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-82-b","name":"WASP-82 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":899.0957170690835,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":72.6605916,"dec_deg":1.8938365,"epoch_ra_deg":73.009632,"epoch_dec_deg":1.940189,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-82","semi_major_axis_km":6687024.820289999,"periapsis_km":null,"mass_kg":2.220816912701557e+27,"mass_msun":0.00111688,"constellation":"Orion","discovered":"2015","featured":false,"url":"https://spacecatalog.org/object/wasp-82-b","radius_km":115817.239098,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-82","host_v_mag":10.073,"eccentricity":0,"uncertainties":{"mass_kg":[3.7962682268402685e+26,3.7962682268402685e+26],"radius_km":[9293.975977000002,9293.975977000002],"distance_ly":[9.964077339246511,10.18260211231673],"host_mass_solar":[0.37,0.37],"inclination_deg":[1.65,1.65],"host_radius_solar":[0.16,0.16],"host_temperature_k":[90,90],"semi_major_axis_km":[104718.50949,104718.50949],"orbital_period_days":[0.000002,0.000002]},"host_mass_solar":1.48,"inclination_deg":87.9,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":2.1,"planets_in_system":1,"discovery_facility":"SuperWASP","host_spectral_type":"F5","host_temperature_k":6480,"orbital_period_days":2.70579,"transit_midpoint_bjd":2458217.09214,"equilibrium_temperature_k":2190},"designations":[{"catalog":"Exoplanet","designation":"WASP-82 b"},{"catalog":"Host star","designation":"WASP-82"}],"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.
