What is the condensation theory of solar system formation?
The condensation theory of the solar system explains why the planets are arranged in a circular, flat orbit around the sun, why they all orbit in the same direction around the sun, and why some planets are made up primarily of rock with relatively thin atmospheres.
What does the condensation theory explain?
What is condensation sequence?
In planetary science, the condensation sequence refers to the order in which chemical compounds transition from gas to solid phase in a protoplanetary nebula (disk), based on the condensation temperature of each compound.
When was the condensation theory proposed?
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 are the four materials of nebular theory?
Composition. The ingredients of the solar nebula fell into 4 categories based on their condensation temperatures: metals, rocks, hydrogen compounds (water, methane, ammonia), and light gasses (hydrogen and helium). Distance of a planet from the Sun determined the temperature and thus the materials which condensed first …
Who is the proponent of condensation theory?
This theory was presented by Robert Jastrow.
What is the difference between the nebular theory and the condensation theory?
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.
Who proposed condensation theory?
This theory also proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the moon formed in orbit around the Earth. This theory was presented by Robert Jastrow.
What makes planetesimal so important in a planet formation?
The ultimate outcome of the planetesimal formation stage is the production of planetesimals of sufficient sizes to obtain gravitational cross sections much larger than their physical cross sections, hence accelerating the growth toward fully fledged planets.
What does the word planetesimals mean?
: any of numerous small celestial bodies that may have existed at an early stage of the development of the solar system.
