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":"aiolos","name":"Aiolos","class":"a8iii_white_giant","category":"star","object_type":"A8III white giant","mag":7.36,"mag_band":"V","abs_mag":2.579,"abs_mag_band":"V","distance_ly":294.897224319993,"distance_method":"parallax","ra_deg":164.262765,"dec_deg":-68.667347,"epoch_ra_deg":164.496699,"epoch_dec_deg":-68.810558,"epoch_moved_arcsec":1.165,"pm_ra_mas_yr":-41.69,"pm_dec_mas_yr":13.03,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Carina","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/aiolos","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"10571-6840","age_years":504595340,"companions":[{"measured":2013,"magnitude":16.5,"components":"AB","discoverer_code":"RMU   1","separation_arcsec":0.6,"position_angle_deg":151},{"measured":2013,"magnitude":12.67,"components":"AC","discoverer_code":"KOU   2","separation_arcsec":4.5,"position_angle_deg":320}],"mass_solar":1.579,"wikidata_id":"Q31888566","radius_solar":1.51,"spectral_type":"A8III","color_index_bv":0.23,"luminosity_solar":8.098414473257884,"wikipedia_article":"HD 95086","radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1975MSS...C01....0H, quality C)","surface_gravity_log_g":4.182,"surface_temperature_k":7569,"proper_motion_ra_mas_yr":-41.69,"proper_motion_dec_mas_yr":13.03,"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":6.8534},"designations":[{"catalog":"Common name","designation":"Aiolos"},{"catalog":"HD","designation":"HD 95086"},{"catalog":"HIP","designation":"HIP 53524"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
