Planetary SystemGiant PlanetProtoplanetary DiskA comparison of solar system properties to experimental data derived from observations of exoplanets results in a significant revision of the accretion theory. We describe some new ideas of the present-day theory of the origin of planets and planetary ...
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 cr
1 . If accretion takes place in eccentric orbits as well, the rotation will be prograde and of the right order of magnitude.如果吸积发生在偏心轨道,则自转将是正向的,且快慢也合适。 2 . The selective accretion theory chalks it up to high gas density in the early solar system, during the ...
9、In a one-star system like our solar system, the leading theory as to how the planets formed is through a process calledaccretion.(在单星系如我们的太阳系中,普遍认定行星是通过吸积的过程逐渐形成的。) 10、The implication is that the gases in the mantle came not from the sun but from th...
Earth’s origins are challenging to elucidate, given the lack of surviving terrestrial geology from the first 500 Myr of the Solar System. In this Review, we discuss breakthroughs in geochemistry and theoretical modelling that have advanced understanding of Earth accretion. Theory holds that solar...

Cold accretion theory is a term that can be used to distinguish modern theories of planet growth from earlier theories. The mechanics of modern cold accretion are reviewed in the article Accretion. Ear...William K. HartmannSpringer Netherlands...
But what about those gas planets in the outer solar system, in the outer accretion disk? Well, the first theory says the accretion process was similar to the one that formed the rocky planets, with some key differences. Remember, the gas giants are farther from the sun, where temperatures ...
So if all we believed about planet formation was based on our own solar system, and it turns out that our solar system lacks at least one fairly common type of planet. Then what does that say about what we really know? 2.What does the core accretion theory predict based on the ...
