Solar System

The rest of the Solar System is its eight major planets, five dwarf planets, hundreds of moons, and a large number of comets, asteroids, and other small bodies of rock and ice. The extent of the Solar System is defined by the solar wind — particles driven by the Sun''s magnetic field — and gravitational influence.

In Depth | Our Solar System – NASA Solar System Exploration

Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. 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 Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

Typical mid-latitude missions would experience a 25-hour cycle, with approximately 50 percent of the time spent under illumination. In practice, this means that a solar power system must be oversized to supply power

Scientists have theorized that during the Solar System''s formation, Mars was created as the result of a random process of run-away accretion of material from the protoplanetary disk that orbited the Sun. Mars has many distinctive chemical features caused by its position in the Solar System.
