It is a hot [[giant star]] about 273 light years away.

One published spectral class, kA3hA4mF0, would identify HD 125658 as an [[Am star]], but this chemical peculiarity is considered doubtful.<ref name=renson2009/> The star's [[apparent magnitude]] has been reported to vary between 6.34 and 6.45, but this has not been confirmed.<ref name=cgcvs2004/>
