It is a giant star of the spectral type K2III[4] with an effective temperature of 4,638[14] kelvins. It is cooler, yet larger and brighter, than the Sun. It is also a suspected small amplitude variable star.[21] References1. ^1 {{citation | title=XHIP: An extended hipparcos compilation | last1=Anderson | first1=E. | last2=Francis | first2=Ch. | journal=Astronomy Letters | volume=38 | issue=5 | pages=331 | year=2012 | bibcode=2012AstL...38..331A | doi=10.1134/S1063773712050015 | arxiv=1108.4971 | postscript=. }} [1][2][3][4][5][6][7][8][9][10]2. ^1 2 {{citation | display-authors=1 | last1=Massarotti | first1=Alessandro | last2=Latham | first2=David W. | last3=Stefanik | first3=Robert P. | last4=Fogel | first4=Jeffrey | title=Rotational and radial velocities for a sample of 761 HIPPARCOS giants and the role of binarity | journal=The Astronomical Journal | volume=135 | issue=1 | pages=209–231 | date=January 2008 | doi=10.1088/0004-6256/135/1/209 | bibcode=2008AJ....135..209M | postscript=.}} 3. ^1 2 3 4 {{citation | display-authors=1 | last1=Maldonado | first1=J. | last2=Villaver | first2=E. | last3=Eiroa | first3=C. | title=The metallicity signature of evolved stars with planets | journal=Astronomy & Astrophysics | volume=554 | id=A84 | pages=18 | date=June 2013 | doi=10.1051/0004-6361/201321082 | bibcode=2013A&A...554A..84M | postscript=.|arxiv = 1303.3418 }} 4. ^1 2 {{citation | display-authors=1 | last1=Cenarro | first1=A.
