The best time to observe the stars and deep-sky objects in the constellation of Persei is during the month of December. This planet is yet unconfirmed, yet some data suggests that if it exists, it would have around 6.6 times the mass of Jupiter. Capella is easy to identify because it is exceptionally bright and part of a hexagonal asterism formed by Auriga’s brightest stars with Elnath in Taurus. It is the only navigational star in Perseus. [12], This star, together with γ Persei, δ Persei, η Persei, σ Persei and ψ Persei, has been called the Segment of Perseus. In Chinese astronomy, Mirfak is part of an asterism called Celestial Boat, also formed by Gamma Persei, Delta Persei, Miram (Eta Persei), Mu Persei, Psi Persei, 48 Persei and HD 27084. The Miramar Ship Index for. which can be observed only with the help of very large telescopes. Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. Mirfak, Mirphak, Marfak, Algeneb, Algenib, α Persei, α Per, Alpha Per, 33 Persei, Monthly Notices of the Royal Astronomical Society, "Stellar Angular Diameters of Late-Type Giants and Supergiants Measured with the Navy Prototype Optical Interferometer", "Bulletin of the IAU Working Group on Star Names, No. is the number of times that the star is from the Earth compared to the Sun. The time it will take to travel to this star is dependent on how fast you are going. Tweet. Mirfak is a main star of the constellation outline. pulsator itself). The figure is derived at by using the formula from SDSS rather than peer reviewed papers. Mirfak has the stellar classification F5 Ib, indicating an evolved supergiant star appearing yellow-white in colour. The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. This star is huge and quite massive, having 8.5 solar masses, or 850% of our Sun’s mass, and 68 solar radii, or 6,800% of our Sun’s radius. With an effective temperature of 6,350 K, it is about 5,000 times more luminous than the Sun. In addition to the Alpha Persei Cluster, Perseus contains several other notable deep sky objects. This star is more than 5,000 times brighter than our Sun, having an apparent magnitude of 1.806, and an absolute magnitude of -5.1. Alpha Persei has an apparent visual magnitude of 1.8, and is a circumpolar star when viewed from mid-northern latitudes. Spectral standard stars are used as anchor points for the Morgan-Keenan (MK) system of stellar classification, used to classify stars based on their spectral features. In Hawaii, Mirfak is known as Hinali’i – it is associated with a tsunami and the start of the migration of Maui. Mirfak belongs to spectral class F5 and has a luminosity class of I corresponding to a supergiant star. The items in red are values that I've calculated so they could well be wrong. moving towards the Sun at the speed of 2 kilometers per second. It is the only navigational star in Perseus. This star is truly big, having 8.5 solar masses, and a whopping 68 solar radii. Mirfak is situated at around 510 light-years / 155 parsecs away from our Solar System. Finder chart. A different way to find Mirfak is using the stars of Cassiopeia’s W asterism. The estimated age of this cluster is between 50 to 70 million years. Procyon A is thus F5 IV,[19] a subgiant star. Thus, Mirfak is more than 100 times bigger than our Sun. Alpha Persei lies in the midst of a cluster of stars named as the eponymous Alpha Persei Cluster, or Melotte 20, which is easily visible in binoculars and includes many of the fainter stars in the constellation. The red arrow shows the motion of Mirfak during the next. Mirfak is a solitary star located at around 510 light-years away from our Solar System. Mirfak is an evolved supergiant star of spectral type F5 lb, appearing yellow-white in color. Thank you! [14] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[15] to catalog and standardize proper names for stars. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Exoplanets. instrumental in defining the nature of such stars (and may be a very modest Credit: Till Crener. The two stars are fainter than Alnair in Grus, Alnitak in Orion, and Alioth in Ursa Major, but they outshine Regor in Vela, Wezen in Canis Minor, and Kaus Australis in Sagittarius. The second star is Mirach, commonly used to find the Andromeda Galaxy (Messier 31) and Triangulum Galaxy (Messier 33), and the third one is Almach. Perseus is the 24th largest constellation in the sky, occupying an area of around 615 square degrees. in the constellation of Information regarding Metallicity and/or Mass is from the E.U. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. Mirfak is relatively easy to find because it is located near several familiar patterns of stars. Thanks to its high brightness, Mirfak is clearly visible when observed from locations with dark skyes, Apparent Magnitude is also known as Visual Magnitude. The surface gravity on Mirfak is at around 1.90 cgs. The source of the info is Simbad.
