Explanation: 

Detailed explanation-1: -The Chamberlin–Moulton planetesimal hypothesis was proposed in 1905 by geologist Thomas Chrowder Chamberlin and astronomer Forest Ray Moulton to describe the formation of the Solar System.

Detailed explanation-2: -Moulton and Thomas C. Chamberlin about 1900. The theory states that the planets were formed by the accumulation of extremely small bits of matterplanetesimalsthat revolved around the sun. This matter was produced when a passing star almost collided with the sun.

Detailed explanation-3: -Chamberlin. According to this theory, a star narrowly missed colliding with the Sun and, in its passing, drew away from the Sun stellar debris that condensed to form the planets. Jeans applied mathematics to problems in thermodynamics and radiant heat and wrote on other aspects of radiation.
