The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"hd-32115","name":"HD 32115","class":"a9v_white_main_sequence_star","category":"star","object_type":"A9V white main-sequence star","mag":6.31,"mag_band":"V","abs_mag":2.832,"abs_mag_band":"V","distance_ly":161.7840003515917,"distance_method":"parallax","ra_deg":75.16587,"dec_deg":-2.066032,"epoch_ra_deg":75.504611,"epoch_dec_deg":-2.025976,"epoch_moved_arcsec":0.355,"pm_ra_mas_yr":-12.94,"pm_dec_mas_yr":-3.1,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Orion","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-32115","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"05007-0204","age_years":778835830,"companions":[{"measured":2010,"magnitude":20,"components":"AB","discoverer_code":"VIG   7","separation_arcsec":6.5,"position_angle_deg":309},{"measured":2010,"magnitude":21,"components":"AC","discoverer_code":"VIG   7","separation_arcsec":8,"position_angle_deg":99},{"measured":2016,"magnitude":14,"components":"AD","discoverer_code":"VIG   7","separation_arcsec":9.2,"position_angle_deg":329},{"measured":2010,"magnitude":22,"components":"AE","discoverer_code":"VIG   7","separation_arcsec":9.7,"position_angle_deg":29},{"measured":2010,"magnitude":19,"components":"AF","discoverer_code":"VIG   7","separation_arcsec":11.4,"position_angle_deg":174},{"measured":2010,"magnitude":19,"components":"AG","discoverer_code":"VIG   7","separation_arcsec":13.6,"position_angle_deg":73}],"mass_solar":1.51,"radius_solar":1.551,"spectral_type":"A9V","color_index_bv":0.293,"luminosity_solar":6.415049325106628,"radial_velocity_km_s":21,"spectral_type_source":"SIMBAD (1995ApJS...99..135A, quality C)","surface_gravity_log_g":4.072,"surface_temperature_k":7255,"proper_motion_ra_mas_yr":-12.94,"proper_motion_dec_mas_yr":-3.1,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":5.9217},"designations":[{"catalog":"HD","designation":"HD 32115"},{"catalog":"HIP","designation":"HIP 23296"},{"catalog":"HR","designation":"HR 1613"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
