MOST satellite Icarius was a follower of the god Dionysus, who taught him to make wine. The Right Ascension (Longitude) is expressed in time (hh:mm:ss) and is how far along Earth's celestial equator the star is. As the Earth is titled, we therefore have Celestial and Ecliptic hemispheres and they can be different for a star. The White Dwarf would most probably have been a star much like our own, the Sun before it had come to the end of its life having used up all its fuel. Representing the smaller dog following Orion, the Hunter, Canis Minor is one of the smaller constellations, only the 71st in size. The questionnaire explored .

The Chinese know Procyon as the Third Star of South River (). Globular Star Cluster - A ball-shaped group of several thousand old stars. Based on the spectral type as we don't have the exact temperature', we can deduce that the surface temperature of the star is in the order of 6,000 and 7,500K based on the notes from Harvard University. Are We Alone? The Greeks associated Procyon with Maera, a hound that belonged to Erigone, the daughter of Icarius of Athens in Greek mythology. The physical distance between them varies between 8.2 and 31.5 astronomical units. As the names of the asterisms suggest, the best time of year to observe these stars is during the northern hemisphere winter, when the asterisms dominate the evening sky. The star is rapidly evolving off the main sequence, with its high luminosity suggesting that it has nearly converted all of its hydrogen into helium, and is thus moving into the sub-giant class. "main The star is believed to have spent about 680 million years on the main sequence, fusing hydrogen in its core, before evolving into a giant, losing most of its mass due to stellar winds, and ending its life cycle about 1.19 billion years ago, when it became a white dwarf. Henry Draper was an American doctor who started the list that has been expanded over the years. Procyon B If you use the 1997 parallax value, Procyon' absolute magnitude is 2.68. spectrum difficult (For an illustrated discussion, [28] Unlike the MOST result, the variation seen in the WIRE photometry was in agreement with radial velocity measurements from the ground. Previous estimates of the orbital elements of this binary system [40], Rarer names are the Latin translation of Procyon, Antecanis, and the Arabic-derived names AlShira and Elgomaisa. 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.
