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-36-b","name":"CoRoT-36 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":3020.071071978403,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":277.7510149,"dec_deg":7.1833465,"epoch_ra_deg":278.076457,"epoch_dec_deg":7.201669,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"CoRoT-36","semi_major_axis_km":9873459.4662,"periapsis_km":null,"mass_kg":1.29072472783457e+27,"mass_msun":0.000649124,"constellation":"Ophiuchus","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/corot-36-b","radius_km":100803.719740899,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"CoRoT-36","host_v_mag":13.126,"eccentricity":0,"uncertainties":{"mass_kg":[8.161935778953899e+26,8.921185618856587e+26],"radius_km":[10008.879985130001,10008.879985130001],"distance_ly":[85.60626445931365,90.65842675014599],"host_mass_solar":[0.09,0.09],"inclination_deg":[0.26,0.26],"host_radius_solar":[0.1,0.2],"host_temperature_k":[140,140],"semi_major_axis_km":[1047185.0948999999,1047185.0948999999],"orbital_period_days":[0.000023,0.000023]},"host_mass_solar":1.32,"inclination_deg":85.83,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.52,"planets_in_system":1,"discovery_facility":"CoRoT","host_spectral_type":"F3 V","host_temperature_k":6730,"orbital_period_days":5.616531,"transit_midpoint_bjd":2455662.52236,"equilibrium_temperature_k":1567},"designations":[{"catalog":"Exoplanet","designation":"CoRoT-36 b"},{"catalog":"Host star","designation":"CoRoT-36"}],"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.
