What is the difference between nebular hypothesis and Protoplanet hypothesis?
The Encounter Theory suggests that the Solar System formed as a result of a near collision between a passing star and the Sun. The Protoplanet Theory is a modified version of the nebular hypothesis stating that the Solar System started from a nebula that was disrupted which led to the formation of protoplanets.
What does the nebular hypothesis not explain?
The main problem involved angular momentum distribution between the Sun and planets. The planets have 99% of the angular momentum, and this fact could not be explained by the nebular model. As a result, astronomers largely abandoned this theory of planet formation at the beginning of the 20th century.
How was the solar system being formed in nebular hypothesis?
The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud—the solar nebula. – (Nebula is the Latin word for cloud.) Kant and Laplace proposed the nebular hypothesis over two centuries ago.
What is solar nebula explain the formation of nebular disk?
solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart.
What does the nebular hypothesis explain?
The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].
Why was the nebular hypothesis rejected?
The main issue was angular momentum distribution between the Sun and planets, which the nebular model could not explain.

Why is the nebular theory important?
The nebular hypothesis is the possible explanation for how the Sun, the Earth, and the rest of the solar system formed approximately 4.6 billion years ago out of the gravitational collapse of a large cloud of gas and dust left behind from previous star formation and star life cycles.
What supports the solar nebula theory?
We see stars forming in the depths of giant clouds of gas and dust, and we even see young stars with disks of debris around them, which look just like the debris disk we think the planets formed from. Other lines of evidence come from simulations of the process.
Who gave the theory of nebular hypothesis?
The first version of the nebular hypothesis was proposed in 1755 by the German philosopher Immanuel Kant and modified in 1796 by Pierre Laplace. The nebula that according to this hypothesis condensed to form the solar system is called the solar nebula.
What is solar nebula answer?
Complete answer: The solar nebula theory states that the Sun, Planets, and the Solar System were created from a massive cloud of gas and dust. The molecular cloud dissolved under its own gravity, forming a star known as the Sun in the middle.
What are the weakness of nebula cloud theory?
Weakness- The main weakness of the theory involved the distribution of angular momentum between the sun and the planets. 99% of the angular momentum belongs to the planet, this fact could not be explained by the nebular theory.

Definition. A nebula is a cloud in deep space consisting of gas or dirt/dust (e.g. cloud formed after a star explodes). Solar Nebula is the cloud of gas and dust that began to collapse about 5 billion years ago to form the solar system. Proposed.
Why are galaxies called nebulas?
In the earlier time, galaxies were also called nebula by astronomers because of their fuzzy appearance. However, nowadays the word nebula is used for extended objects consisting mostly of gas and dust. It comes in many shapes and sizes and forms in many different ways.
What is the name of the gaseous cloud that formed the Sun and the planets?
Solar nebula is the gaseous cloud which originated the solar system, and the Sun and the planets were formed by contraction. The giant molecular cloud is known as the solar nebula. There was one event like a supernova explosion that caused the solar nebula to collapse, creating regions of higher density.

The Nebular Hypothesis
The nebular hypothesis is the possible explanation for how the Sun, the Earth, and the rest of the solar system formed approximately 4.6 billion years ago out of the gravitational collapse of a large cloud of gas and dust left behind from previous star formation and star life cycles. A nebula is an interstellar cloud of gas and dust.
What is a Solar Nebula?
The nebular hypothesis states that the Sun began to form approximately 4.6 billion years ago, and the rest of the solar system began to form around it ~4.5 billion years ago. Once a star begins to form a nebula is considered a solar nebula. Solar nebula is also used to refer specifically to the cloud of gas and dust that formed the Sun.

Below is a historical timeline of the development of the nebular hypothesis:
Why do stars form in nebulas?
The word “nebula” is Latin for cloud, and this theory proposes that stars form inside of massive, dense clouds of molecular hydrogen. These clouds begin to rotate due to unstable gravity, and matter within them begins to gather together into smaller, distinct bodies.
Which hypothesis explains the origins of our solar system?
The Nebular Hypothesis [ 1] is currently the most widely accepted hypothesis that explains the origins of our solar system, and possibly other planetary systems too. According to the Nebular Hypothesis, our solar system formed from material in a large nebula.
What is condensation theory?
If I understand it right, the condensation theory is nebular theory with one difference- it suggests that the Moon and the Earth emerged from accretion of nebula in different part of solar system and the Moon was captured later. But this can’t explain why the element composition of the Moon is the same as that of Earth, which suggests that Moon and Earth has the same beginning in one body.
What is the name of the theory that incorporates interstellar dust as a key ingredient?
Condensation Theory: An extension of Nebular Theory that incorporates interstellar dust as a key ingredient. The solar nebula is initially a thin gas of hydrogen and helium strewn with tiny dust particles. ... These grains act as condensation nuclei, on which accretion of matter occurs.
How many light years does it take for a solar system to start?
I'm not the expert on this, but I vaguely recall reading somewhere that solar systems typically start with clouds of random matter roughly 20 parsecs (65 light years) across. They mostly molecular hydrogen. The higher the temperature the more pressure it takes to keep the molecules together, but the usual temperature is about 12 k, so the pressure is minimal. It comes from the cloud's own gravity.
What caused the ejection of the mass from which the Moon emerged?
That means ProtoEarth was rammed by Theia (planetezimal as big as Mars is) which caused ejection of large amount of the mass from which the Moon emerged by accretion. Further more, the collision must have bee
Why do stars form?
Because stars form under very similar conditions. The vast clouds of stellar debris we call Nebulae provide the material for new stars, and it’s the nature of a forming star to attract a lot of material as it’s gravity increases. Some of this material goes into orbit around the forming star… An “accretion disc”. These discs hold enough material for planets to form and not be drawn into the new star itself.
