Question

The orbit of the planets all seems to align in a plane. The planet's obits have been mapped with only at most a 7° difference to each other. What evidence explains this phenomenon?

Answer 1

Answer:

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.
