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":"corot-24","name":"CoRoT-24","class":"k1_v_orange_star","category":"star","object_type":"K1 V orange star","mag":15.383,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":1929.3943602022814,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":101.922543,"dec_deg":-3.7192892,"epoch_ra_deg":102.256977,"epoch_dec_deg":-3.748338,"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":"Monoceros","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/corot-24","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"06477-0343","companions":[{"measured":2016,"magnitude":20.5,"components":"AB","discoverer_code":"CRT  24","separation_arcsec":8.3,"position_angle_deg":59},{"measured":2016,"magnitude":20.5,"components":"AC","discoverer_code":"CRT  24","separation_arcsec":8.7,"position_angle_deg":285},{"measured":2016,"magnitude":20.8,"components":"AD","discoverer_code":"CRT  24","separation_arcsec":8.7,"position_angle_deg":24},{"measured":2016,"magnitude":20.5,"components":"AE","discoverer_code":"CRT  24","separation_arcsec":11.4,"position_angle_deg":235},{"measured":2016,"magnitude":20.1,"components":"AF","discoverer_code":"CRT  24","separation_arcsec":12.5,"position_angle_deg":108},{"measured":2016,"magnitude":20.4,"components":"AG","discoverer_code":"CRT  24","separation_arcsec":18.4,"position_angle_deg":329},{"measured":2016,"magnitude":19.4,"components":"AH","discoverer_code":"CRT  24","separation_arcsec":19.2,"position_angle_deg":127},{"measured":2016,"magnitude":20.1,"components":"AI","discoverer_code":"CRT  24","separation_arcsec":19.9,"position_angle_deg":357},{"measured":2016,"magnitude":20.4,"components":"AJ","discoverer_code":"CRT  24","separation_arcsec":26,"position_angle_deg":52}],"mass_solar":0.91,"radius_solar":0.86,"spectral_type":"K1 V","stars_in_system":1,"planets_in_system":2,"surface_temperature_k":4950,"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
