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":"kepler-113-b","name":"Kepler-113 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":855.6745185036535,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":287.9978721,"dec_deg":50.9441847,"epoch_ra_deg":288.165787,"epoch_dec_deg":50.988411,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-113","semi_major_axis_km":7663898.915960999,"periapsis_km":null,"mass_kg":6.9874364053159135e+25,"mass_msun":0.0000351408,"constellation":"Cygnus","discovered":"2014","featured":false,"url":"https://spacecatalog.org/object/kepler-113-b","radius_km":11608.142000000002,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-113","host_v_mag":13.655,"eccentricity":0,"uncertainties":{"mass_kg":[2.5083105044723793e+25,2.5083105044723793e+25],"radius_km":[318.90500000000003,318.90500000000003],"distance_ly":[3.6105511013243494,3.643166739096024],"host_mass_solar":[0.06,0.06],"host_radius_solar":[0.02,0.02],"host_temperature_k":[74,74],"semi_major_axis_km":[76294.914057,76294.914057]},"host_mass_solar":0.75,"inclination_deg":86.54,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.69,"planets_in_system":2,"discovery_facility":"Kepler","host_temperature_k":4725,"orbital_period_days":4.754,"transit_midpoint_bjd":2454961.5463,"equilibrium_temperature_k":775},"designations":[{"catalog":"Exoplanet","designation":"Kepler-113 b"},{"catalog":"Host star","designation":"Kepler-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.
