HD 115088, also known as HIP 64951, is a star located in the southern circumpolar constellation Chamaeleon. It has an apparent magnitude of 6.33,[2] placing it near the limit for naked eye visibility. Based on parallax measurements from the Gaia spacecraft, the object is estimated to be 412 light years distant.[1] At that distance, its brightness is diminished by 0.37 magnitudes due to interstellar dust.[12]

HD 115088 has a stellar classification of B9.5/A0 V[3] — intermediate between a B9.5 and A0 main sequence star. It has 2.85 times the mass of the Sun[6] and double the radius of the Sun.[7] It radiates 62.5 times the luminosity of the Sun[8] from its photosphere at an effective temperature of 10,950 K,[6] giving it a bluish-white hue. It is estimated to be 244 million years old, having completed 52.5% of its main sequence lifetime.[1]
