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 created the solar nebula?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. After the Sun ignited, a strong solar wind cleared the system of gas and dust.
What is the theory of solar nebula?
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. The Nebular Theory would have started with a cloud of gas and dust, most likely left over from a previous supernova.
How was the solar nebula theory formed?
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.
What is the solar nebula quizlet?
Answer: Solar nebula is a massive cloud of gas and dust that collapses into itself, compresses the gas, heats up, and eventually (assuming its massive enough) begins nuclear fusion creating a star. The dust clumps together to form planetary bodies and whatnot.
What are the 9 planets in order?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
How is the solar nebula theory a scientific theory?
The solar nebula hypothesis states that the outer planets were able to collect hydrogen within their gravity, while closer to the sun, most of the hydrogen was blown away by solar winds, leaving less hydrogen and exposing the rocky core.
What does the solar nebula theory not explain?
Laplace theorized that the Sun originally had an extended hot atmosphere throughout the Solar System, and that this “protostar cloud” cooled and contracted. The main issue was angular momentum distribution between the Sun and planets, which the nebular model could not explain.
Why is the solar nebula theory considered a theory rather than a hypothesis?
Why is the solar nebula theory considered a theory rather than a hypothesis? It has extensive evidence and explains many observations of different objects.
How are planets created?
Planets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star. The planets nearest to the star tend to be rockier because the star’s wind blows away their gases and because they are made of heavier materials attracted by the star’s gravity.
How does the solar nebula theory help you understand the location of asteroids?
How does the solar nebula theory help you understand the location of asteroids? Many of the asteroids are material that would have formed a Terrestrial planet, but could not, due to gravitational pull from Jupiter and asteroids in places other than the belt are debris left over from the formation of the solar system.
What was the theory hypothesis about the origin of the solar system proposed by scientists Immanuel Kant and Pierre Simon Laplace?
The Kant-Laplace nebular hypothesis Kant’s central idea was that the solar system began as a cloud of dispersed particles. He assumed that the mutual gravitational attractions of the particles caused them to start moving and colliding, at which point chemical forces kept them bonded together.
