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]
