What is Kappa Delphinus

Kappa Delphini is a yellow G5 subgiant, almost a mature version of our own Sun: surface near 5,700 degrees, around 2.9 billion years old. At 98 light-years she journeys through the galaxy with a distant companion, an orange subgiant some 200 arcseconds away that shares her proper motion. She belongs to the Dolphin, one of the smallest and most precise constellations, a compact figure leaping over the Milky Way.
