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-1614-b","name":"Kepler-1614 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":3885.142155724076,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":284.8713893,"dec_deg":49.7758867,"epoch_ra_deg":285.043918,"epoch_dec_deg":49.812271,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-1614","semi_major_axis_km":7046059.70997,"periapsis_km":null,"mass_kg":1.6901235065849604e+25,"mass_msun":0.00000849987,"constellation":"Draco","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kepler-1614-b","radius_km":9503.369,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-1614","host_v_mag":16.01,"eccentricity":0,"uncertainties":{"radius_km":[956.715,765.3720000000001],"distance_ly":[139.9537016782546,150.61901522959212],"host_mass_solar":[0.058,0.047],"host_radius_solar":[0.065,0.047],"host_temperature_k":[46.14,50.38],"orbital_period_days":[0.00003022,0.00003022]},"host_mass_solar":0.79,"inclination_deg":88.54,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.76,"planets_in_system":1,"discovery_facility":"Kepler","host_temperature_k":5121,"orbital_period_days":3.9466141,"transit_midpoint_bjd":2454965.24559,"equilibrium_temperature_k":981},"designations":[{"catalog":"Exoplanet","designation":"Kepler-1614 b"},{"catalog":"Host star","designation":"Kepler-1614"}],"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.
