|
|
|
The planets’ positions in the solar system happened by chance.
|
|
|
The planets formed in the same plane as the flattened nebular disk
|
|
|
Large celestial objects can only fit on the same orbital plane as the sun.
|
|
|
The gravitational forces between the planets cause them to share an orbital plane.

Detailed explanation-1: -It’s thought to have arisen from an amorphous cloud of gas and dust in space. The original cloud was spinning, and this spin caused it to flatten out into a disk shape. The sun and planets are believed to have formed out of this disk, which is why, today, the planets still orbit in a single plane around our sun.
Detailed explanation-2: -As gravity condensed the gas, rotation of the gas increased, spreading the gas cloud into a rotating disk that would form the plane of the solar system as we know it today. Evidence of this can be seen because all of the planets revolve around the sun in the same plane and direction.
Detailed explanation-3: -In essence, this theory states that the Sun, the planets, and all other objects in the Solar System formed from nebulous material billions of years ago. Originally proposed to explain the origin of the Solar System, this theory has gone on to become a widely accepted view of how all star systems came to be.
Detailed explanation-4: -The most widely accepted model of planetary formation is known as the nebular hypothesis. This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.
