The amateur hobby of humanity since the dawn of time and scientific study of celestial objects. Because the planet Venus would find itself orbiting inside Mebsuta’s 4600 degree C temperature photosphere! The second magnitude primary, Gamma1, is a bright giant K star with a surface temperature of about 4,500 K, a luminosity of about 2,000 Lsun, and a radius of 80 Rsun - … The source of the information if it has a Hip I.D. If you need the diameter of the star, you just need to multiple the radius by 2. Hope you do more. The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. It is a shell star, surrounded by material expelled by its rapid rotation. Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2. If you want that in miles, it is about 1,107,650,592,815,255.80, based on 1 Ly = 5,878,625,373,183.61 miles. Known as Asellus Borealis "northern donkey", Gamma Cancri is a white-hued A-type subgiant of spectral type A1IV and magnitude 4.67, that is 35 times as luminous as of the Sun. Iota Cnc A shines with the light of 215 Suns from a 5000 Kelvin surface, while fainter "B" glows at 16 Suns from an 8800 Kelvin surface. The Sun's radius is 695,800km, therefore the star's radius is an estimated 710,739.41.km. The zodiac has twelve constellations (which are defined areas of the celestial sphere). The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. In 2007, Hipparcos data was revised with a new parallax of 11.69000 which put Iota Cancri B at a distance of 279.01 light years or 85.54 parsecs. Deg. RA (J2000): 08h 46’41.83” declination: +28d 45’36.0” Included in the Astronomical League’s certificate list of 100 double stars. Iota Cancri is probably not very well studied. Using the 2007 distance, the star is roughly 17,643,768.58 Astronomical Units from the Earth/Sun give or take a few. A temperature map of 55 Cancri e (in Kelvin; subtract 273 to get Celsius). It is a binary star composed of a yellow G-type bright giant and an A-type main sequence dwarf. Very close. The red dot in the diagram below shows where ι Cancri is situated in the Hertzsprung–Russell diagram. Hipparcos was a E.S.A. Delta Cancri also makes it easy to find X Cancri, the reddest star in the sky. RA (J2000): 08h 46’41.83” declination: +28d 45’36.0” Included in the Astronomical League’s certificate list of 100 double stars. Exoplanets. Born in … The information was obtained as of 12th Feb 2017. The colors of visual stars range from blue-white (stars with high-surface temperatures) to red (stars with low-surface temperatures). Helligkeit 9,8, 12,9m Flächenhelligkeit. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. The star is moving -46.36 ± 1.66 milliarcseconds/year towards the north and -22.74 ± 2.75 milliarcseconds/year east if we saw them in the horizon. Colorful double star. All messages will be reviewed before being displayed. Finally, for the perseverant, there are a number of binary systems visible in the Beehive Cluster (see below). Iota Cancri Photo Bombed - posted in Double Star Observing: Interesting shot of Iota Cnc and visitor. [8] It spent much of its stellar life as a B-type main sequence star before expanding and cooling to its current state as it spent its core hydrogen. Nice looking shot. This classifications is the same as the Sun. 1) NGC2683 im Luchs: Nach kurzer Suche gefunden. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Although no orbit has been derived, the two stars show a large common proper motion and are assumed to be gravitationally related. The color of stars in the night sky reflects their surface temperature (there are a few exceptions like Carbon Stars, but these are rare). Delta Cancri also makes it easy to find X Cancri, the reddest star in the sky. Cancri: Aussprache / K æ n s ər /, Genitiv / k æ ŋ k r a ɪ / Symbolismus: die Krabbe: Richtiger Aufstieg: 07 h 55 m 19,7973 s - 09 h 22 m 35,0364 s: Deklination: 33.1415138 ° –6.4700689 ° Bereich: 506 sq. Cancer is named after the Latin word for crab, and it is represented by a crab in the zodiac. The brightest star in the constellation is normally given the Alpha designation, there are exceptions such as Pollux which is Beta Geminorum. The SIMBAD astronomical database provides basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system. The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 25.00000 km/s with an error of about 1.50 km/s . The figure is derived at by using the formula from SDSS rather than peer reviewed papers. Tuesday, April 11 – Today is the birthday of William Wallace Campbell.
