At last, with interplanetary travel, instruments can be carried to many solar system objects, to measure their physical properties and dynamics directly and at very close range.
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as
The Solar System is an ordered system, as are 37% of observed systems. Similar systems however are the majority, comprising 59% of observed systems, while mixed systems
Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with more than 400 known planetary satellites; many asteroids, some with their own
Direct motion occurs when a planet appears to move in the same direction as the Sun, which rises in the east and sets in the west. This eastward movement is not a true reflection of the planet''s
Direct solar water heating systems pass potable water through the thermal collector that eventually flows directly to the desired application (the faucet, the showerhead, etc.).

The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets (including Earth), with the remainder
