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-110067","name":"HD 110067","class":"k0_0_v_orange_star","category":"star","object_type":"K0.0 V orange star","mag":8.419,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":104.88699872803892,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":189.8392243,"dec_deg":20.0273377,"epoch_ra_deg":190.174919,"epoch_dec_deg":19.879611,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"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/hd-110067","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12396+1956","companions":[{"measured":2015,"magnitude":8.9,"components":"AB","discoverer_code":"BGH  40","separation_arcsec":415.6,"position_angle_deg":148}],"mass_solar":0.798,"radius_solar":0.788,"spectral_type":"K0.0 V","stars_in_system":3,"planets_in_system":6,"surface_temperature_k":5266,"stellar_parameters_method":"NASA Exoplanet Archive composite parameters"},"designations":[],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
