The solar system
.The solar system is a system with the stellar center and planet (Planet) is a satellite orbit อยู่โดย around. When the environment conducive to life. The creatures will occur on those planets.(Satellite) astronomers believe. Among the stars all over the planet in the กาแลกซี่ทางช้างเผือก billion. The solar system to supporting life. The solar system that our world is the host live.We are a system, which consists of the sun (The sun) center. There are planets (Planets) 9 moon that เราเรียก that planets. (DR means nine) in chronological order, from the most are Mercury, Venus, earth, Mars, Jupiter, and Saturn.Neptune and Pluto (now no Pluto and only 8 moon)
.Also stars and moons of planets, each planet (Moon of sattelites) except for the two planets are Mercury, Venus, and not the host. The asteroid (Minor planets) comet (Comets) meteorites (Meteorites) as well as a group of dust and gas.Under the influence of gravity from the sun, the size of the solar system, vast, more than the distance between the earth and the sun, which is approximately 150 kilometres. Or 1AU.(Astronomy unit) astronomical unit is the solar system have a long distance to the orbit of Pluto, stars, planets with small. In the solar system, of which the far distance 40 times of 1 astronomical unit, and also far out.(Oort 's Cloud), which may be far away, 500000 times the distance from the earth to the sun. The sun with the mass percent more than 99 of mass in the solar system, all remaining
.There will be a mass of celestial bodies, which consists of planets, asteroids, comets and meteors, including gas and dust, floating between. Each planet by gravity (Gravity) is a force control of the solar system.According to the force of gravity moving Newton sun spread out with energy, rate of about 90000 000 000 000,,,,,,, 000 000 000 000 calories per second. As the energy generated from the reaction thermonuclear. By changing the hydrogen into helium. Which is the heat source to the stars, planets, even though the sun hydrogen will be 4 000 reach,,000 tons per second. But scientists are also a belief that the sun will continue to spread out at the rate of energy, as it has for a long time for billions of years.
