How far away is Proxima Centauri in light-years?
Answer
4.24 light-years
The text explicitly states that Proxima Centauri resides a mere 4.24 light-years away from Earth, marking it as the immediate cosmic backyard for current exoplanet investigations. This measurement defines its status as the closest stellar neighbor to our own solar system. Distances measured in Astronomical Units (AU) relate to the distance between the Earth and the Sun, which is not the unit used here to define the separation between stellar systems, nor is the orbital period of Proxima b the correct spatial measurement.
