Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. []

Discovery and exploration of the Solar System

The Solar System is one of many planetary systems in the galaxy. [1] [2] The planetary system that contains Earth is named the "Solar" System. The word "solar" is derived from the Latin word for Sun, Sol (genitive Solis). Anything related to the Sun is called "solar": for example, stellar wind from the Sun is called solar wind.

Astronomy

Astronomy - Solar System, Planets, Stars: The solar system took shape 4.57 billion years ago, when it condensed within a large cloud of gas and dust. Gravitational attraction holds the planets in their elliptical orbits around the Sun. In addition to Earth, five major planets (Mercury, Venus, Mars, Jupiter, and Saturn) have been known from ancient times.

Formation and evolution of the Solar System

Artist''s conception of a protoplanetary disk. There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [1] Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other

Science 101: The Solar System

The solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed, resulting in a solar nebula, a swirling disc of material that collided to form the solar system. The solar system is located in the Milky Way''s Orion star cluster.

How do stars and planets form and evolve?

The Sun is the closest star to Earth, and the single most important influence on the worlds of the Solar System in terms of the light and particles it emits. Studying the Sun, in other words, helps us understand the habitability of Earth, but also other stars elsewhere in the universe.

The solar system itself is only a small part of a huge system of stars and other objects called the Milky Way galaxy. The solar system orbits around the center of the galaxy about once every 225 million years. The Sun. At the center of the solar system is a star called the Sun. It is the largest object in the solar system.

7.1 Overview of Our Planetary System

The central part of this cloud became the Sun, and a small fraction of the material in the outer parts eventually formed the other objects. Strictly speaking, then, there is only one solar system; planets orbiting other stars are in planetary systems. 2 An AU (or astronomical unit) is the distance from Earth to the Sun. 3 We give densities

Multiple Star Systems

Multiple Star Systems Our solar system, with its eight planets orbiting a solitary Sun, feels familiar because it''s where we live. But in the galaxy at large, planetary systems like ours are decidedly in the minority. More than half of all stars in the sky have one or more partners. These multiple star systems come []
