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-114792","name":"HD 114792","class":"f5_6ib_yellow_white_supergiant","category":"star","object_type":"F5/6Ib yellow-white supergiant","mag":6.82,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":198.507975,"dec_deg":-62.653889,"epoch_ra_deg":198.940642,"epoch_dec_deg":-62.796204,"epoch_moved_arcsec":0.169,"pm_ra_mas_yr":-5.47,"pm_dec_mas_yr":-3.23,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Centaurus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-114792","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"13140-6239","companions":[{"measured":2015,"magnitude":10.52,"components":"AB","discoverer_code":"I   399","separation_arcsec":8.3,"position_angle_deg":137},{"measured":2015,"magnitude":11.75,"components":"AC","discoverer_code":"I   399","separation_arcsec":35.6,"position_angle_deg":187}],"radius_solar":107.387,"spectral_type":"F5/6Ib","color_index_bv":0.998,"radial_velocity_km_s":-18.6,"spectral_type_source":"SIMBAD (1975MSS...C01....0H, quality D)","surface_gravity_log_g":1.33,"surface_temperature_k":6292,"proper_motion_ra_mas_yr":-5.47,"proper_motion_dec_mas_yr":-3.23,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)"},"designations":[{"catalog":"HD","designation":"HD 114792"},{"catalog":"HIP","designation":"HIP 64564"}],"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.
