The nearest star in Scorpius to Earth is Proxima Centauri, which is a part of the Alpha Centauri system. However, Proxima Centauri is not actually located within the constellation Scorpius, but rather in the constellation Centaurus.

While Proxima Centauri is the closest star to our Sun, it's still 4.24 light-years away from Earth. This means that it takes light from Proxima Centauri 4.24 years to reach us.
