Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Solar system is believed to occur based on a certain theory. How does the planetesimal theory occur?
A
through a nebula that collapses further, local regions contract on their own due to gravity
B
through the collision of a star that created huge tides on the surface of our sun that resulted to erupted matter
C
through the pulled off material subsequently condensed to form the planets
D
through the planets that were formed from the substance that was torn out of the sun
Explanation: 

Detailed explanation-1: -In 1905 Chamberlin and Moulton announced the planetesimal hypothesis in which our solar system is considered to have originated from a spiral nebula.

Detailed explanation-2: -The planetesimal theory is a theory on how planets form. According to the planetesimal hypothesis, when a planetary system is forming, there is a protoplanetary disk with materials from the nebulae from which the system came. This material is gradually pulled together by gravity to form small chunks.

Detailed explanation-3: -The Protoplanet theory A dense interstellar cloud produces a cluster of stars. Dense regions in the cloud form and coalesce; as the small blobs have random spins the resulting stars will have low rotation rates. The planets are smaller blobs captured by the star.
