Solar nebula | Formation, Accretion, Protoplanetary Disk | Britannica
2024年12月16日 · 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.
Nebular hypothesis - Wikipedia
It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets. The theory was developed by Immanuel Kant and published in his Universal Natural History and Theory of the Heavens (1755) and then modified in …
Mysteries of the Solar Nebula - NASA Jet Propulsion Laboratory …
2001年7月20日 · There is plenty of evidence from observations over many decades to establish the broad outlines of the story. But exactly how the placental cloud of dust and gas, called the "solar nebula," turned into the solar system that we see around us today still poses many mysteries for scientists.
How our solar system was born - Natural History Museum
Discover how a giant interstellar cloud known as the solar nebula gave birth to our solar system and everything in it. The solar system as we know it began life as a vast, swirling cloud of gas and dust, twisting through the universe without direction or form.
Formation and evolution of the Solar System - Wikipedia
In roughly 5 billion years, the Sun will cool and expand outward to many times its current diameter (becoming a red giant), before casting off its outer layers as a planetary nebula and leaving behind a stellar remnant known as a white dwarf. In the distant future, the gravity of passing stars will gradually reduce the Sun's retinue of planets.
How Was the Solar System Formed? – The Nebular Hypothesis
2016年6月1日 · When it comes to the formation of our Solar System, the most widely accepted view is known as the Nebular Hypothesis. In essence, this theory states that the Sun, the planets, and all other...

Solar Nebula - an overview | ScienceDirect Topics
The solar nebula refers to the rotating, flattened disk of gas and dust from which the solar system originated approximately 4.6 billion years ago. From: Treatise on Geochemistry (Second Edition), 2014
Scientists estimate solar nebula’s lifetime - MIT News
2017年2月9日 · By studying the remanent magnetizations in ancient meteorites, an MIT team has determined that the solar nebula — the vast of disc of gas and dust that ultimately gave rise to the solar system — lasted around 3 to 4 million years.
History of the solar nebula from meteorite paleomagnetism
We review recent advances in our understanding of magnetism in the solar nebula and protoplanetary disks (PPDs). We discuss the implications of theory, meteorite measurements, and astronomical observations for planetary formation and nebular evolution.
