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-1-b","name":"CoRoT-1 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":2569.815454104216,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":102.0798591,"dec_deg":-3.1021394,"epoch_ra_deg":102.415942,"epoch_dec_deg":-3.131613,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"CoRoT-1","semi_major_axis_km":4116933.4016639995,"periapsis_km":null,"mass_kg":1.954989151521508e+27,"mass_msun":0.000983192,"constellation":"Monoceros","discovered":"2008","featured":false,"url":"https://spacecatalog.org/object/corot-1-b","radius_km":106514.27,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"CoRoT-1","host_v_mag":13.623,"eccentricity":0,"uncertainties":{"mass_kg":[2.277784824775632e+26,2.277784824775632e+26],"radius_km":[5740.290000000001,5740.290000000001],"distance_ly":[76.61739468944019,76.61739468944019],"host_mass_solar":[0.15,0.15],"inclination_deg":[0.5,0.5],"host_radius_solar":[0.05,0.05],"host_temperature_k":[150,150],"semi_major_axis_km":[34407.510260999996,32911.531554],"orbital_period_days":[0.0000064,0.0000064]},"host_mass_solar":0.95,"inclination_deg":85.1,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.11,"planets_in_system":1,"discovery_facility":"CoRoT","host_spectral_type":"G0 V","host_temperature_k":5950,"orbital_period_days":1.5089557,"transit_midpoint_bjd":2454159.4532,"equilibrium_temperature_k":1898},"designations":[{"catalog":"Exoplanet","designation":"CoRoT-1 b"},{"catalog":"Host star","designation":"CoRoT-1"}],"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.
