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-95429","name":"HD 95429","class":"a3iii_iv_white_giant","category":"star","object_type":"A3III/IV white giant","mag":6.15,"mag_band":"V","abs_mag":2.22,"abs_mag_band":"V","distance_ly":199.24045108133794,"distance_method":"parallax","ra_deg":165.03459,"dec_deg":-51.8178,"epoch_ra_deg":165.326231,"epoch_dec_deg":-51.961683,"epoch_moved_arcsec":1.708,"pm_ra_mas_yr":-64,"pm_dec_mas_yr":2.81,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Vela","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-95429","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"11001-5149","age_years":434440850,"companions":[{"measured":2012,"magnitude":20,"components":"AC","discoverer_code":"VIG  13","separation_arcsec":5.7,"position_angle_deg":268},{"measured":2012,"magnitude":18,"components":"AD","discoverer_code":"VIG  13","separation_arcsec":6.1,"position_angle_deg":252},{"measured":2012,"magnitude":19,"components":"AE","discoverer_code":"VIG  13","separation_arcsec":8.5,"position_angle_deg":145},{"measured":2016,"magnitude":13.4,"components":"AB","discoverer_code":"RST1550","separation_arcsec":10.2,"position_angle_deg":261}],"mass_solar":1.695,"radius_solar":1.566,"spectral_type":"A3III/IV","color_index_bv":0.188,"luminosity_solar":11.2719745617551,"radial_velocity_km_s":14,"spectral_type_source":"SIMBAD (1978MSS...C02....0H, quality D)","surface_gravity_log_g":4.277,"surface_temperature_k":8014,"proper_motion_ra_mas_yr":-64,"proper_motion_dec_mas_yr":2.81,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: above 7,500 K GSP-Phot's temperature and extinction are degenerate","bolometric_luminosity_solar":9.2354},"designations":[{"catalog":"HD","designation":"HD 95429"},{"catalog":"HIP","designation":"HIP 53771"},{"catalog":"HR","designation":"HR 4296"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
