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-1115-b","name":"Kepler-1115 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":3206.9162760809936,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":294.9917723,"dec_deg":40.1443964,"epoch_ra_deg":295.220829,"epoch_dec_deg":40.205779,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-1115","semi_major_axis_km":31924185.60738,"periapsis_km":null,"mass_kg":2.1081752573303568e+25,"mass_msun":0.0000106023,"constellation":"Cygnus","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kepler-1115-b","radius_km":10842.77,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-1115","host_v_mag":11.983,"eccentricity":0,"uncertainties":{"radius_km":[1275.6200000000001,1849.649],"distance_ly":[81.05638299016508,85.27358495404256],"host_mass_solar":[0.1,0.096],"inclination_deg":[0.11,0.11],"host_radius_solar":[0.203,0.289],"host_temperature_k":[217.88,295.98],"orbital_period_days":[0.0001356,0.0001356]},"host_mass_solar":1.6,"inclination_deg":88.34,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.73,"planets_in_system":1,"discovery_facility":"Kepler","host_temperature_k":8480,"orbital_period_days":23.5540725,"transit_midpoint_bjd":2454977.21245,"equilibrium_temperature_k":1381},"designations":[{"catalog":"Exoplanet","designation":"Kepler-1115 b"},{"catalog":"Host star","designation":"Kepler-1115"}],"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.
