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-110762","name":"HD 110762","class":"k2iii_orange_giant","category":"star","object_type":"K2III orange giant","mag":7.88,"mag_band":"V","abs_mag":0.819,"abs_mag_band":"V","distance_ly":842.7812307361329,"distance_method":"parallax","ra_deg":190.905,"dec_deg":58.869667,"epoch_ra_deg":191.204478,"epoch_dec_deg":58.722347,"epoch_moved_arcsec":1.889,"pm_ra_mas_yr":-66.8,"pm_dec_mas_yr":-23.5,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Ursa Major","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-110762","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12436+5852","age_years":413495270,"companions":[{"measured":1852,"magnitude":null,"components":null,"discoverer_code":"STT 254","separation_arcsec":0.3,"position_angle_deg":189}],"mass_solar":2.902,"radius_solar":11.123,"spectral_type":"K2III","color_index_bv":1.183,"luminosity_solar":40.96377763696797,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality C)","surface_gravity_log_g":2.525,"surface_temperature_k":4641,"proper_motion_ra_mas_yr":-66.8,"proper_motion_dec_mas_yr":-23.5,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":48.3895},"designations":[{"catalog":"HD","designation":"HD 110762"},{"catalog":"HIP","designation":"HIP 62101"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T18:38:07.546Z","attribution":"Data from SpaceCatalog.org.
