What is the current theory about the formation of the solar system Brainly? Answer: The most widely accepted theory of planetary formation, known asthe nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which...
ln the modern version of their theory, the solar nebula is thought to have had a mass somewhat greater than that of our present-day Sun. Each part of the nebula exerted a gravitational attraction on the other parts, and these mutual gravitational pulls tended to make the nebula contract.As...
Reports that scientists have found evidence that calcium-aluminum-rich inclusions (CAI) and chondrules may be of the same age. Support of a theory of solar system formation; Examination of a meteorite that contains a CAI and a chondrule embedded inside it....
The Formation of the Solar System Astronomers estimate that the solar system is somewhere around five billion years old and have several theories regarding its creation. The most common-and most widely accepted-one is the nebular hypothesis. According to this theory, the solar system developed from...
内容简介· ··· This book traces the development of ideas about the origin of the Solar System from ancient times to the present day. A survey of more modern ideas, covering the last 200 years or so, highlights the difficulties experienced by theories and also points the way towards the ...
A model describing a gravitational effect into a forming gravitating and rotating cosmological body based on the statistical theory has been proposed. In t... AM Krot - 《Chaos Solitons & Fractals》 被引量: 11发表: 2009年 The Formation of the Solar System. The study of the origin and evolu...
solar system-the Sun as well as all of the planets, satellites,asteroids, and comets—formed from a vast, rotating cloud of gas and dust called the solarnebula. ln the modern version of their theory, the solar nebula is thought to have had a mass somewhat greater than that of our ...

First models by Hoyle, Schatzman, Cameron were too simplified because there was no theory of star formation, and could not explain main features of the solar system. Much moresuccessful was the study of formation of planets by accumulation of solid particles and bodies in a circumsolar ...
