SOLAR SYSTEM ASTERIODS & METERIODS MILKY WAY SATELLITES & MAN-MADE SATELLITES CONSTILATION COMITS ASTRONAUTS SOLAR SYSTEM There are eight planets, satellites and some other celestial bodies like asteroids and meteoroids form the solar system. We often call it a solar family, with the sun as its head. ASTERIODS & METERIODS METERIODS-the small pieces of rocks which move around the sun are called meteoroids. ASTERIODS-apart from the stars, planets and satellites, there numerous tiny bodies which also move around sun. these bodies are called asteroids. MILKY WAY There is a whitish broad band. Like a white glowing path across the sky on a clear starry night? is a cluster of million of stars. This band is the MILKY WAY GALAXY. our solar system is a part of this galaxy. SATELLITES & MAN-MADE SATELLITES SATELLITES-a satellite is a celestial body that moves around the planets in the same way as the planets move around the sun. MAN-MADE SATELLITES-a human made satellite is an artificial body. It is designed by scientists to gather information about the universe or for communication. CONSTILATION various patterns formed by different group of stars. These are called constellations. COMETS A comet is an icy, small Solar System body which, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail. These phenomena are both due to the effects of solar radiation and the solar wind upon the nucleus of the comet. ASTRONAUTS Those who study the celestial bodies and their movements are called astronauts.
