An impossible question to answer.

Explanation:

It is only within the last 20 years that astronomers have discovered planets outside our solar system. They have discovered about 715 planets revolving around 305 stars which means slight more than 2 planets per star.

Given that our medium size star has 8 full size planets revolving around it, it is not unreasonable to believe that the planets we have discovered have another 6 or 7 planets with them revolving around that one star.
