Xi1 Capricorni, Latinized from ξ1 Capricorni, is an orange-hued star in the constellation Capricornus. With an apparent visual magnitude of +6.34, [2] it is near the lower limit of brightness for stars that can be seen with the naked eye. Based upon an annual parallax shift of 5.26 mas as seen from Earth, [1] this system is located roughly 620 light-years from the Sun.
It is an evolved K-type giant star with a stellar classification of K0 III. [3] With an age of 3.35 billion years, this star has an estimated 1.55 [6] times the mass of the Sun and is radiating 139 [1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of about 4,439 K.
