Its apparent magnitude is 6.1,[2] meaning it can just barely be seen with the naked eye. Based on parallax measurements made by the Hipparcos spacecraft, it is located about 490 light-years (151 parsecs) away.[1] 59 Aurigae is a Delta Scuti variable, meaning it varies in luminosity due to pulsations on its surface. For that reason, it has been given the variable star designation OX Aurigae. The star's spectrum matches that of an F-type main-sequence star and it has a spectral type of F2V.[3] It is thought to be around 600 to 800 million years old, and has an effective temperature of 6808 K.[6] References1. ^1 2 3 4 5 {{cite journal|title=Validation of the new Hipparcos reduction|url=http://www.aanda.org/index.php?option=com_article&access=bibcode&Itemid=129&bibcode=2007A%2526A...474..653VFUL|author=van Leeuwen, F.|display-authors=etal|journal=Astronomy and Astrophysics|volume=474|issue=2|pages=653–664|date=2007|arxiv=0708.1752|bibcode=2007A&A...474..653V|doi=10.1051/0004-6361:20078357}} 2. ^1 {{cite journal|title=The Tycho-2 catalogue of the 2.5 million brightest stars|author=Høg, E.|display-authors=etal|date=2000|journal=Astronomy and Astrophysics|volume=355|pages=L27–L30|bibcode=2000A&A...355L..27H}} 3. ^1 {{cite journal|bibcode=1995ApJS...99..135A|title=The Relation between Rotational Velocities and Spectral Peculiarities among A-Type Stars|journal=Astrophysical Journal Supplement |volume=99|pages=135|author1=Abt|first1=Helmut A.|last2=Morrell|first2=Nidia I.|year=1995|doi=10.1086/192182}} 4. ^1 {{cite journal|author1=Mermilliod, J.-C.|title=Compilation of Eggen's UBV data, transformed to UBV (unpublished)|url=http://cdsads.u-strasbg.fr/cgi-bin/nph-bib_query?1986EgUBV........0M&db_key=AST&nosetcookie=1|date=1986|bibcode= 1986EgUBV........0M}} 5. ^{{cite journal|title=Pulkovo Compilation of Radial Velocities for 35 495 Hipparcos stars in a common system|author=Gontcharov, G.
