SUMMARY

Planets and stars do not move in the same orbital plane; they exhibit varying inclinations in their orbits. For instance, Pluto's orbital tilt is 17 degrees from the ecliptic plane, while other planets also have slight tilts. Stars orbiting supermassive black holes demonstrate diverse directional movements, contradicting the notion of uniform orbital planes. The formation of circumstellar disks, driven by the conservation of angular momentum during gravitational collapse, explains these orbital patterns.

PREREQUISITES
  • Understanding of orbital mechanics
  • Familiarity with gravitational dynamics
  • Knowledge of angular momentum principles
  • Basic concepts of circumstellar disks
NEXT STEPS
  • Research the effects of angular momentum on planetary formation
  • Study the dynamics of circumstellar disks in astrophysics
  • Explore the orbital mechanics of exoplanets
  • Investigate the behavior of stars in the vicinity of black holes
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in understanding the complex movements of celestial bodies in relation to gravitational forces.

why do planets move around stars in the same level ?
why do stars move around black holes in the same level?
why don't some of them move in horozintal level & the others in vertical level?

The short version is that they don't move around in the same level.

Stars and planets both have varying inclinations in their orbits and can even orbit "up and down". (Although there really isn't an up and down in space unless we define two directions to be so)

For example, the orbital tilt of Pluto is 17 degrees off from the "normal" plane that the rest of the planets are in. But even the other planets have slight tilts as well.

As for black holes, we have observed stars orbiting the supermassive black hole at the center of our galaxy in all sorts of directions.

Conservation of angular momentum of material that collapsed under gravitational attraction results in Circumstellar disk.
