Explanation

The Interstellar Dust Hypothesis was proposed by the Soviet scientist Otto Schmidt in 1943. According to Schmidt, the earth and other planets were formed from gas and dust particles. He suggested that the sun captured a massive cloud of interstellar dust and gas, which then began to revolve around it. Through the process of collision and accretion, these particles condensed to form the planets.
