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-19-b","name":"CoRoT-19 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":2578.797800746535,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":97.0335983,"dec_deg":-0.1707293,"epoch_ra_deg":97.377368,"epoch_dec_deg":-0.187211,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"CoRoT-19","semi_major_axis_km":7749169.702259999,"periapsis_km":null,"mass_kg":2.1068613803994426e+27,"mass_msun":0.00105957,"constellation":"Monoceros","discovered":"2011","featured":false,"url":"https://spacecatalog.org/object/corot-19-b","radius_km":92227.32600000002,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"CoRoT-19","host_v_mag":14.135,"eccentricity":0.047,"uncertainties":{"mass_kg":[1.138892412387816e+26,1.138892412387816e+26],"radius_km":[2168.554,2168.554],"distance_ly":[81.77066545736474,87.20443071012568],"eccentricity":[0.045,0.045],"host_mass_solar":[0.05,0.05],"inclination_deg":[0.7,0.7],"host_radius_solar":[0.04,0.04],"host_temperature_k":[70,70],"semi_major_axis_km":[119678.29656,119678.29656],"orbital_period_days":[0.00002,0.00002]},"host_mass_solar":1.21,"inclination_deg":88,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.65,"planets_in_system":1,"discovery_facility":"CoRoT","host_spectral_type":"F9 V","host_temperature_k":6090,"orbital_period_days":3.89713,"transit_midpoint_bjd":2455257.44102,"equilibrium_temperature_k":2000},"designations":[{"catalog":"Exoplanet","designation":"CoRoT-19 b"},{"catalog":"Host star","designation":"CoRoT-19"}],"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.
