19 Piscium
Scientific overview
19 Piscium is a star in the constellation Pisces (Piscium), lying about 898.5 light-years from Earth.
Class C (carbon star). Cool carbon stars — evolved red giants whose atmospheres hold more carbon than oxygen, giving them a striking deep-red, ruby colour. Such stars have surface temperatures around ≤ 3,200 K and appear deep red to the eye.
