| '''Eta Pegasi''' (η Peg) is a [[binary star]] in the [[constellation]] [[Pegasus (constellation)|Pegasus]]. It has the traditional name '''Matar''', which comes from the [[Arabic language|Arabic]] Al Saʽd al Maṭar (سعد المطر) meaning ''lucky star of rain''.<ref name=pa52_8/> The [[apparent visual magnitude]] of this star is +2.95,<ref name=clpl4_99/> making this the [[List of stars in Pegasus|fifth brightest member]] of Pegasus. Based upon [[parallax]] measurements, the distance to this star is about {{Convert|167|ly|pc|abbr=off|lk=on}}.<ref name=aaa474_2_653/>
| |
|
| |
|
| This system consists of a pair of stars in a binary orbit with a [[orbital period|period]] of 813 days and an [[orbital eccentricity|eccentricity]] of 0.183.<ref name=aj135_1_209/> The primary component is a [[bright giant]] star with a [[stellar classification]] of G2 II<ref name=apjss119_1_83/> and about four times the mass of the Sun.<ref name=aaa361_614/> The [[interferometry]]-measured [[angular diameter]] of this star, after correcting for [[limb darkening]], is {{nowrap|3.26 ± 0.07 [[milliarcseconds|mas]]}},<ref name=aaa431_773/> which, at its estimated distance, equates to a physical radius of nearly 18 times the [[Solar radius|radius of the Sun]].<ref name=lang2006/> It is radiating 247<ref name=an331_4_349/> times the luminosity of the Sun from its expanded [[stellar atmosphere|outer envelope]] at an [[effective temperature]] of 5,450 K.<ref name=an331_4_349/> The rotation rate of the star slowed as it expanded, so it has a [[projected rotational velocity]] of 1.7 km s<sup>–1</sup> with an estimated rotation period of 818 days.<ref name=aaa361_614/>
