Most of the material was pulled toward a central point: nearly all of the solar system''s mass—99.8%—is in

Binary star

OverviewDiscoveryEtymologyClassificationsOrbital periodDesignationsEvolutionAstrophysics

A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved as separate stars using a telescope, in which case they are called visual binaries. Many visual binaries have long orbital periods of several centuries or millennia and therefo

Chapter 1: The Solar System

The solar system consists of an average star we call the Sun, its "bubble" the heliosphere, which is made of the particles and magnetic field emanating from the Sun - the interplanetary medium - and objects that orbit the Sun: from as close

Circumbinary planet

The first circumbinary planet around a main sequence star was found in 2005 in the system HD 202206: a Jupiter-size planet orbiting a system composed of a Sun-like star and a brown dwarf. [6]HD 202206 is a Sun-like star orbited by two objects, one of 17 M J and one of 2.4 M J.The classification of HD 202206 b as a brown dwarf or "superplanet" is now clear.
