How the early solar system may have formed.
|
|
|
How planets formed at varying distances from the sun.
|
|
|
Why planets are not continuing to run into debris during orbit.
|
|
|
Why the planets orbit in the same direction and roughly on the same plane.
|
Detailed explanation-1: -Because the cloud had an initial rotation, this same direction of spin has persisted; for the most part, the planets have retained their positions along the same orbital plane, according to astronomers.
Detailed explanation-2: -Why do the planets all orbit the Sun in (nearly) the same plane? This “co-planar” orbital motion is due to the fact that during the formation of the Solar System from a cloud of collapsing gas and dust the Sun and planets settled into a disk structure.
Detailed explanation-3: -The problem is that of getting the cloud to form the planets. The terrestrial planets can form in a reasonable time, but the gaseous planets take far too long to form. The theory does not explain satellites or Bode’s law and is therefore considered the weakest of those described here.
Detailed explanation-4: -The solar nebular theory supposes that planets form in the rotating disks of gas and dust around young stars. A rotating cloud of gas contracts and flattens to become a thin disk of gas around the forming sun at the center. Planets grow from gas and dust in the disk and are left in orbit when the disk clears.
