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-127167","name":"HD 127167","class":"a5iv_v_white_subgiant","category":"star","object_type":"A5IV/V white subgiant","mag":5.96,"mag_band":"V","abs_mag":1.464,"abs_mag_band":"V","distance_ly":258.6488568133096,"distance_method":"parallax","ra_deg":217.46049,"dec_deg":0.828929,"epoch_ra_deg":217.803353,"epoch_dec_deg":0.709216,"epoch_moved_arcsec":0.461,"pm_ra_mas_yr":15.7,"pm_dec_mas_yr":7.26,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-127167","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"14298+0050","age_years":823243600,"companions":[{"measured":2020,"magnitude":9.25,"components":null,"discoverer_code":"SKF 911","separation_arcsec":135.4,"position_angle_deg":331}],"mass_solar":1.914,"radius_solar":2.243,"spectral_type":"A5IV/V","color_index_bv":0.159,"luminosity_solar":22.615177461083626,"radial_velocity_km_s":-9,"spectral_type_source":"SIMBAD (1999MSS...C05....0H, quality D)","surface_gravity_log_g":3.922,"surface_temperature_k":8026,"proper_motion_ra_mas_yr":15.7,"proper_motion_dec_mas_yr":7.26,"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":18.3642},"designations":[{"catalog":"HD","designation":"HD 127167"},{"catalog":"HIP","designation":"HIP 70894"},{"catalog":"HR","designation":"HR 5418"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
