[1] Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. This measurement does not rule out a low mass stellar companion of spectral class M7. Based on parallax measurements obtained during the Hipparcos mission, it is approximately 37 light-years (11 parsecs) distant from the Sun.

[1] Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. The two stars are about 3.24 light-years apart,[19] and each would appear bright in the other's sky. [16] Consequently, the Chinese name for Eta Boötis itself is 右攝提一 (Yòu Niè Dī yī, English: "the First Star of the Right Conductor"). Red-band image from the Second Digitized Sky Survey (DSS2), measuring 30 arcminutes across. Sarà la primavera! Eta Boötis appears close to the prominent star Arcturus (Alpha Bootis) in Earth's sky, and Arcturus is in fact its closest stellar neighbor, as both stars are nearly identical in distance from the Sun. From Virginia Beach , Muphrid will become visible around 20:38 (EDT) as the dusk sky fades, 35° above your western horizon.It will then sink towards the horizon, setting at 23:42. VIII. Arcturus would appear as roughly magnitude -5.2 (about 120 times brighter than it appears from Earth, or close to twice the brightness of Venus) in the night sky of a hypothetical planet orbiting Eta Boötis, while Eta Boötis would appear at about magnitude −2.4 (absolute magnitude −2.41 at 0.99 parsec) in the sky of a hypothetical planet orbiting Arcturus, or over twice the brightness of Sirius in the night sky.

The two stars are about 3.24 light-years apart,[19] and each would appear bright in the other's sky. [10], Eta Boötis bore the traditional names Muphrid and Saak. (As part of a binary pair, they are also designated Eta Boötis A and B, respectively.) XD, Bello,e molto curato,questo disegno di Abadir...ehm...Isaac.Complimenti,bel lavoro. Settled within a few months of the colonization of the nearby world of Thorin, Muphrid was one of the first worlds to be colonized by humanity. "Ca II HK emission in rapidly rotating stars. The WGSN decided to attribute proper names to individual stars rather than entire multiple systems. This measurement does not rule out a low mass stellar companion of spectral class M7. [15], In Chinese, 右攝提 (Yòu Niè Dī), meaning "the Right Conductor", refers to an asterism consisting of Eta Boötis, Tau Boötis and Upsilon Boötis.

În fapt, raportul său fier supra hidrogen este considerat ca aproape de limita superioară pentru stelele din discul galactic.

I know that there's mistakes (due to my lack of confidence with the colors and even with the drawing (I could see them now after some weeks, Grazie carissimo! Arcturus would appear as roughly magnitude -5.2 (about 120 times brighter than it appears from Earth, or close to twice the brightness of Venus) in the night sky of a hypothetical planet orbiting Eta Boötis, while Eta Boötis would appear at about magnitude −2.4 (absolute magnitude −2.41 at 0.99 parsec) in the sky of a hypothetical planet orbiting Arcturus, or over twice the brightness of Sirius in the night sky. © Dominic [2] In fact the ratio of iron to hydrogen is considered close to the upper limit for dwarf stars in the galactic disk.[18].

The estimated age of this star is about 2.7 billion years. [8], As a constituent of a double pair, Eta Boötis is also designated WDS J13547+1824A, with its two components being designated Aa (formally named Muphrid /ˈmjuːfrɪd/, the traditional name for the entire system)[9] and Ab. ; Based on the spectral type (G0IV) of the star, the star's colour is yellow .

[5], Eta Boötis presents as a subgiant that has begun the process of evolving from a main sequence star into a red giant. Muphrid is a main star in the constellation Bootes and makes up the constellation outline. Thanks to its high brightness, Muphrid is clearly visible when observed from locations with dark skyes, and should be also quite easily visible from light polluted areas.

With an apparent magnitude of 3.03, it is the fourth brightest star in Boötes, after Arcturus, Izar and Muphrid. Muphrid is an agricultural, nonindustrial world still lacking adequate means to expand its economy.. As an agricultural world, this world is a near-ideal environment for producing quality foodstuffs of plant, animal, and other forms. It has about 1.7 times the mass of the Sun and 2.7 times the Sun's radius. Arcturus ar avea o magnitudine de -5,2 (de circa 120 de ori mai strălucitoare decât văzută de pe Terra, adică aproape de două ori mai strălucitoare decât planeta Venus observată de pe Pământ) pe cerul nocturn al unei planete ipotetice pe orbită în jurul stelei Muphrid, în timp ce Muphrid ar avea o magnitudine de -2,5 pe cerul unei ipotetice planete pe orbită în jurul lui Arcturus, adică de două ori mai strălucitoare decât steaua Sirius observată de pe cerul nostru nocturn.
