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-b","name":"CoRoT-24 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"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":102.257227,"epoch_dec_deg":-3.748367,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"CoRoT-24","semi_major_axis_km":8377480.759199999,"periapsis_km":null,"mass_kg":3.4041356846410864e+25,"mass_msun":0.0000171199,"constellation":"Monoceros","discovered":"2014","featured":false,"url":"https://spacecatalog.org/object/corot-24-b","radius_km":23598.97,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"CoRoT-24","host_v_mag":15.383,"eccentricity":0,"uncertainties":{"radius_km":[2551.2400000000002,2551.2400000000002],"distance_ly":[49.680139453814355,52.325267677097145],"host_mass_solar":[0.09,0.09],"inclination_deg":[2,2],"host_radius_solar":[0.09,0.09],"host_temperature_k":[150,150],"semi_major_axis_km":[299195.7414,299195.7414],"orbital_period_days":[0.0006,0.0006]},"host_mass_solar":0.91,"inclination_deg":86.5,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.86,"planets_in_system":2,"discovery_facility":"CoRoT","host_spectral_type":"K1 V","host_temperature_k":4950,"orbital_period_days":5.1134,"transit_midpoint_bjd":2454789.611,"equilibrium_temperature_k":1070},"designations":[{"catalog":"Exoplanet","designation":"CoRoT-24 b"},{"catalog":"Host star","designation":"CoRoT-24"}],"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.
