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-211076","name":"HD 211076","class":"k4iv_orange_subgiant","category":"star","object_type":"K4IV orange subgiant","mag":6.5,"mag_band":"V","abs_mag":0.402,"abs_mag_band":"V","distance_ly":540.8895828960044,"distance_method":"parallax","ra_deg":333.57667499999997,"dec_deg":17.189344,"epoch_ra_deg":333.899056,"epoch_dec_deg":17.321776,"epoch_moved_arcsec":3.289,"pm_ra_mas_yr":-82.75,"pm_dec_mas_yr":-91.39,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Pegasus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-211076","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"22143+1711","age_years":501464370,"companions":[{"measured":2024,"magnitude":9.23,"components":"AB","discoverer_code":"STF2877","separation_arcsec":24.5,"position_angle_deg":24},{"measured":2016,"magnitude":12.42,"components":"AC","discoverer_code":"STF2877","separation_arcsec":97.3,"position_angle_deg":44},{"measured":2016,"magnitude":11.31,"components":"AD","discoverer_code":"STF2877","separation_arcsec":101.2,"position_angle_deg":309}],"mass_solar":2.703,"radius_solar":13.528,"spectral_type":"K4IV","color_index_bv":1.288,"luminosity_solar":60.14506519775483,"radial_velocity_km_s":-105,"spectral_type_source":"SIMBAD (1985ApJS...59...95A, quality C)","surface_gravity_log_g":2.484,"surface_temperature_k":4629,"proper_motion_ra_mas_yr":-82.75,"proper_motion_dec_mas_yr":-91.39,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":75.2192},"designations":[{"catalog":"HD","designation":"HD 211076"},{"catalog":"HIP","designation":"HIP 109788"}],"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.
