HD 125658 is a candidate variable star[3] in the northern constellation of Boötes. 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.[12] The star's apparent magnitude has been reported to vary between 6.34 and 6.45, but this has not been confirmed.[3]
