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-131119","name":"HD 131119","class":"k1v_orange_dwarf","category":"star","object_type":"K1V orange dwarf","mag":9.33,"mag_band":"V","abs_mag":5.588,"abs_mag_band":"V","distance_ly":182.72063054998486,"distance_method":"parallax","ra_deg":223.196925,"dec_deg":-33.614659,"epoch_ra_deg":223.609841,"epoch_dec_deg":-33.724913,"epoch_moved_arcsec":4.109,"pm_ra_mas_yr":153.98,"pm_dec_mas_yr":-3.39,"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-131119","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"14528-3337","companions":[{"measured":2016,"magnitude":11.44,"components":"AB","discoverer_code":"TOK 584","separation_arcsec":766.2,"position_angle_deg":33}],"spectral_type":"K1V","uncertainties":{"metallicity_fe_h":[0.1,0.1]},"color_index_bv":0.84,"luminosity_solar":0.5067572841772822,"metallicity_fe_h":-0.52,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (2006A&A...460..695T, quality C)","surface_gravity_log_g":4.72,"surface_temperature_k":5077,"metallicity_fe_h_source":"One spectroscopic determination, compiled from the literature (PASTEL, Soubiran+ 2016)","proper_motion_ra_mas_yr":153.98,"proper_motion_dec_mas_yr":-3.39,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"HD","designation":"HD 131119"},{"catalog":"HIP","designation":"HIP 72797"}],"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.
