Planets: celestial wanderers
Planets are celestial bodies which revolve around stars. They have sufficient mass so that Under the influence strength gravity purchase hydrostatic equilibrium (approximately spherical form) and clean neighborhood of its orbit from others objects. In Solnechnaya system eight planets: Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Planets vary By size, mass, composition, atmosphere And temperature. Earth - the only one planet, on which known life. People Always were interested planets...

Stars: celestial bodies
Stars are massive, self-luminous balls of hot gas, in which occur thermonuclear reactions. They differ in size, brightness, temperature and chemical composition. Closest to The star on Earth is the Sun. Thanks to him on our planet there is life. People are always were interested stars. They gave them names, merged into constellations and tried predict by him the future. Today we we know about stars much more than earlier. Scientists are studying them with the help telescopes and space devices...
