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-124314","name":"HD 124314","class":"o6v_n_f_blue_main_sequence_star","category":"star","object_type":"O6V(n)((f)) blue main-sequence star","mag":6.68,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":213.75670499999998,"dec_deg":-61.706775,"epoch_ra_deg":214.253054,"epoch_dec_deg":-61.832049,"epoch_moved_arcsec":0.146,"pm_ra_mas_yr":-4.6,"pm_dec_mas_yr":-2.95,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Centaurus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-124314","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"14150-6142","companions":[{"measured":2015,"magnitude":17.5,"components":"Aa,Ac","discoverer_code":"VSP  62","separation_arcsec":1,"position_angle_deg":306},{"measured":2015,"magnitude":13.13,"components":"AC","discoverer_code":"SNA  37","separation_arcsec":2.4,"position_angle_deg":44},{"measured":2020,"magnitude":8.66,"components":"AB","discoverer_code":"COO 167","separation_arcsec":2.8,"position_angle_deg":157}],"radius_solar":34.547,"spectral_type":"O6V(n)((f))","color_index_bv":0.233,"radial_velocity_km_s":-17,"spectral_type_source":"SIMBAD (1973AJ.....78.1067W, quality C)","surface_gravity_log_g":2.602,"surface_temperature_k":17043,"proper_motion_ra_mas_yr":-4.6,"proper_motion_dec_mas_yr":-2.95,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: above 7,500 K GSP-Phot's temperature and extinction are degenerate"},"designations":[{"catalog":"HD","designation":"HD 124314"},{"catalog":"HIP","designation":"HIP 69628"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
