But we''re not ashamed of pure nostalgia, either! It''s natural, it''s warm human nature, to lavish the most love on the most lovable things. And the Solar System of Burroughs, Brackett, Hamilton, Lewis et al. was a gorgeous scene..

Today, we know that our solar system is just one tiny part of the universe as a whole. Neither Earth nor the Sun are at the center of the universe. However, the heliocentric model accurately describes the solar system. In our modern view of the solar system, the Sun is at the center, with the planets moving in elliptical orbits around the Sun.

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

The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it.

Solar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries. While they often showed relative sizes, these models were usually not built to scale. The enormous ratio of interplanetary distances to planetary
Geocentric model, any theory of the structure of the solar system (or the universe) in which Earth is assumed to be at the center of it all. The most highly developed geocentric model was that of Ptolemy of Alexandria (2nd century CE). It was generally accepted until the 16th century.
Nicolas Copernicus (1473–1543) was a Polish scholar who reconstructed Ptolemy''s model of the Universe. Over the 1200 years since Ptolemy''s model was put forward, it had been developed into a complex and cumbersome mathematical system. Copernicus was able to simplify it by switching from an Earth-centred model to a Sun-centred one.
The solar system is also known as a planetary system. Since the 1990s scientists have found many planetary systems beyond our solar system. In these systems, one or more planets orbit a star—just as the eight planets in our solar system orbit the Sun. These planets are called extrasolar planets.
