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-1069-b","name":"Kepler-1069 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":2269.9407573038875,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":290.9792378,"dec_deg":47.9889097,"epoch_ra_deg":291.16731,"epoch_dec_deg":48.040478,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-1069","semi_major_axis_km":24813798.813008998,"periapsis_km":null,"mass_kg":1.9051215498254499e+25,"mass_msun":0.00000958113,"constellation":"Cygnus","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kepler-1069-b","radius_km":10204.960000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-1069","host_v_mag":13.234,"eccentricity":0,"uncertainties":{"radius_km":[892.9340000000001,1977.211],"distance_ly":[20.609821507921016,20.984901342295274],"host_mass_solar":[0.052,0.051],"host_radius_solar":[0.079,0.175],"host_temperature_k":[104.94,88.79],"semi_major_axis_km":[176525.487426,176525.487426],"orbital_period_days":[0.0001497,0.0001497]},"host_mass_solar":0.99,"inclination_deg":89.24,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.98,"planets_in_system":1,"discovery_facility":"Kepler","host_temperature_k":5722,"orbital_period_days":23.8990296,"transit_midpoint_bjd":2454984.39964,"equilibrium_temperature_k":823},"designations":[{"catalog":"Exoplanet","designation":"Kepler-1069 b"},{"catalog":"Host star","designation":"Kepler-1069"}],"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":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
