[26][27], Photometric measurements from the NASA Wide Field Infrared Explorer (WIRE) satellite from 1999 and 2000 showed evidence of granulation (convection near the surface of the star) and solar-like oscillations. Procyon is (usually) the eighth-brightest star in the night sky and is located a distance of about 1.08 1014 km away from Earth. Distance (light years . They are separated by about 15 astronomical units (AU) on average or 15 times the Sun-Earth distance. Sirius, Alpha Canis Majoris ( CMa), is the brightest star in the night sky and one of the nearest star systems to Earth. Triangle" of first magnitude stars, whose other components are et al, 2008). Procyon B was bigger than Procyon A, so it burnt out faster, which means that once this star went through all processes that stars go, (main . Procyon lies at a distance of just 11.45 light-years / 3.51 parsecs away from the Sun. Procyon, Alpha Canis Minoris ( CMi), is a binary star system with an apparent magnitude of 0.34, located at a distance of only 11.46 light years from Earth in the constellation Canis Minor.Like its brighter neighbour Sirius in Canis Major, it is one of the nearest star systems to the Sun.It is mainly the star's proximity and not its intrinsic brightness that makes it appear so bright to us. For example, a red star can be large or small. (Kuchner Procyon distance from Earth is 11.41 light-years away from Earth or 3.50 parsecs. in Canis Minor, Procyon, Alpha Canis Minoris ( CMi), is the 18th nearest individual star to the Sun and the fourth closest visible star. The South River is an asterism formed by Procyon with Gomeisa (Beta Canis Minoris) and Epsilon Canis Minoris. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74.

A number represents a stars magnitude, whether apparent/visual or absolute. A binary star system, Procyon consists of a white-hued main-sequence star of spectral type F5IVV, designated component A, in orbit with a faint white dwarf companion of spectral type DQZ,[5] named Procyon B. (RECONS) The celestial hemisphere is equivalent to the hemispheres on Earth. [51] Procyon would be the brightest star in the night sky of an exoplanet orbiting Luyten's Star, with an apparent magnitude of -4.68. The Procyon System is located about 11.5 light-years (ly) from our Sun. Its eponymous name means "the one who never goes onto the newly formed sea ice", and refers to a man who stole food from his village's hunters because he was too obese to hunt on ice. et al, 2008). [3][22] Both the core and the envelope of this star are convective; the two regions being separated by a wide radiation zone. Procyon A and so evolved and "burnt out" even faster. The combined motions of the system across the sky means that in 323,140 years time, Procyon will become an eclipsing binary system for about 190 years when viewed from Earth, as its orbital plane crosses the Sun-Procyon line. The map was generated using Night Vision, a great free application by Brian Simpson. et al, 2000). ultraviolet Procyon is also the upper left member of the keep them burning, they gradually cool, redden, and fade away. Luminosity is the amount of energy a star pumps out relative to the amount that our star, the Sun, gives out. With twice the diameter of the Sun, Procyon is also the largest star within 25 light years. No oscillations were detected and the authors concluded that the theory of stellar oscillations may need to be reconsidered. Physical Properties of the Procyon System. The distance The B.D.
