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-202214","name":"HD 202214","class":"o9_5iv_blue_subgiant","category":"star","object_type":"O9.5IV blue subgiant","mag":5.64,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":317.950995,"dec_deg":59.98661,"epoch_ra_deg":318.118697,"epoch_dec_deg":60.096256,"epoch_moved_arcsec":0.123,"pm_ra_mas_yr":-2.9,"pm_dec_mas_yr":-3.58,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Cepheus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-202214","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"21118+5959","companions":[{"measured":2019,"magnitude":6.77,"components":"AB","discoverer_code":"STF2780","separation_arcsec":1,"position_angle_deg":211},{"measured":2017,"magnitude":10.3,"components":"AB,E","discoverer_code":"WAL 137","separation_arcsec":61.5,"position_angle_deg":46},{"measured":2003,"magnitude":14.2,"components":"AB,D","discoverer_code":"WAL 137","separation_arcsec":96.3,"position_angle_deg":260},{"measured":2017,"magnitude":8.9,"components":"AC","discoverer_code":"STF2780","separation_arcsec":118.8,"position_angle_deg":211}],"spectral_type":"O9.5IV","color_index_bv":0.11,"radial_velocity_km_s":-16,"spectral_type_source":"SIMBAD (2014ApJS..211...10S, quality C)","proper_motion_ra_mas_yr":-2.9,"proper_motion_dec_mas_yr":-3.58},"designations":[{"catalog":"HD","designation":"HD 202214"},{"catalog":"HIP","designation":"HIP 104642"},{"catalog":"HR","designation":"HR 8119"}],"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.
