The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. A simple colour correlation temperature fit gives temperatures around 3,749 K, while a full spectrum fit gives a temperature of 5,018 K.[13], The distance to RW Cephei has been estimated on the basis of its spectroscopic luminosity and is assumed to be a member of the Cepheus OB1 association at 3,500 parsecs, consistent with the parallax from Gaia Data Release 2. Colourwhite to yellow [17] Based on the same spectra it was adjusted to the standard star for type K2 0-Ia. Original cross was made on July 29, 2014 by Dale Thurber for Delectation of Tomatoes and selections made for enormous fruit size. Search for: Stars.

RW Cephei's Alternative Names HIP110504 is the reference name for the star in the Hipparcos Star Catalogue. Regular leaf vines are healthy and productive from 85 days. Your seeds will come from this 3+ lb. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. [21][7], The temperature intermediate between the red supergiants and yellow hypergiants, and itself varying considerably, has led to it being variously considered as a red hypergiant[22] or yellow hypergiant. [5] The General Catalogue of Variable Stars gives a period of approximately 346 days, but other studies suggest different periods and certainly no strong periodicity. RW Cephei adalah salah satu bintang yang paling istimewa karena merupakan satu-satunya superraksasa oranye yang dikenal. The Declination is how far north or south the star is compared to the celestial equator and is expressed in degrees. The location of the star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The source of the information if it has a Hip I.D. Exoplanets. Declination (Dec.)+55° 57` 47.6 Radial Velocity-56.00 ± 5.70 km/s References This page was last changed on 5 April 2019, at 03:09.

Physical Properties (Colour, Temperature, Radius) of RW Cephei as of 9-26-2017; more pictures will be posted as they become available after the official weigh off. A faint star will have a high number. [19][20] The temperature is equally uncertain, with contradictory excitation strengths in the spectrum. RW Cephei's Alternative Names Galactic Longitude103.20 degrees Location of RW Cephei The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. In the first MK spectral atlas, it was listed M0:Ia. The Id of the star in the … This star is another hypergiant, 1,500 times bigger than the sun, and reflects an orange color. In 2007, Hipparcos data was revised with a new parallax of 0.81 which put RW Cephei at a distance of 4026.71 light years or 1234.57 parsecs. BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The third largest star in the galaxy is the RW Cephei. satellite operation launched in 1989 for four years. The specimen pictured measured to 3.27 lbs. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever. Visual / Apparent Magnitude6.44 RW Cephei. GalaxyMilky Way Named after a hyper-giant star, RW Cephei is the result of a controlled cross between two giant tomato varieties: 1) Brutus Magnum, descended from 6.25 Meisner 2011; and Big Zac, from 4.57 MacCoy 2013, which was also the parent of the world record 8.41 MacCoy 2014. So the genetic heritage is here for some truly huge tomatoes for … It should not be taken as though the star is moving closer or further away from us. If you used the 1997 Parallax value, you would get an absolute magnitude of -3.18 If you used the 2007 Parallax value, you would get an absolute magnitude of -4.02. 840.34 Parsecs Spectral TypeG8Iavar Proper Motion Dec.-2.66 ± 0.29 milliarcseconds/year In the case of a star, its the galactic centre. RW Cephei is a hypergiant variable star in the constellation Cepheus, at the edge of the Sharpless 132 HII region and close to the small open cluster Berkeley 94. Alternative NamesRw Cep, Herschel`s Garnet Star, HD 212466, HIP 110504, BD+55 2737, RW Cep This means the star is a white to yellow supergiant star. [14], The spectral has been classified as early as G8 and as late as M2, but it isn't clear that there has been actual variation. RW Cephei adalah bintang superraksasa g8 yang dapat ditemukan di rasi bintang Cepheus dan juga bintang variabel, yang terletak sekitar 3.500 tahun cahaya dari Bumi dan berdiameter 1.535 jari-jari matahari. It is among the largest known stars with a diameter between 981 to 1,758 tmes larger than the Sun. Its variable/pulsating period lasts for 0.2 days (variability). Hipparcos was a E.S.A. The star has a B-V Colour Index of 2.21 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 590 Kelvin. [18] Molecular bands characteristic of M-class stars are seen in infrared spectra, but not always in optical spectra. In Greek mythology, Cepheus is a king who holds down the Pole Star, Polaris, with his foot. Variable Star TypeSlow Irregular RW Cephei RW Cephei SKU: $2.40. The primary star in the system, VV Cephei A, […] Read More. The smaller the magnitude, the brighter the star. When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. For RW Cephei, the location is 22h 23m 07.02 and +55° 57` 47.6 . Estimated Facts, Radius (x the Sun)1,535.00 Fruits are deep red with pronounced ribbing, as well as lobing with the larger specimens. It is purely that the distance was recalculated.

Multiple Star SystemNo / Unknown The star is one of the largest stars known with a radius nearly 1,600 greater than the Sun's. [15] RW Cep was later listed as the standard star for spectral type G8 Ia,[16] then as the standard for K0 0-Ia. RW Cephei Apparent and Absolute Magnitudes 2007 Distance from Earth0.81 Parallax (milliarcseconds) The Variable Type is usually named after the first star of that type to be spotted. RW Cephei is a white to yellow pulsating supergiant star that can be located in the constellation of Cepheus. Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 1.19 which gave the calculated distance to RW Cephei as 2740.87 light years away from Earth or 840.34 parsecs. $2.40. RW Cephei has an apparent magnitude of 6.44 which is how bright we see the star from Earth. ConstellationCepheus One of the largest stars known, RW Cephei's radius is more than 1,000 times that of the Sun (R ☉), thus larger than the orbit of Jupiter. RW Cephei has been calculated as 1,535.00 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,068,053,000.00.km.
