Our solar system consists of an average star we call the sun, the planets Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune and Pluto. It includes also the satellites of the planets; numerous comets, asteroids, and meteoroids. The moon is the satellite rotating around the earth and the closest body to it.
The Sun is the richest source of electromagnetic energy ( mostly in the form of heat and light) in the solar system. The sun’s nearest known stellar neighbour is a red dwarf star called Proxima Centauri, at a distance of 4.3 light years away. The whole solar system, together with the local stars visible on a clear night, orbits the centre of our home galaxy, a spiral disk of 200 billion stars we call the Milky Way.
The nearest large galaxy is the Andromeda Galaxy. It is a spiral galaxy like the Milky Way but is 4 times as massive and is 2 million light years away. Our galaxy, one of billions of galaxies known, is traveling through the intergalactic space.
The planets, most of the satellites of the planets and the asteroids revolve around the sun in the same direction, in nearly circular orbits in a counter-clockwise direction. Pluto is a special case in that its orbit is the most highly inclined (18 degrees) of all the planets. Because of this, for parts of its orbit Pluto is closer to the sun than is Neptune. The axis of rotation for most of the planets is nearly perpendicular. The exceptions are Uranus and Pluto, which are tipped on their side.
