Lambda Capricorni, Latinized from λ Capricorni, is a solitary [10] star in the southern constellation of Capricornus. It is faintly visible to the naked eye with an apparent visual magnitude of +5.56. [2] Based upon an annual parallax shift of 11.58 mas as seen from the Earth, [1] the star is located about 282 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.11 due to interstellar dust. [11]
This is a white-hued A-type main sequence star with a stellar classification of A1 V. [3] It is a magnetic Ap star, indicating the spectrum displays chemically peculiar features. [8] The star has an estimated 2.50 [6] times the mass of the Sun and about 2.2 [7] times the Sun's radius. It is 155 [6] million years old and is spinning rapidly with a projected rotational velocity of 192.5 km/s. [8] Lambda Capricorni is radiating 45 [5] times the Sun's luminosity from its photosphere at an effective temperature of 10,674 K. [6]
