Origins of the Solar System

Question 1

What states that the sun encountered a rogue star. Upon encounter, gas was removed from both stars due to gravitational interaction of the two stars. The hot gas then accumulated and formed the planets where the rogue star, being less dense, formed the outer planets and the sun formed the inner planets?

Answer 1

Encounter Hypothesis

Question 2

It suggest that a cloud of gas and dust that is about 10 million kilometers in diameter rotated slowly. Then either because if it’s own gravity or by the explosion of a passing star, the cloud of gas and dust began to collapse. As it cooled by radiation and contracted, it rotated faster and faster causing the gas to take a disk-like form that later became the planets.

Answer 2

Protoplanet Hypothesis

Question 3

What is the most favored model for the origin of the solar system?

Answer 3

Nebular Hypothesis

Question 4

Who was the one that first proposed about the Nebular Hypothesis?

Answer 4

Immanuel Kant Pierce Simon Laplace

Question 5

It suggest that the solar system was formed from a slowly rotating cloud of gas or a solar nebula that collapsed and flatten with a hot central region known as the sun and the remaining became the planets and everything else.

Answer 5

Nebular Hypothesis
