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":"ogle-tr-113-b","name":"OGLE-TR-113 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1847.5421556504875,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":163.1010355,"dec_deg":-61.4468591,"epoch_ra_deg":163.361553,"epoch_dec_deg":-61.589336,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"OGLE-TR-113","semi_major_axis_km":3424295.2603229997,"periapsis_km":null,"mass_kg":2.3915486504891902e+27,"mass_msun":0.00120274,"constellation":"Carina","discovered":"2004","featured":false,"url":"https://spacecatalog.org/object/ogle-tr-113-b","radius_km":78138.10310000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"OGLE-TR-113","host_v_mag":15.8485,"eccentricity":0,"uncertainties":{"mass_kg":[3.0369070824505943e+26,3.0369070824505943e+26],"radius_km":[1358.5353,2002.7234],"distance_ly":[36.04027973770015,37.47210623587665],"host_mass_solar":[0.015,0.017],"inclination_deg":[0.62,1.6],"host_radius_solar":[0.011,0.02],"host_temperature_k":[75,75],"semi_major_axis_km":[22439.680604999998,23935.659312]},"host_mass_solar":0.779,"inclination_deg":87.8,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.774,"planets_in_system":1,"discovery_facility":"OGLE","host_spectral_type":"K4 V","host_temperature_k":4790,"orbital_period_days":1.4324752,"transit_midpoint_bjd":2454819.73853,"equilibrium_temperature_k":1342},"designations":[{"catalog":"Exoplanet","designation":"OGLE-TR-113 b"},{"catalog":"Host star","designation":"OGLE-TR-113"}],"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.
