Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.

The clingy planet orbits so close to its star, it triggers powerful explosions of radiation that eat away at its atmosphere.

Solar flares measured around X1 — like the May 13 and 14 events — indicate strong flare intensity. An X10 flare is described as as a severe event, according to NOAA.

Solar flares are ranked on a scale from A to X, Space.com reports, with X-class flares being the most powerful and each rank up represents a tenfold increase in strength.

Solar flares are classified based on their strength, much like earthquakes, according to NASA.The scale ranges from B-class on the lowest end to C-class, then M-class, and finally, X-class.
