evening ( living in France Tuesday 1Oth). May I suggest you change using UI (SketchyPhysic Tool bar) Max acc and Damp for each joint ( motors you've hidden in the Sun )?
The idea would be this : the remote the planet is, slower ( smaller values) you give to parameters.

Just see on an astronomical table, the planet's periods.  Mercury : 88 days  Venus : 250 days  Earth : 365 d., Mars : 667 d. then Jupiter ~ 11.4 years
and so on   ...Pluto  ~500 years.. .Then you may draw a diagram and so determine what values to attribute to each motor-planets...

Sorry for this frenglish...

Okay thanks Malaise Will work on it when I've finished my homework -.- Hate the stuff.
