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-10-b","name":"CoRoT-10 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1103.6675203005796,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":291.0636813,"dec_deg":0.7460143,"epoch_ra_deg":291.406073,"epoch_dec_deg":0.798043,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"CoRoT-10","semi_major_axis_km":15782575.358849999,"periapsis_km":null,"mass_kg":5.219674716449665e+27,"mass_msun":0.00262505,"constellation":"Aquila","discovered":"2010","featured":false,"url":"https://spacecatalog.org/object/corot-10-b","radius_km":69329.947,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"CoRoT-10","host_v_mag":15.293,"eccentricity":0.53,"uncertainties":{"mass_kg":[3.0368473607719165e+26,3.0368473607719165e+26],"radius_km":[4974.918000000001,4974.918000000001],"distance_ly":[13.002223997677977,13.002223997677977],"eccentricity":[0.04,0.04],"host_mass_solar":[0.05,0.05],"inclination_deg":[0.2,0.2],"host_radius_solar":[0.05,0.05],"host_temperature_k":[75,75],"semi_major_axis_km":[314155.52846999996,314155.52846999996],"orbital_period_days":[0.0002,0.0002],"argument_of_periastron_deg":[6.4,6.4]},"host_mass_solar":0.89,"inclination_deg":88.55,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.79,"planets_in_system":1,"discovery_facility":"CoRoT","host_spectral_type":"K1 V","host_temperature_k":5075,"orbital_period_days":13.2406,"periastron_epoch_bjd":2454990.85,"transit_midpoint_bjd":2454273.3436,"equilibrium_temperature_k":600,"argument_of_periastron_deg":218.9},"designations":[{"catalog":"Exoplanet","designation":"CoRoT-10 b"},{"catalog":"Host star","designation":"CoRoT-10"}],"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.
