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 ...
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...

Around a million quasars have been catalogued in the Universe by probing deeper and using new methods for discovery. However, the hardest ones to find seem to be the rarest and brightest specimens. Here we study the properties of the most luminous of all

Learn about accretion theory. Study the accretion definition, discover the many processes of planetary accretion, examine current models like the core accretion theory, and identify ongoing issues with accretion theory. Related to this Question
Formation of the Planets What is wrong with the accretion theory? Most scientists agree that core accretion is how terrestrial planets such as Earth and Mars were created, but the model can't convincingly explain how gas giant planets like Jupiter and Saturn came to be. One major problem is ...
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...
