Solar System Solar System Is the star with the star at the center. And a planet (Planet) is a satellite orbiting around. When harsh environments To live Life happens on those planets or satellites of the planet itself is called the Moon (Satellite), astronomers believe. Among more than a hundred billion stars in the Milky Way galaxy. Must have a favorable solar system life. The solar system, our planet is certainly a family. Only very long distances than can be done to the world of entertainment. We are a system of sun (The sun) is the central planets (Planets) 9 stars, called planetary (Dr. means nine) sequentially from the end of Mercury, Venus, Earth, Mars, Jupiter. Saturn, Uranus, Neptune, Pluto (now reduced to just eight planets Pluto trap) and there's moon. The fortunate Each (Moon of sattelites), whereas only two are Mercury and Venus have no moons. Asteroids (Minor planets) Comets (Comets) meteorite (Meteorites), as well as dust and gas. Moving in orbit Under the gravitational influence From the Sun The size of the solar system Compared vast distance between Earth and the sun. Which has a distance of 150 million kilometers, or 1 au. (Astronomy unit) astronomical unit is the solar system at a distance as far as the orbit of Pluto, the planet is the smallest in the solar system, which is far a distance of 40 times the first. astronomical unit And yet far away Dong comet until around Ottawa (Oort's Cloud), which may be up to 500,000 times the distance from Earth to the sun. Sun's mass More than 99 percent of all the mass in the solar system. The rest of the matters to be mass. Objects that include Planet Asteroids, comets and meteorites, including dust and gas. Each floating between planets with gravity (Gravity) is a solar system to control objects on the sky. Moving to legitimate force. Newton's gravity. Sun energy spread out with approximately. 90,000,000,000,000,000,000,000,000 Calories per second The energy generated by the nuclear reaction thermostat. By turning hydrogen into helium A source of heat to the stars. Planets Although the sun Hydrogen is a waste of time to reach 4 million tons per second. But scientists still have faith that the sun will continue to spread out energy at a rate that is equal for several billion years.
