Arturo
16Alp Boo
Arturo is a K-type (Orange) star. It carries the designation 16Alp Boo.
Arturo lies approximately 36.7 light-years from Earth, placing it within the Sun's local stellar neighborhood. This relatively short cosmic distance means the light reaching us today departed the star only about 36 years ago.
Arturo is classified as a spectral class K star (K-type (Orange)) on the Harvard spectral classification system.
With an apparent magnitude of -0.05, Arturo is one of the brightest stars in the entire night sky. It is easily visible to the naked eye from virtually any location on Earth where it rises above the horizon, and it can even be glimpsed in moderate light pollution. Observers will note its orange hue, which corresponds to a B-V color index of +1.239.
