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-110-b","name":"WASP-110 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":896.7995761699576,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":305.8724366,"dec_deg":-44.0587001,"epoch_ra_deg":306.334832,"epoch_dec_deg":-43.97242,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-110","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":9.24386680087495e+26,"mass_msun":0.000464887,"constellation":"Sagittarius","discovered":"2021","featured":false,"url":"https://spacecatalog.org/object/wasp-110-b","radius_km":84146.08374286801,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-110","host_v_mag":12.762,"eccentricity":0,"uncertainties":{"mass_kg":[1.0249872839880724e+26,9.870247916346081e+25],"radius_km":[1715.808015674,2001.7759970260004],"distance_ly":[9.882538244817326,10.101063017887544],"host_mass_solar":[0.022,0.014],"inclination_deg":[0.33,0.38],"host_radius_solar":[0.011,0.011],"host_temperature_k":[50,50],"orbital_period_days":[0.0000016,0.0000016]},"host_mass_solar":0.814,"inclination_deg":88.37,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.853,"planets_in_system":1,"discovery_facility":"Paranal Observatory","host_spectral_type":"G9","host_temperature_k":5392,"orbital_period_days":3.7784022,"transit_midpoint_bjd":2456502.72415,"equilibrium_temperature_k":1158},"designations":[{"catalog":"Exoplanet","designation":"WASP-110 b"},{"catalog":"Host star","designation":"WASP-110"}],"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.
