Procyon B is the smaller white dwarf star. ... With an absolute magnitude of -7.84, if it were located at the same distance from us as Sirius, ... Procyon in Canis Minor and Sirius in Canis Major, the brightest star in the sky. Procyon A is the largest and the most luminous of the pair, being a large subgiant star 4 times larger than the Sun. Procyon's location is: Right ascension: 7 hours 39 minutes 18.1 seconds Apparent Magnitude is also known as Visual Magnitude. At a distance of only 11.4 light years, it is the 14th closest star system, which largely explains its brightness.. Procyon is the 8th brightest star in the sky. Star A has an absolute magnitude of 2.5 and star B has an apparent magnitude of 2.5, but star A is a main sequence star and star B is a red giant. If you used the 1997 Parallax value, you would get an absolute magnitude of 2.68 If you used the 2007 Parallax value, you would get an absolute magnitude of 2.67.

The Voyager 2 spacecraft, launched in 1977 to study the four giant planets in the Solar System, is expected to pass within 4.3 light-years (1.3 … The system consists of a white main sequence star of spectral type F5 IV-V, named Procyon A, and a faint white dwarf companion of spectral type DA, named Procyon B. Procyon or Alpha Canis Minoris (Alp CMi) is the brightest naked eye star in the constellation Canis Minor.With an apparent magnitude of 0.4, Procyon is the 8th brightest star in the entire sky (see: 50 Brightest Stars ).Its absolute magnitude is 2.68 and its distance is 11.4 light years.The Equinox J2000 equatorial coordinates are RA = 07h 39m 18.1s, Dec = +05° 13' 30". The Procyon system is composed of Procyon A, a white hydrogen-fusing dwarf of the spectral type F5 IV-V, and Procyon B, a much fainter white dwarf companion with the stellar classification DQZ. Procyon Apparent and Absolute Magnitudes. Rigel B. Rigel B has an apparent magnitude of 6.7, which would make the star easily visible in small telescopes if it were not so close to Rigel A.
Procyon (A.CMi) is a binary star system around 11.5 light-years away in the constellation of Canis Minor. Procyon, an aw designatit Alpha Canis Minoris (α Canis Minoris, abbreviatit Alpha CMi, α CMi), is the brichtest starn in the constellation o Canis Minor.. References The primary star of the system, Procyon A, has an apparent visual magnitude of 0.34, while the companion star, Procyon B, is an almost dead white dwarf with an apparent magnitude of 10.7, which makes it an exceedingly difficult target for amateur equipment. Procyon (α CMi, α Canis Minoris, Alpha Canis Minoris) is the brightest star in the constellation Canis Minor.To the naked eye, it appears to be a single star, the seventh brightest in the night sky with a visual apparent magnitude of 0.34. Procyon, also known as Alpha Canis Minoris or the Little Dog Star, is the brighter of the two stars that make up the constellation Canis Minor.Although appearing as a single star to the unaided eye, Procyon is actually a binary system made up of the primary star Procyon A and its white dwarf companion, Procyon B. Procyon, an aw designatit Alpha Canis Minoris (α Canis Minoris, abbreviatit Alpha CMi, α CMi), is the brichtest starn in the constellation o Canis Minor.

... With an absolute magnitude of -7.84, if it were located at the same distance from us as Sirius, ... Procyon in Canis Minor and Sirius in Canis Major, the brightest star in the sky. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. … Alpha Centauri (Latinized from α Centauri, abbreviated Alpha Cen or α Cen) is the closest star system and closest planetary system to Earth's Solar System at 4.37 light-years (1.34 parsec) from the Sun.It is a triple star system, consisting of three stars: α Centauri A (officially Rigil Kentaurus), α Centauri B (officially Toliman), and α Centauri C (officially Proxima Centauri).
