This all answers can be only answered only through the study of earth's material in space i.e., asteroids. Asteroids have always fascinated scientists. Through research, it has been found that asteroids are formed early in our solar system's history–about 4.5 billion years ago. To study more about more asteroids scientist are sending robotic missions to learn more about asteroid orbits, surface composition, and even return samples to Earth for further evaluation.

Till now 3,657 Earth-size planets have been discovered that lies outside the solar system. Seven thousand galaxies consisting of billions of stars are still under study. Around 51 galaxies that are near to the milky way has been confirmed and still, the list is never-ending.

It seems that we have not done looking at even half of the universe. So, much is still left to know and discover. Space is such an amazing topic that it seems what we have known until now is still not enough. The journey of exploring space from setting the foot on the earth is still going on.
