Even though it formally applies only to the primary component, it is also commonly used for the entire system and for its fainter component (Procyon B). Procyon A is a white main sequence star (F5IVV) about twice as big as the Sun, 1.4 times as massive, but with a significantly higher surface temperature of 6550K (11,300 degrees F), making it 6.9 times more luminous than the Sun. zone around Procyon A. R. Ciardullo (PSU), WFPC2, HST, NASA It is mainly the stars proximity and not its intrinsic brightness that makes it appear so bright to us. et al, 2005). The flyby velocity will be less than 10 km/s relative to the target asteroid. 3) PROCYON will perform a close flyby trajectory, with guidance provided by optical navigation and will pass within 50 km distance from the asteroid. Procyon A has a mass of 1.499 solar masses and a radius twice that of the Sun. broader than has been seen for other stars", and there is (Girard (Irwin Mass: Procyon A: 1.499 solar mass | Procyon B: 0.602 solar mass One parsec is the distance from the Sun to the star under consideration when the parallax angle is equal to 1 . In Greek mythology, Procyon is associated with Maera, a hound belonging to Erigone, daughter of Icarius of Athens. [35] The HRI X-ray pointlike source location is ~4 south of Procyon A, on the edge of the 90% confidence error circle, indicating identification with Procyon A rather than Procyon B which was located about 5 north of ProcyonA (about 9 from the X-ray source location).[34]. Mars will remain prominent all evening, despite the fact that it will continue to slowly fade in the days and weeks to come as it continues to gradually pull away from the earth. observed from Earth, but its intrinsic brightness actually [42] Consequently, Procyon itself is known as (Nn H sn, the Third Star of South River). MOST, The Inuit knew the star as Sikuliarsiujuittuq, which means the one who never goes onto the newly formed sea-ice. The name refers to a man who was too obese to go on ice to hunt and instead stole food from other hunters in his village. Identification is the number that the star was indexed in the Durchmusterung or Bonner Durchmusterung. See a discussion of Compared to Earth's mass of 5 x 10^24 kg, the Sun will lose considerably more mass due to fusion over its lifetime. The Procyon System is located about The orbital period is 41 years. Canis Minoris (Latinized to Alpha Canis Minoris) is the star's Bayer designation. Canis Procyon B appears years of Sol's current age and turn into a red giant before puffing Located at a distance of 860 light years from Earth, Rigel is the most distant star in the top 10 brightest stars list.

Distance, Size, and Mass. (b) 36.2 ly. When you look at Procyon, you are looking back in time and seeing how it looked years ago. H. Bond (STSci), Like many other bright and nearby stars, Procyon is often used in works of fiction (literature, films, television and video games). in 1951 have been superceded. As determined by the European Space Agency Hipparcos astrometry satellite,[16] this system lies at a distance of just 11.46 light-years (3.51 parsecs),[2] and is therefore one of Earth's nearest stellar neighbors. puts out more ultraviolet radiation than Sol. CSA The existence of Procyon B was first inferred in the 19th century. "main Procyon: Procyon is a binary star system consisting of an F-class star slightly larger than our sun and a white dwarf star that is currently degenerating. Procyon B, on the other hand, is much smaller than our sun - at 0.6 solar masses. However, Procyon B was not detected visually until For example, a red star can be large or small. than our Sun, Sol. Unlike Sol, it is a white-yellow main sequence dwarf star of spectral Procyon A and so evolved and "burnt out" even faster. The closest of these stars, Proxima Centauri, is just about 4.24 light . habitable Eventually it will swell up to anything between 80 and 150 times the diameter of the Sun somwhere between 10 million and 100 million years from now. On the other hand, white Procyon is a spectroscopic binary located in the constellation of Canis Minor, The Small Dog. This made Dionysus so angry that he unleashed a plague on Athens and inflicted insanity on all unmarried women in the city, who all hanged themselves, just like Erigone.
