According to the scientific consensus, the Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it.  Some scientists claim that all of this was formed from the collapse of a giant "molecular cloud" approximately 4.6 billion years ago.

[[Creation scientists]] reject this and have shown it was made by God less than 10,000 years ago.

A [[planet]] is defined as an object that orbits the [[sun]], is massive enough that its own gravity pulls it into a nearly round shape, and is dominant enough to clear away objects in its neighborhood. <ref>http://www.nasa.gov/vision/universe/solarsystem/planetsf-20060824.html</ref>  There are 8 planets in the solar system. They are, in order of increasing distance from the sun:<ref>The third grade</ref>

The first four planets are [[terrestrial planet]]s, the last 4 planets are jovian planets.  Terrestrial planets are small in size, have high densities, and consist of rocky materials. Jovian planets are large in size, have low densities, and consist of gaseous materials.

Jovian planets are large in size, have low densities, and consist of gaseous materials. In some cases, Uranus and Neptune are known as ice giants due to the large presence of gases heavier than hydrogen and helium.

A [[dwarf planet]] is an object that orbits the sun and has a round shape. The crucial difference between a planet and a dwarf planet is that a dwarf planet is not large enough to clear the neighborhood of its orbit. Currently recognized dwarf planets are:<ref>http://www.answers.com/topic/dwarf-planet</ref>

A [[dwarf planet]] is an object that orbits the sun and has a round shape, and was defined in 2006.
