EVERYDAY SCIENCE

Detailed explanation-1: -Today, we’ve mapped out the orbits of the planets to incredible precision, and what we find is that they go around the Sun-all of them-in the same two-dimensional plane, to within an accuracy of, at most, 7° difference.

Detailed explanation-2: -Although all the planets and asteroids follow elliptical orbits around the Sun (obeying Kepler’s First Law), these orbits do not all lie in the same plane – they are usually tilted with respect to each other.

Detailed explanation-3: -All the planets, asteroids, meteoroids, and comets in the solar system orbit the sun. This is called heliocentric orbit. Almost all these bodies also travel in the same orbital plane, a thin disk surrounding the sun and extending to the edge of the solar system.

Detailed explanation-4: -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.
