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-767-b","name":"Kepler-767 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":7341.87790931721,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":291.5791562,"dec_deg":38.0358066,"epoch_ra_deg":291.813822,"epoch_dec_deg":38.088955,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-767","semi_major_axis_km":87873789.24918,"periapsis_km":null,"mass_kg":2.1320639288015225e+26,"mass_msun":0.000107225,"constellation":"Lyra","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kepler-767-b","radius_km":42350.584,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-767","host_v_mag":15.678,"eccentricity":0,"uncertainties":{"radius_km":[3507.9550000000004,5485.166],"distance_ly":[454.3358341594236,516.99047431881],"host_mass_solar":[0.058,0.063],"host_radius_solar":[0.077,0.12],"host_temperature_k":[124.14,163.45],"orbital_period_days":[0.0003086,0.0003086]},"host_mass_solar":0.96,"inclination_deg":90,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.94,"planets_in_system":1,"discovery_facility":"Kepler","host_temperature_k":5694,"orbital_period_days":161.5280101,"transit_midpoint_bjd":2455031.00109,"equilibrium_temperature_k":366},"designations":[{"catalog":"Exoplanet","designation":"Kepler-767 b"},{"catalog":"Host star","designation":"Kepler-767"}],"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.
