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-217379","name":"HD 217379","class":"k6_5vke_orange_dwarf","category":"star","object_type":"K6.5Vke orange dwarf","mag":9.57,"mag_band":"V","abs_mag":7.145,"abs_mag_band":"V","distance_ly":99.62022554066897,"distance_method":"parallax","ra_deg":345.116445,"dec_deg":-26.311889,"epoch_ra_deg":345.481406,"epoch_dec_deg":-26.169006,"epoch_moved_arcsec":5.283,"pm_ra_mas_yr":113.63,"pm_dec_mas_yr":-162.16,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Piscis Austrinus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-217379","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"23005-2619","companions":[{"measured":2018,"magnitude":10.76,"components":"AB","discoverer_code":"RST1154","separation_arcsec":2.4,"position_angle_deg":239},{"measured":2000,"magnitude":7.56,"components":"AC","discoverer_code":"SHY 364","separation_arcsec":581.2,"position_angle_deg":349}],"spectral_type":"K6.5Vke","color_index_bv":1.344,"luminosity_solar":0.120781383510678,"radial_velocity_km_s":14,"spectral_type_source":"SIMBAD (2006AJ....132..161G, quality C)","proper_motion_ra_mas_yr":113.63,"proper_motion_dec_mas_yr":-162.16},"designations":[{"catalog":"HD","designation":"HD 217379"},{"catalog":"HIP","designation":"HIP 113597"}],"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.
