15% shrinkage in 15 years, and accelerating.

I want to know what the acceleration rate is. I am also concerned
about possible EMP effects on Earth and on objects in orbit.

As of 500+ years ago, it already did its helium flashover.

Is that the closest red supergiant to us?

Well, this list lists the 26 nearest stars to us, and Betelgeuse isn't
on that list.

According to Wikipedia, it's only 600 ly's away. So it's certainly a
candidate for the closest red supergiant.

Antares is also a red supergiant, and a similar distance away.
