Early planetary formation thought

Click For Summary
SUMMARY

This discussion centers on the theories of early planetary formation, specifically the idea that planets may have begun forming before the Sun (Sol) itself. Participants explore the potential influence of the Sun's gravitational pull, solar wind, and radiation on the creation of Lagrange points within the solar nebula, which could have impacted planetary formation. The conversation also considers the possibility that the Sun's emissions were too distant to affect the formation process, leading to the dispersal of matter into the Oort cloud.

PREREQUISITES
  • Understanding of planetary formation theories
  • Familiarity with solar physics, including solar wind and radiation
  • Knowledge of Lagrange points and their significance in celestial mechanics
  • Awareness of the Oort cloud and its role in the solar system
NEXT STEPS
  • Research the role of solar wind in planetary formation
  • Study the concept of Lagrange points in detail
  • Examine the characteristics of the Oort cloud and its formation
  • Investigate historical theories of planetary formation and their evolution
USEFUL FOR

Astronomers, astrophysicists, and students of planetary science interested in the dynamics of early solar system formation and the interactions between solar phenomena and planetary bodies.

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.

Greetings! Interesting theory! I hadn't heard of this before. It does seem like the gravitational pull of the Sun and the pressure of the solar wind and radiation could possibly create Lagrange points. However, it could also be that the powerful emissions of the early Sun were too far away to affect planetary formation and blew away the free matter into our Oort cloud. It's definitely an interesting question and I'm looking forward to hearing other opinions on this.
