HD 32820, also known as HR 1651, is a yellowish-white hued star located in the southern constellation Caelum, the chisel. It has an apparent magnitude of 6.3, [2] placing it near the limit of naked eye visibility. The object is located relatively close at a distance of 103 light years based on parallax measurements from Gaia DR3, [1] but is receding with a heliocentric radial velocity of 29.8  km/s . [6]

HD 32820 has a stellar classification of F8 V, [3] [4] indicating that it is an ordinary F-type main-sequence star that is generating energy via hydrogen fusion at its core. It has 125% the mass of the Sun [8] and 133% of its radius. [9] It radiates double the luminosity of the Sun [1] from its photosphere at an effective temperature of 6,227  K . [9] HD 32820 is said to be 3.46 billion years old, [11] slightly younger than the Sun , and has a near solar iron abundance. [11] The star spins modestly with a projected rotational velocity of 8  km/s [12] and is chromospherically inactive [15]
