The protoplanetary nebular model is a theory that describes how planetary systems form from a disk of gas and dust surrounding a young star. According to this model, the planets form as material within the disk accretes onto planetesimals, which eventually grow into planets through collisions and gravitational interactions. This model is widely accepted in planetary science for explaining the formation of our own solar system and others.

What is the similarity of nebular hypothesis and protoplanet hypothesis?
Both the nebular hypothesis and the protoplanet hypothesis describe the formation of the solar system from a rotating cloud of gas and dust. The nebular hypothesis suggests that this cloud, or nebula, collapsed under its own gravity to form the Sun and planets, while the protoplanet hypothesis specifically focuses on how solid materials within the nebula coalesced to form planetesimals and eventually protoplanets. Both theories emphasize the role of gravitational forces and accretion processes in the development of celestial bodies. Ultimately, they aim to explain the origin and structure of the solar system.
The nebular model explains?
The nebular model explains how our solar system formed from a rotating cloud of gas and dust called a solar nebula. Gravity caused the nebula to collapse, forming a central protostar surrounded by a spinning disk. Over time, the material in the disk clumped together to form planets and other solar system bodies.
What model describes how the solar system formed?
The most widely accepted model for the formation of the solar system is the nebular hypothesis. This theory suggests that the solar system formed from a rotating mass of gas and dust known as the solar nebula, which collapsed under its own gravity to form the Sun and surrounding planets approximately 4.6 billion years ago.
What does nebular hypothesis explain?
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 that the Solar System formed from nebulous material.
What is a nebular cluster?
a cluster of stars.

Why photoplanet hyphothesis for the formation of the solar system?
I think you mean "protoplanet hypothesis". In fact, astronomers usually call it the Nebular Hypothesis A protoplanet is a planet-like object that hasn't fully developed into a planet. Why that hypothesis? It's because it is the best we have to describe the origin of the solar system according to the Laws of Physics.
How does the protoplanet nebular model account for the differences in terrestrial and giant planets?
The protoplanet nebular model explains the differences between terrestrial and giant planets primarily through their formation regions within the solar nebula. Terrestrial planets formed closer to the Sun, where higher temperatures allowed only metals and silicates to condense, resulting in smaller, rocky bodies. In contrast, giant planets formed farther out, where cooler temperatures enabled the accumulation of ices and gases, leading to the formation of large, gaseous envelopes around solid cores. This gradient in temperature and composition during the solar system's formation accounts for the distinct characteristics of the two types of planets.
When was the Nebular Hypothesis formed?
It was first proposed in 1734 by Emanuel Swedenborg. Originally applied only to our own Solar System, this method of planetary system formation is now thought to be at work throughout the universe. The widely accepted modern variant of the nebular hypothesis is Solar Nebular Disk Model (SNDM) or simply Solar Nebular Model.
The nebular model explains?
The nebular model explains how our solar system formed from a rotating cloud of gas and dust called a solar nebula. Gravity caused the nebula to collapse, forming a central protostar surrounded by a spinning disk. Over time, the material in the disk clumped together to form planets and other solar system bodies.
What is the definition of nebular model?
It is -------------------------- if your so smart why don't yopu look it up and not by the enternet :)
What theory says that objects in space developed from cooling condensing and contracting nebular gases.?
nebular
What is the definition of nebulahypothosys?
The nebular hypothesis is the most widely accepted model explaining the formation and evolution of the Solar System.
What does The nebular model explain.?
The creation of stars and planets into solar systems by condensation, concretion, and gravitational collapse.
Nebular Theory was proposed by?
There is evidence that the Nebular hypothesis was first proposed in 1734 by Emanuel Swedenborg.Immanuel Kant, who was familiar with Swedenborg's work, developed the theory further in 1755. A similar model was proposed in 1796 by Pierre-Simon Laplace.
What are the three theories on the origin of the earth?
The three main theories on the origin of the Earth are the nebular hypothesis, the giant impact hypothesis, and the core accretion theory. The nebular hypothesis proposes that the solar system formed from a rotating cloud of dust and gas, while the giant impact hypothesis suggests that Earth formed from a collision between a Mars-sized protoplanet and the early Earth. The core accretion theory posits that planets formed from the gradual accumulation of solid particles in a protoplanetary disk.
Was the earth formed of a nebular cloud?
a nebular creates stars as it caves in by its own gravity!
