Detailed explanation-3: -In 1949 Kuiper proposed an influential theory of the origin of the solar system, suggesting that the planets had formed by the condensation of a large cloud of gas around the Sun. He also suggested the possible existence of a disk-shaped belt of comets orbiting the Sun at a distance of 30 to 50 astronomical units.

Detailed explanation-4: -This hypothesis was proposed in the 1900’s by astronomer Carl von Weizsäcker and geologist Gerard Kuiper. Together, they created a hypothesis that begins with a cloud comprised of gas and dust. About five billion years ago, this ten billion kilometers in diameter cloud gradually rotated in space.
