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-5-b","name":"CoRoT-5 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":2878.2387095645,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":101.2772396,"dec_deg":0.8152163,"epoch_ra_deg":101.623333,"epoch_dec_deg":0.787794,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"CoRoT-5","semi_major_axis_km":7400606.663528999,"periapsis_km":null,"mass_kg":8.863891549375964e+26,"mass_msun":0.000445778,"constellation":"Monoceros","discovered":"2009","featured":false,"url":"https://spacecatalog.org/object/corot-5-b","radius_km":99230.4798,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"CoRoT-5","host_v_mag":14.043,"eccentricity":0.09,"uncertainties":{"mass_kg":[4.5555696495512645e+25,8.920627144119983e+25],"radius_km":[3361.2587000000003,3291.0996000000005],"distance_ly":[83.56126397102966,83.56126397102966],"eccentricity":[0.04,0.09],"host_mass_solar":[0.02,0.02],"inclination_deg":[1.38,0.99],"host_radius_solar":[0.04,0.04],"host_temperature_k":[65,65],"semi_major_axis_km":[43383.38250299999,38895.446381999995],"orbital_period_days":[0.0000019,0.0000019],"argument_of_periastron_deg":[48.13,289.34]},"host_mass_solar":1,"inclination_deg":85.83,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.186,"planets_in_system":1,"discovery_facility":"CoRoT","host_spectral_type":"F9 V","host_temperature_k":6100,"orbital_period_days":4.0378962,"transit_midpoint_bjd":2454400.19885,"equilibrium_temperature_k":1438,"argument_of_periastron_deg":-128.34},"designations":[{"catalog":"Exoplanet","designation":"CoRoT-5 b"},{"catalog":"Host star","designation":"CoRoT-5"}],"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.
