the earth which seem so big is only a very small part of the solar system.yet,although the solar system seems very large as we. consider the sun ,planet and moons,it is very small if we compare it to the galaxy to which it belongs. the solar systemis one small part of a star system,the milky way .it consits of about 40 billion stars. If you think about it, that's a whole lot of stars. To top that, there are untold trillions or quadrillions or quintillions of galaxies beyond our own. Each of those galaxies also is a giant cloud of stars traveling through the Universe. Imagine how many stars there must be across the whole Universe!
