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-32040","name":"HD 32040","class":"b9v_blue_white_main_sequence_star","category":"star","object_type":"B9V blue-white main-sequence star","mag":6.65,"mag_band":"V","abs_mag":3.983,"abs_mag_band":"V","distance_ly":111.39218768159938,"distance_method":"parallax","ra_deg":75.14139,"dec_deg":3.615749,"epoch_ra_deg":75.494602,"epoch_dec_deg":3.655667,"epoch_moved_arcsec":0.781,"pm_ra_mas_yr":10.35,"pm_dec_mas_yr":-27.39,"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-32040","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"05006+0337","companions":[{"measured":2020,"magnitude":6.95,"components":"AB","discoverer_code":"STF 627","separation_arcsec":21.2,"position_angle_deg":260},{"measured":2016,"magnitude":11.83,"components":"AC","discoverer_code":"SLE1022","separation_arcsec":243.4,"position_angle_deg":238}],"spectral_type":"B9V","color_index_bv":-0.053,"luminosity_solar":2.222286254328203,"variable_mag_max":6.376,"variable_mag_min":6.826,"radial_velocity_km_s":42,"spectral_type_source":"SIMBAD (1999MSS...C05....0H, quality C)","surface_temperature_k":11695,"proper_motion_ra_mas_yr":10.35,"proper_motion_dec_mas_yr":-27.39,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"HD","designation":"HD 32040"},{"catalog":"HIP","designation":"HIP 23287"},{"catalog":"HR","designation":"HR 1610"}],"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.
