We live in a tiny and insignificant part of the universe, which, nevertheless, is the home in which we were born and grew up. It's worth to visit and get to know our small solar neighborhood. Because if we are not aware of the facts of our solar system, if we do not know the planets that consist our neighborhood, it's like living in a house and knowing nothing about the other houses around ours. So, fasten your seat belts and enjoy the magnificent ride.
Can we find any trace of extraterrestrial life? And, if we do happen to discover another civilization, can we communicate with them? Every year, millions of small meteorites fall onto the Earth. Might there were some tiny alien life hitching a ride aboard the meteorite?But Earth isn't the only planet in the Solar System.
