Question
Describe Nebular hypothesis origin of planets.
Solution
Nebular hypothesis:
(i)The hypothesis considered that the planets were formed out of a cloud of material associated with a youthful sun, which was slowly rotating.
(ii)Later in 1900, Chamberlain and Moulton considered that a wandering star approached the sun. As a result, a cigar-shaped extension of material was separated from the solar surface.
(iii)As the passing star moved away, the material separated from the solar surface continued to revolve around the sun and it slowly condensed into planets.
