Dirk:

1 light year = 9.46 X 10^15 meters or 9.46 x 10^12 km. So, in 50 years:

4.7 x 10^14 km (470 trillion kilimeters). That is within range of a lot of
stars.

There are a 100 stars within 7.63 parsecs (almost 25 light years), so if
you double the distance, there are about 800 stars (star systems) that
have "heard" from Sputnik!
