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-14055","name":"HIP 14055","class":"m0_red_star","category":"star","object_type":"M0 red star","mag":8.69,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":45.266025,"dec_deg":-41.35152,"epoch_ra_deg":45.518096,"epoch_dec_deg":-41.244922,"epoch_moved_arcsec":0.439,"pm_ra_mas_yr":16.47,"pm_dec_mas_yr":0.54,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Eridanus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-14055","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"mass_solar":7.626,"radius_solar":54.546,"spectral_type":"M0","color_index_bv":1.697,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality D)","surface_gravity_log_g":1.662,"surface_temperature_k":4918,"proper_motion_ra_mas_yr":16.47,"proper_motion_dec_mas_yr":0.54,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":1749.0137},"designations":[{"catalog":"HIP","designation":"HIP 14055"}],"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.
