Yes you're correct! It's about a factor of 50,000 between the orbit of Jupiter and the distance to the nearest star.

But the orbit of Jupiter is still a lot bigger than the size of the Sun. To give numbers: The radius of the Sun is 700km, the radius of the orbit of Jupiter is 7*10^8 km (approx, it varies a bit), and the distance to the nearest star is 4*10^13 km.
