I measured the change of brightness of the star RR Gem, and it is mind boggling.
RR Gem is an intrinsic variable star. And is intrinsic because internal physical processes change its radial size and opacity. It is, in other words, a pulsating variable star. Its formal type is RRab. This is an RR Lyr type of variable star, and most of them can be found in globular star clusters (that's why they are called cluster variables).
