WASP-60 is a F-type main-sequence star about 1420 light-years away. The stars age is much younger than the Sun's at 1.7{{±|0.5}} billion years. WASP-60 is enriched in heavy elements, having 180% of the solar abundance of iron. The star does not have noticeable starspot activity, an unexpected observation for a relatively young star. The age of WASP-60 determined by different methods is highly discrepant though, and it may actually be an old star which experienced an episode of spin-up in the past.{{citation|arxiv=1406.4402|title=Discrepancies between isochrone fitting and gyrochronology for exoplanet host stars?|year=2014|doi=10.1093/mnras/stu950|last1=Brown|first1=D.

The star was named Morava in 2019 by Serbian amateur astronomers as part of the NameExoWorlds contest, after the Morava River in Serbia.[https://www.star-facts.com/star-names/ Star Facts Stars: A guide to the night sky Home Brightest Stars Star Names Star Names]

A multiplicity survey in 2015 did not detect any stellar companions to WASP-60.{{citation|arxiv=1507.01938|title=A Lucky Imaging search for stellar companions to transiting planet host stars|year=2015|doi=10.1051/0004-6361/201424091|last1=Wöllert|first1=Maria|last2=Brandner|first2=Wolfgang|last3=Bergfors|first3=Carolina|last4=Henning|first4=Thomas|journal=Astronomy & Astrophysics|volume=575|pages=A23|bibcode=2015A&A...575A..23W |s2cid=119250579}}

Planetary system

In 2012 a transiting hot Jupiter planet b was detected on a tight, circular orbit.{{citation|arxiv=1211.0810|title=WASP-52b, WASP-58b, WASP-59b, and WASP-60b: Four new transiting close-in giant planets|year=2012|doi=10.1051/0004-6361/201220363|last1=Hébrard|first1=G.|last2=Collier Cameron|first2=A.|last3=Brown|first3=D.
