[Firefly] How many planets are in the system?

The intro says that they left our solar system and found a new one with hundreds of earth's, but isn't that extremely unrealistic to have that many earth-like planets around one star?

Not just one system. It's a local cluster of star systems all within easy traveling distance of each other.

Also, most of the planets are *not* earth-like. They had to terraform many of them, and that's why living on the worse planets is so harsh.
