Hipotesis nebula adalah gagasan bahwa awan debu berputar yang sebagian besar terdiri dari unsur-unsur ringan, yang disebut nebula, diratakan menjadi piringan protoplanet, dan menjadi tata surya yang terdiri dari bintang dengan planet-planet yang mengorbit [12]. WebbJust like the Nebular hypothesis, the Protoplanet hypothesis has some problems too. For example, the Protoplanet does not explain why the planets’ distances from the sun vary. Another issue with this hypothesis is that it does …show more content… The Protoplanet hypothesis and the Planetesimal hypothesis are different from this.

WebbList the steps of the nebular theory of Solar System formation. 1) planetesimals begin to form in a disk. 2) protoplanetary disk forms. 3) some planetesimals grow into protoplanets by incorporating other solid materials into their orbits. 4) differentiation occurs when a protoplanet has grown to a diameter to at least 400 km.

Webb22 juni 2024 · The nebular theory explains that the solar system originated from a nebula – a gas cloud made up of hydrogen particles. Before the nebula is stable, it is believed that a nearby supernova resulted in the disruption of a nebula. This disruption created areas of high density, and as these areas were formed, gravity acted, pulling other materials to it. grant officer technical representative

Knowing nothing about the true source of energy in stars, Laplace assumed that as the Sun radiated away from its heat, it would begin to cool. " - The protoplanet nebular model
