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-126595","name":"HD 126595","class":"g6ii_yellow_bright_giant","category":"star","object_type":"G6II yellow bright giant","mag":6.93,"mag_band":"V","abs_mag":-0.803,"abs_mag_band":"V","distance_ly":1148.4380278006236,"distance_method":"parallax","ra_deg":217.958805,"dec_deg":-76.273962,"epoch_ra_deg":218.676626,"epoch_dec_deg":-76.392734,"epoch_moved_arcsec":0.205,"pm_ra_mas_yr":-5.04,"pm_dec_mas_yr":-5.79,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Apus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-126595","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"14318-7616","companions":[{"measured":2016,"magnitude":9.96,"components":"AB","discoverer_code":"I   326","separation_arcsec":2.3,"position_angle_deg":118},{"measured":2015,"magnitude":13.13,"components":"AC","discoverer_code":"I   326","separation_arcsec":14.7,"position_angle_deg":10}],"spectral_type":"G6II","color_index_bv":1.028,"luminosity_solar":182.4735830762581,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1975MSS...C01....0H, quality C)","proper_motion_ra_mas_yr":-5.04,"proper_motion_dec_mas_yr":-5.79},"designations":[{"catalog":"HD","designation":"HD 126595"},{"catalog":"HIP","designation":"HIP 71055"}],"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.
