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-126237","name":"HD 126237","class":"k2_orange_star","category":"star","object_type":"K2 orange star","mag":9.56,"mag_band":"V","abs_mag":5.455,"abs_mag_band":"V","distance_ly":215.99771345566876,"distance_method":"parallax","ra_deg":216.36201,"dec_deg":-40.043282,"epoch_ra_deg":216.778545,"epoch_dec_deg":-40.165722,"epoch_moved_arcsec":4.511,"pm_ra_mas_yr":-99.42,"pm_dec_mas_yr":-136.82,"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-126237","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"14254-4003","companions":[{"measured":2016,"magnitude":16.91,"components":null,"discoverer_code":"SKF1969","separation_arcsec":69.2,"position_angle_deg":132}],"radius_solar":1.158,"spectral_type":"K2","color_index_bv":0.926,"luminosity_solar":0.572796030985829,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1993yCat.3135....0C, quality E)","surface_gravity_log_g":4.347,"surface_temperature_k":4903,"proper_motion_ra_mas_yr":-99.42,"proper_motion_dec_mas_yr":-136.82,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.6935},"designations":[{"catalog":"HD","designation":"HD 126237"},{"catalog":"HIP","designation":"HIP 70512"}],"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.
