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-116429","name":"HD 116429","class":"k1_2iii_iv_orange_giant","category":"star","object_type":"K1/2III/IV orange giant","mag":6.44,"mag_band":"V","abs_mag":0.474,"abs_mag_band":"V","distance_ly":508.8241709335382,"distance_method":"parallax","ra_deg":200.98785,"dec_deg":-20.924587,"epoch_ra_deg":201.35171,"epoch_dec_deg":-21.065048,"epoch_moved_arcsec":1.13,"pm_ra_mas_yr":-37.39,"pm_dec_mas_yr":-19.9,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-116429","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"13240-2055","companions":[{"measured":2016,"magnitude":10.11,"components":null,"discoverer_code":"BU  610","separation_arcsec":4.3,"position_angle_deg":18}],"spectral_type":"K1/2III/IV","color_index_bv":1.101,"luminosity_solar":56.285949928272956,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1988MSS...C04....0H, quality E)","proper_motion_ra_mas_yr":-37.39,"proper_motion_dec_mas_yr":-19.9},"designations":[{"catalog":"HD","designation":"HD 116429"},{"catalog":"HIP","designation":"HIP 65381"}],"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.
