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-114886","name":"HD 114886","class":"o9_b0v_blue_main_sequence_star","category":"star","object_type":"O9-B0V blue main-sequence star","mag":6.87,"mag_band":"V","abs_mag":-1.488,"abs_mag_band":"V","distance_ly":1531.250703734165,"distance_method":"parallax","ra_deg":198.68496,"dec_deg":-63.581056,"epoch_ra_deg":199.122497,"epoch_dec_deg":-63.723279,"epoch_moved_arcsec":0.138,"pm_ra_mas_yr":-5.16,"pm_dec_mas_yr":-0.49,"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-114886","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"13147-6335","companions":[{"measured":2019,"magnitude":8.7,"components":"Aa,Ab","discoverer_code":"WSI  58","separation_arcsec":0.2,"position_angle_deg":282},{"measured":2019,"magnitude":9.13,"components":"AB","discoverer_code":"MLO   3","separation_arcsec":1.7,"position_angle_deg":39},{"measured":2015,"magnitude":12.64,"components":"AC","discoverer_code":"SNA  32","separation_arcsec":3.6,"position_angle_deg":92},{"measured":2012,"magnitude":13.94,"components":"AD","discoverer_code":"SNA  32","separation_arcsec":3.6,"position_angle_deg":10},{"measured":2015,"magnitude":11.73,"components":"AE","discoverer_code":"SNA  32","separation_arcsec":5.2,"position_angle_deg":143},{"measured":2012,"magnitude":11.83,"components":"AF","discoverer_code":"SNA  32","separation_arcsec":5.3,"position_angle_deg":138}],"spectral_type":"O9-B0V","color_index_bv":0.112,"luminosity_solar":342.9256732975598,"radial_velocity_km_s":-19,"spectral_type_source":"SIMBAD (2019AJ....158...46B, quality C)","proper_motion_ra_mas_yr":-5.16,"proper_motion_dec_mas_yr":-0.49},"designations":[{"catalog":"HD","designation":"HD 114886"},{"catalog":"HIP","designation":"HIP 64624"}],"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.
