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-219832","name":"95 ψ³ Aqr","class":"b9v_blue_white_main_sequence_star","category":"star","object_type":"B9V blue-white main-sequence star","mag":4.99,"mag_band":"V","abs_mag":0.469,"abs_mag_band":"V","distance_ly":261.5529532004995,"distance_method":"parallax","ra_deg":349.740315,"dec_deg":-9.61075,"epoch_ra_deg":350.089505,"epoch_dec_deg":-9.464013,"epoch_moved_arcsec":1.178,"pm_ra_mas_yr":43.47,"pm_dec_mas_yr":-7.8,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Aquarius","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-219832","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"23190-0937","companions":[{"measured":2022,"magnitude":9,"components":"AB","discoverer_code":"HO  199","separation_arcsec":1.5,"position_angle_deg":131},{"measured":1959,"magnitude":13.1,"components":"AC","discoverer_code":"HO  199","separation_arcsec":131.2,"position_angle_deg":231}],"spectral_type":"B9V","color_index_bv":-0.022,"luminosity_solar":56.545754068762086,"radial_velocity_km_s":-10,"spectral_type_source":"SIMBAD (1999MSS...C05....0H, quality C)","surface_temperature_k":10032,"proper_motion_ra_mas_yr":43.47,"proper_motion_dec_mas_yr":-7.8,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"Bayer/Flamsteed","designation":"95 Psi3 Aqr"},{"catalog":"HD","designation":"HD 219832"},{"catalog":"HIP","designation":"HIP 115115"},{"catalog":"HR","designation":"HR 8865"}],"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.
