What is 3 Andromedae

3 Andromedae is a K-type orange giant at 177 light-years, hanging in the western reaches of the chained princess. Its light took a little less than the age of American independence to reach us —roughly two human lifetimes. It glows with the tired blush of an aged Sun, well past the prime of its main-sequence life.
