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-13460","name":"HD 13460","class":"g1_2v_yellow_main_sequence_star","category":"star","object_type":"G1/2V yellow main-sequence star","mag":8.5,"mag_band":"V","abs_mag":3.788,"abs_mag_band":"V","distance_ly":285.6011152423104,"distance_method":"parallax","ra_deg":32.7483,"dec_deg":-25.457827,"epoch_ra_deg":33.055346,"epoch_dec_deg":-25.331671,"epoch_moved_arcsec":2.965,"pm_ra_mas_yr":74.83,"pm_dec_mas_yr":-82.18,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Fornax","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-13460","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"02110-2527","age_years":7279153000,"companions":[{"measured":2016,"magnitude":14.3,"components":null,"discoverer_code":"B    28","separation_arcsec":2.8,"position_angle_deg":318}],"mass_solar":1.084,"radius_solar":1.492,"spectral_type":"G1/2V","color_index_bv":0.577,"luminosity_solar":2.659500032721517,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1988MSS...C04....0H, quality D)","surface_gravity_log_g":4.179,"surface_temperature_k":5922,"proper_motion_ra_mas_yr":74.83,"proper_motion_dec_mas_yr":-82.18,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: Gaia's classifier calls the source a binary, which GSP-Phot fitted as one star","bolometric_luminosity_solar":2.463},"designations":[{"catalog":"HD","designation":"HD 13460"},{"catalog":"HIP","designation":"HIP 10190"}],"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.
