Why is the Nebular Theory the most accepted theory?
The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun.
What is the evidence that supports the nebular hypothesis?
The types of objects found within the solar system provide significant clues and evidence to support the Nebular Theory. Comets, asteroids, and meteorites recovered on Earth also provide a number of clues and evidence of Nebular-type development.
How does Nebular Theory differ from the encounter theory?
One of the earliest theories for the formation of the planets was called the encounter hypothesis. In this scenario, a rogue star passes close to the Sun about 5 billion years ago. Material, in the form of hot gas, is tidally stripped from the Sun and the rogue star. A second theory is called the nebular hypothesis.
What does the Nebular Theory 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].
Which theory best describes today’s current thinking about the birth of a solar system?
Currently the best theory is the Nebular Theory . This states that the solar system developed out of an interstellar cloud of dust and gas, called a nebula . This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects.
What is the most widely accepted hypothesis of Earth origins?
the nebula hypothesis
The most widely accepted hypothesis of Earth’s origins is the nebula hypothesis.
What evidence do we use to support our theories of how the solar system formed?
Summary: Scientists are using new computer models and evidence from meteorites to show that a low-mass supernova triggered the formation of our solar system.

What are the different theories behind the origin of the Solar System?
These are the Nebular Hypothesis of Laplace, the Planetesimal Hypothesis of Chamberlin and Moulton, and the Capture Theory of See. Darwings theory of Tidal Friction is scarcely a distinct hypothesis, but is mentioned separately on account of its application to all of the others.
What are the different theories about the origin of the solar system?
Why was the nebular theory rejected?
As the nebula became smaller, it rotated more rapidly, becoming somewhat flattened at the poles. In the early 20th century, the nebular hypothesis was rejected and the planetesimal hypothesis, that the planets were formed from material drawn out of the sun, became popular. This theory, too, proved unsatisfactory.
