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.[2] 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.[4]

The star was named Morava in 2019 by Serbian amateur astronomers as part of the NameExoWorlds contest, after the Morava River in Serbia.[5]
A multiplicity survey in 2015 did not detect any stellar companions to WASP-60.[6]

Planetary system
In 2012 a transiting hot Jupiter planet b was detected on a tight, circular orbit.[7] The planet was named Vlasina by Serbian astronomers in December 2019, after the Vlasina River, a tributary of the Morava.[8]
Its equilibrium temperature is 1479±35 K.[2]
Measurement of the Rossiter–McLaughlin effect in 2018 revealed WASP-60b is on a retrograde orbit relative to the equatorial plane of the star, orbital obliquity equal to 129±17°.[2]
