Procyon A is a yellowish-white star somewhat larger and 7.5 times brighter than the Sun, of spectral type F.
PROCYON (Alpha Canis Minoris). The eastern anchor of the Winter Triangle, Procyon is the luminary of Canis Minor, the smaller dog, and at magnitude zero (0.34) is the sky's eighth brightest star. At a distance of only 11.
Procyon is the Greek name for Alpha Canis Minoris from the earliest times. In English the meaning of the Greek roots would be something like "Before (or in Front of?) the Dog.
Procyon is a genus of nocturnal mammals, comprising three species commonly known as raccoons, in the family Procyonidae.

Canonical
The Canonical Approach to dynamics refers to the scheme in which the basic constituent is a space of states and the evolution of the system is described by a curve in this space parametrized by time.
Notice that Procyon is dimmer than Sirius so it has a larger value for the magnitude. (Don't let Sirius' negative value fool you. Just think of it as a number line, including negative values for Sirius, and you'll see what I mean.) ...

Class G
Class G stars are probably the best known, if only for the reason that our Sun is of this class. Most notable are the H and K lines of Ca II, which are most prominent at G2.
is now subdivided into " Procyon," " Solar " and " Arcturian " stars. The " Procyon " or calcium stars form a transition between Type I. and Type II. proper, and show the lines of calcium besides those of hydrogen. An important variety of Type III.
[1537] alpha Canis Minoris or Procyon ("before the dog") is the seventh brightest star in the sky, with a magnitude of 0.34. It is a binary star system that consists of a white star, Procyon A, and a fainter star Procyon B, which is a white dwarf.
With the exception of Sirius and Procyon (&alpha Canis Minoris), the brightest stars in the sky are not the nearest stars. The nearest star, Proxima (V645 Centauri), in the Centaurus constellation, is 1.3 parsecs away.
The radiant, which is only a few degrees from Procyon, is sufficiently high for observation by about an hour after local midnight at the latitude of New Zealand.
Bright stars relatively close to us, such as Sirius, Procyon and Altair, would have markedly different sky positions. Sirius, for example, would become part of Orion, some 2° west of Betelgeuse, and shining a little dimmer than we know it, at âˆ'1.
The Winter Circle is an asterism"or pattern of stars"made up six bright stars in five different constellations: Sirius, Rigel, Betelgeuse, Aldebaran, Capella, and Procyon.
It is also enclosed on three sides by the bright stars of the Winter Triangle (Sirius, Procyon and Betelgeuse).
Like Sirius B, Procyon B is a white dwarf.
In 2003, astronomers announced that epsilon Indi was accompanied by a brown dwarf. It was later discovered that the brown dwarf was actually a binary system.
Going across the shoulders from Bellatrix to Betelgeuse finds Procyon in Canis Minor.

The most important class G star to humanity: our Sun. The dark area visible in the lower left is a large sunspot.
To find M50 draw a line between Sirius and Procyon; you'll find the cluster about a third of the way up from Sirius.
Sirius is the brightest star in the sky. Sirius B is a white dwarf, as is Procyon B. They have about the same mass as the Sun but are only about one fiftieth of its diameter.
One of the 3 that make up the "Winter Triangle" (Sirius, Procyon, and Betelgeuse). Its name comes from the Greek "before the dog", since it precedes the "Dog Star" Sirius as it travels across the sky due to Earth's rotation.
Father of modern astrometry, published first accurate stellar parallax, discovered orbital deflections of Sirius and Procyon from unseen white dwarfs.

The brightest star in Earth's night sky is Sirius, 8.7 light-years away. The binary system called Procyon is a bit farther at 11.2 light-years.
In order they are: Aldebaran (alpha Tau), Capella (alpha Aur), Castor (alpha Gem), Pollux (beta Gem), Procyon (alpha CMi), Sirius (alpha CMa), Rigel (beta Ori), Bellatrix (gamma Ori) and Betelgeuse (alpha Ori) ...
To the left are bright Pollux and Castor and above them Procyon in Canis Minor. From a dark sky the fuzzy patch of M 44 will be apparent, and is really the main distinguishing feature of this otherwise inconspicuous constellation.
Canis Minor can be found by looking above the constellation of Canis Major. The star Procyon, along with Sirius in Canis Major and Betelgeuse in Orion create the asterism known as the "Winter Triangle".
