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":"hip-44033","name":"HIP 44033","class":"yellow_white_star","category":"star","object_type":"Yellow-white star","mag":11.94,"mag_band":"V","abs_mag":4.934,"abs_mag_band":"V","distance_ly":821.5526905796833,"distance_method":"parallax","ra_deg":134.496855,"dec_deg":24.472929,"epoch_ra_deg":134.891679,"epoch_dec_deg":24.367617,"epoch_moved_arcsec":8.441,"pm_ra_mas_yr":207.63,"pm_dec_mas_yr":-238.77,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Cancer","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-44033","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"08580+2428","companions":[{"measured":1994,"magnitude":19.66,"components":"AC","discoverer_code":"OSO  23","separation_arcsec":19.4,"position_angle_deg":283},{"measured":2015,"magnitude":18,"components":"AB","discoverer_code":"OSO  23","separation_arcsec":25.4,"position_angle_deg":341}],"radius_solar":0.774,"color_index_bv":0.584,"luminosity_solar":0.9255502447634352,"variable_mag_max":11.835,"variable_mag_min":12.055,"radial_velocity_km_s":0,"surface_gravity_log_g":4.51,"surface_temperature_k":5926,"proper_motion_ra_mas_yr":207.63,"proper_motion_dec_mas_yr":-238.77,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.7497},"designations":[{"catalog":"HIP","designation":"HIP 44033"}],"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.
