The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers

Formation of Our Solar System

Our own Sun and Solar System formed in an environment similar to this. Image credit: NASA, ESA and L. Ricci (ESO). Our Earth formed, along with the Sun and the rest of the Solar System, approximately 4.6 billion years ago, from a cloud of gas and space dust known as a nebula. Astronomical observations have revealed huge numbers of nebulae, as

History of Solar System formation and evolution hypotheses

The most widely accepted model of planetary formation is known as the nebular hypothesis.This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.Many stars, including the Sun, were formed within this collapsing cloud.The gas that formed the Solar System was slightly more

About how long ago did our solar system start to form? about 5

The process for the formation of our solar system started approximately 4.5 billion years ago with a spinning cloud of gas and dust called the solar nebula. Over time, matter in this cloud gathered to form the various bodies of our current solar system. Explanation: The solar system is believed to have begun forming approximately 4.5 billion

Solar System Timeline

How did our solar system come to be, and when did key events that led to life on Earth occur? At least Uranus and Neptune form closer to the Sun than where they are today. One or more ice giants may have also formed that were later ejected from the solar system. 4.55 billion years ago: Let there be light: The Sun begins fusing hydrogen into

How the Earth and moon formed, explained

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. and moon formed is important for piecing together the history of the solar system and answering questions like how long planets take to form, what planets are made of, and what makes a planet suitable for life. But the final stage of

A Timeline for Planet Formation

timeline for the formation of our solar system. Our solar system began as a collapsing cloud of gas and dust over 4.6 billion years ago. Over the next 600 million years, called by geologists the Hadean Era, the sun and the planets were formed, and Earth''s oceans were probably created by cometary impacts. Comets are very rich in water ice.
