And there's moon. The misfortunes of life (Moon of sattelites), whereas only two planets Mercury and Venus have no moons. Asteroids (Minor planets) Comets (Comets) meteorite (Meteorites), as well as dust and gas. Which moves in orbit Under the influence gravity From the Sun The size of the solar system Vast more Compared distance Between the Earth and the Sun. The distance is about 150 million kilometers or 1au. (Astronomy unit) astronomical unit is the solar system, 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 one astronomical unit. And yet, far away Off the comet next to Dong (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 it is mass. Objects that include Planet Asteroids, comets and meteorites, as well as dust and gas. Each floating between planets with gravity (Gravity) is a solar control. All the objects in the sky The move follows the rules. The gravity of Newton. 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 star. planets Although Sun Hydrogen will be up to 4 million tonnes per second or more. But scientists believe there is a sun. Will continue to spread the power out at a rate that is equal for many billions of years,
people in ancient times to observe the sky and see the movement of the stars and think that these stars are stars that orbit indefinitely. For this reason, the ancient Greeks had a name for these stars that Planet (Planet - a planet), which means "the traveler" and respect for the planet that the gods are - Jupiter was Jove (Jupiter) King. my sisters - Venus is Mercury's (Mercury), god of communication - Venus is Venus (Venus), goddess of love and beauty - Mars is Mars (Mars), god of war - Saturn is. the Saturn (Saturn), god of agriculture, the father of Jupiter , and one of only five planets known in antiquity to be the only (not the world), it can be seen. With the naked eye are Mercury, Venus, Mars, Jupiter, Saturn, combined with the sun and moon, as well as seven lead on the seventh week and it stars the seventh, thus influencing the destiny of our people based on trust. astrological The other three planets are planets Uranus, Neptune, Pluto, was discovered later. But astronomers was named after the Greek goddess of. To comply with it
