The Sun is one of about 200 billion stars (or perhaps more) within the Milky Way Galaxy.

So far, astronomers have found more than 500 solar systems and are discovering new ones every year. It's estimated that there may be tens of billions of solar systems in our galaxy, perhaps even as many as 100 billion.

Our solar system is definitely not the only solar system in the Milky Way.


In recent years, satellites has discovered over 3,000 planets around nearby stars. It is now known that solar systems are a very common occurrence.

In fact our nearest neighbour star has planets. It is even possible that it can support life.

Our solar system is by no way unique. The formation of planets is a natural course of the evolution of a star. The chances of other solar systems in which life has evolved are high.
