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-60033","name":"HIP 60033","class":"f8v_yellow_white_main_sequence_star","category":"star","object_type":"F8V yellow-white main-sequence star","mag":9.25,"mag_band":"V","abs_mag":3.26,"abs_mag_band":"V","distance_ly":514.4422145397091,"distance_method":"parallax","ra_deg":184.67542500000002,"dec_deg":21.513607,"epoch_ra_deg":185.014864,"epoch_dec_deg":21.364686,"epoch_moved_arcsec":1.668,"pm_ra_mas_yr":-57.31,"pm_dec_mas_yr":25.12,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Coma Berenices","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-60033","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":2382277000,"mass_solar":1.539,"radius_solar":2.521,"spectral_type":"F8V","color_index_bv":0.526,"luminosity_solar":4.325138310350087,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality C)","surface_gravity_log_g":3.857,"surface_temperature_k":6156,"proper_motion_ra_mas_yr":-57.31,"proper_motion_dec_mas_yr":25.12,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: Gaia's classifier calls the source a binary, which GSP-Phot fitted as one star","bolometric_luminosity_solar":8.2344},"designations":[{"catalog":"HIP","designation":"HIP 60033"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
