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 as the planet Mercury all the way out to comets almost a light-year away.A light year is the distance light travels in a year, moving at about
Andreas Cellarius''s illustration of the Copernican system, from the Harmonia Macrocosmica. Heliocentrism [a] (also known as the heliocentric model) is a superseded astronomical model in which the Earth and planets revolve around the Sun at the centre of the universe.Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center.
Copernican system, in astronomy, model of the solar system centered on the Sun, with Earth and other planets moving around it, formulated by Nicolaus Copernicus, and published in 1543. Unlike the older Ptolemaic system, it correctly described the Sun as having a central position relative to Earth and other planets.
