Greetings !

Some less popular theories, at this time,
suggest that planets formed or at least
began to form before the Sun had formed.
I'm not sure that I agree with that, but
it's worth remembering as another counter
example to the idea I just thought about.

Anyway, the idea I just thought about is:
Suppose that the planets formed after the
Sun(Sol) was formed. Now, is it possible
that the gravitational pull of the Sun on
the one hand and the pressure of the solar
wind and aspecialy solar radiation on the
other hand could've created certain La'grange
points for various types of ellements and
molecules in the early solar nebula that
could've somehow affected planetary formation ?
Or, were such points too far away for the powerful
emmissions of the early Sun which is also
why all the free matter got blown away into
our Oort cloud ?

All opinions are welcome. :smile:

Live long and prosper.
