Procyon
Procyon (α CMi, α Canis Minoris, Alpha Canis Minoris; BrE /ˈproʊsi.ɒn/;PRO-see-on) is the brightest star in the constellation Canis Minor. To the naked eye, it appears to be a single star, the eighth brightest in the night sky with a visual apparent magnitude of 0.34. It is classified as a binary star system, consisting of a white main-sequence star of spectral type F5 IV–V, named Procyon A, and a faint white dwarf companion of spectral type DQZ, named Procyon B.
The reason for its brightness is not its intrinsic luminosity but its relative closeness to the Sun. As determined by the European Space Agency Hipparcos astrometry satellite, it lies at a distance of just 11.46 light-years (3.51 parsecs), and is therefore one of our nearest stellar neighbours. Its closest neighboring star is Luyten's Star, about 1.12 ly (0.34 pc) away, and the latter would appear as a visual magnitude 2.7 star in the night sky of a hypothetical planet orbiting Procyon.
Visibility
Procyon is the eighth brightest star in the night sky, culminating at midnight on January 14. It forms one of the three vertices of the Winter Triangle asterism, in combination with Sirius and Betelgeuse. The prime period for evening viewing of Procyon is in late winter.
PROCYON
PROCYON (Proximate Object Close flyby with Optical Navigation) is an asteroid flyby space probe that was launched together with Hayabusa 2 on 4 December 2014 13:22:04 (JST). It was developed by University of Tokyo and JAXA. It is a small (70kg, approx. 60 cm cube), low cost (¥500 million) spacecraft.
It was intended to flyby the asteroid 2000 DP107 in 2016, but the plan was abandoned due to the malfunction of the ion thruster.
Mission overview
PROCYON was launched as secondary payload together with the Hayabusa 2 asteroid landing probe. After separation from the carrier rocket, PROCYON was left on a heliocentric orbit. On February 22, 2015, the ion engine was started, with the intention of adjusting the orbit so that an Earth flyby in December 2015 would direct the probe towards asteroid 2000DP107. Initial results were favourable - the engine delivered 330 µN of thrust rather than the designed 250 µN - but unfortunately the engine failed on March 10 and could not be restarted; PROCYON flew past Earth on December 3, 2015, but was unable to make a controlled orbit change.
Procyon (genus)
Procyon is a genus of nocturnal mammals, comprising three species commonly known as raccoons, in the family Procyonidae. The most familiar species, the common raccoon (P. lotor), is often known simply as "the" raccoon, as the two other raccoon species in the genus are native only to the tropics and less well known. Genetic studies have shown that the closest relatives of raccoons are the ring-tailed cats and cacomistles of genus Bassariscus, from which they diverged about 10 million years ago.
General attributes
Raccoons are unusual, for their thumbs (though not opposable) enable them to open many closed containers (such as garbage cans and doors). They are omnivores with a reputation for being clever and mischievous; their intelligence and dexterity equip them to survive in a wide range of environments and are one of the few medium-to-large-sized animals that have enlarged their range since human encroachment began (another is the coyote). Raccoon hindfeet are plantigrade similar to those of humans and bears. Raccoons are sometimes considered vermin or a nuisance. They have readily adapted to urban environments (compare urban opossums, skunks and foxes), scavenging garbage bins and other food sources.
