The planets of the solar system mark time relatively close to the Sun compared to interstellar space. Pluto orbits the Sun at an average distance 40 times that of the Earth, yet the nearest star (the Alpha Centauri system) to the solar system is a mind-numbing 260,000 times the distance of the Earth to the Sun. ... 2008 Phil Plait. ...

... In addition to the planets and their satellites the solar system contains a large number of smaller but interesting objects. There are thousands of known asteroids and comets and undoubtedly many more unknown ones. ... There are also some asteroids whose orbits carry them closer to the Sun than the Earth (Aten, Icarus, Hephaistos). Most comets have highly elliptical orbits which spend most of their time in the outer reaches of the solar system with only brief passages close to the Sun. ...

... Kepler is a mission designed to detect and characterize Earth-sized planets around solar-like stars. The sizes of the planets are determined from the decrease in light from a star that occurs during planetary transits, and the orbital period is determined from the repeatability of the transits. ... These goals are accomplished by continuously and simultaneously monitoring a single field of 140,000 stars for evidence of brightness changes caused by transits of Earth-sized or larger planets. ...

In ancient times the solar system was thought to be the whole Universe, so the study of planetary motions was cosmology. ... The planets other than the Moon and Sun generally move West to East through the stars, but occasionally stop and move in the opposite direction ( retrograde motion). In order to explain the retrograde motion of the planets, the geocentric model of the Solar System shown above puts the planets on small circles called epicycles . ...

The artist's rendering depicts the multiple planet systems discovered by NASA's Kepler mission. Out of hundreds of candidate planetary systems, scientists had previously verified six systems with multiple transiting planets (denoted here in red). Now, Kepler observations have verified planets (shown here in green) in 11 new planetary systems. Many of these systems contain additional planet candidates that are yet to be verified (shown here in dark purple). ...
