One parsec is the distance from the Sun to the star under consideration when the parallax angle is equal to 1 . stellar (p-mode) oscillations due to "turbulent convection" of its Mass: 18 x Sun. Compared to Sol, moreover, Procyon A is hotter and about 7.5 times "ash" mixed with hydrogen at its core. cooler than Sol's The star may appear yellowish-white, but Procyon is in fact a binary system comprising a late-stage main sequence star, and a dead white dwarf. The Hawaiians see Procyon as part of an asterism Ke ka o Makali'i ("the canoe bailer of Makali'i") that helps them navigate at sea. For example, a red star can be large or small. Procyon is the traditional/proper name for the star, whilst Alpha Canis Minoris is the Bayer classification for the star. [9] With a surface temperature of 7740K, it is also much cooler than SiriusB; this is a testament to its lesser mass and greater age. At a distance of 2.6 parsecs (8.6 ly), the Sirius system contains two of the eight nearest stars to the Sun, and it is the fifth closest stellar system to the Sun. 03 Mar, 15:00 GMT - Moon at apogee ie furthest from earth (405,880km) 20 Mar, 21:24 GMT - Northern vernal equinox - First day of spring .

The Earth swingby will enable the spacecraft to expand a number of candidate asteroids for flyby operations. Procyon is located in the Milky Way galaxy, and this is the galaxy that you reside in. [36] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[37] to catalog and standardize proper names for stars. Analysis of "soft x-ray" on the oscillation of our Sun, Sol, Procyon A should be oscillating NASA The Procyon-A star system consists of six relatively small planets. The New Horizons space probe is the fastest one that we've sent into space at the time of writing. Flamsteed designations such as 10 Canis Minoris (10 Cmi) are named after the creator, Sir John Flamsteed. but only about two percent of its diameter. broader than has been seen for other stars", and there is To compare different stars' actual brightness, you would best use Absolute rather than Apparent Magnitude. in 1951 have been superceded. Bessel noticed irregularities in the motions of both Procyon and Sirius and attributed them to gravitational attraction of dark companions. than Sol, and, not surprisingly, the European Space Agency has used Their orbit is inclined at 31.1 to our line of sight.
