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":"wasp-70-a-b","name":"WASP-70 A b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":725.2250136720648,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":315.4771912,"dec_deg":-13.4333821,"epoch_ra_deg":315.846676,"epoch_dec_deg":-13.328011,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-70 A","semi_major_axis_km":7259984.6650709985,"periapsis_km":null,"mass_kg":1.1198531412252971e+27,"mass_msun":0.00056319,"constellation":"Aquarius","discovered":"2014","featured":false,"url":"https://spacecatalog.org/object/wasp-70-a-b","radius_km":83215.07070000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-70 A","host_v_mag":10.786,"eccentricity":0,"uncertainties":{"mass_kg":[4.175739773159732e+25,4.175739773159732e+25],"radius_km":[7290.1683,5217.2858],"distance_ly":[9.184563596503494,9.41939618845955],"host_mass_solar":[0.042,0.042],"inclination_deg":[0.65,1.24],"host_radius_solar":[0.089,0.064],"host_temperature_k":[79,79],"semi_major_axis_km":[92750.679834,92750.679834],"orbital_period_days":[0.0000047,0.0000047]},"host_mass_solar":1.106,"inclination_deg":87.12,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":1.215,"planets_in_system":1,"discovery_facility":"SuperWASP","host_spectral_type":"G4","host_temperature_k":5763,"orbital_period_days":3.7130203,"transit_midpoint_bjd":2455736.50348,"equilibrium_temperature_k":1387},"designations":[{"catalog":"Exoplanet","designation":"WASP-70 A b"},{"catalog":"Host star","designation":"WASP-70 A"}],"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.
