Chapter 1: The Solar System
Our whole solar system, along with all the local stars you can see on a clear dark night, reside in one of our galaxy''s spiral arms, known as the Orion arm, as they orbit the supermassive
Structure and components of the Solar System | Space Physics Class
The Solar System, a cosmic neighborhood centered around our Sun, is a complex structure of planets, moons, and smaller bodies. From the rocky inner planets to the gas giants of the outer reaches, each
Solar System: Planets, Moons, and the Sun Explained
With each planet, moon, asteroid, and comet, the solar system tells a story of birth, destruction, rebirth, and motion—stories written in craters, frozen oceans, swirling storms, and
Solar System
Inside the Sun''s core hydrogen is fused into helium for billions of years, releasing energy which is over even longer periods of time emitted through the Sun''s outer layer, the photosphere. This creates the
Modeling the Structure of the Solar System – Science Lesson | NASA
A solar system is made up of a star and all of the objects that orbit it—planets, moons, asteroids, comets and meteoroids. Most stars host their own planets, so there are likely tens of
The Solar System: structural overview, origins and evolution
This chapter describes our current understanding of the key processes that shaped our planetary system, informed by empirical data such as meteorite measurements, observations of planet-forming

The Solar System is the gravitationally bound system of the Sun and the masses that orbit it, most prominently its eight planets, of which Earth is one. The system formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, creating the Sun and a protoplanetary disc from which the orbiting bodies assembled. Inside the Sun''s core hydrogen is fused into helium for billions of years, releasing energy which i
