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":"tic-67686059-b","name":"TIC 67686059 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":812.791477961456,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":19.884337,"dec_deg":-35.2930148,"epoch_ra_deg":20.193992,"epoch_dec_deg":-35.151675,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 67686059","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":4.317877368413168e+25,"mass_msun":0.0000217152,"constellation":"Sculptor","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/tic-67686059-b","radius_km":16527.310431082,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 67686059","host_v_mag":12.992,"uncertainties":{"radius_km":[2008.3334491980002,2675.5874376],"distance_ly":[6.024108296428251,6.115432082188939],"host_mass_solar":[0.082198,0.119667],"inclination_deg":[3.53948,1.21101],"orbital_period_days":[0.00004337664,0.00003803822]},"host_mass_solar":0.86,"inclination_deg":88.31448,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.820458,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5090.09,"orbital_period_days":3.52163529551,"transit_midpoint_bjd":2458404.38247947},"designations":[{"catalog":"Exoplanet","designation":"TIC 67686059 b"},{"catalog":"Host star","designation":"TIC 67686059"}],"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.
