Theory of planet formation

Webb7 maj 2001 · Alan Boss, a planetary scientist at the Carnegie Institution of Washington and a member of the NASA Astrobiology Institute, has developed a different theory, based on computer models, about how planets like Jupiter may have formed. He believes gas giants could form as a result of instability in a star’s protoplanetary disk. Webb16 mars 2011 · There are two theories that are generally regarded for the formation of the outer planets. One is the core accretion theory, while the other is the disk instability. Theoretically, both can form the outer planets but with difficulties. For simplicity sake, we will examine only the core accretion theory. Planetesimals, in the form of icy dust ...

WebbThere are two widely held theories for how giant gas planets can form: core accretion and disk instability. Core accretion occurs from the collision and coagulation of solid particles into gradually larger bodies until a massive enough planetary embryo is formed (10-20 Earth masses) to accrete a gaseous envelope.

A major problem with the supernova theory of planet formation is that the neutron star that is the remnant of a supernova explosion is absent. There are no neutron stars near our Solar System. The closest neutron star is more than 250 light-years away from Earth.

WebbThe planets continued to grow over the course of many thousands or millions of years, as material from the protoplanetary disc was added. Both rocky and gaseous planets … Webb30 dec. 2024 · When astronomers found the first giant planets with orbits of only a few days, they did not know whether those planets were gaseous and liquid like Jupiter or rocky like Mercury. The observations of HD 209458 settled this question because observations of the transit of the star by this planet made it possible to determine the radius of the planet.

WebbAccording to one hypothesis, the planet`s gravitational field tugs on the protoplanetary disk of dust and gas from which it formed. The disk exerts its own gravitational tug, and this interplay of forces robs the planet of momentum in its orbital path, forcing it to spiral in toward the star.

WebbPlanetesimal Formation. Planetesimals are the building blocks of planets. Asteroids and comets are leftover planetesimals from the time of formation of our own solar system.
