Hang on, I thought 'Solar system' means the system orbiting the star 'Sol' i.e. our sun? Isn't the general term 'planetary system'?

Yes, 'Solar' refers to our sun, Sol. So there is only one 'Solar' system which is our own.

I think 'star system' is acceptable as well.

"The star is 2500 light years away from Earth." Found that on google. Doesn't seem so far away :P

Yeah, unreachable without FTL travel.

It would take about 15.6 years [0] to reach the star on a ship capable of a constant 1G acceleration.

Here is the explanation and equations: http://math.ucr.edu/home/baez/physics/Relativity/SR/rocket.h...
