Proxima Centauri

The closest star beyond the Sun. Proxima Centauri is a red dwarf and is far smaller, cooler, and less massive than the Sun. Proxima Centauri produces frequent outbursts of X-rays — big flares that could be deadly if you flew too close. It also has a strong magnetic field due to the hot gases rising from the star’s core, cooling as it reaches the surface, then dropping back to the center.
