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-160113658-b","name":"TIC 160113658 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":652.821559382725,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":59.4555606,"dec_deg":-41.6320332,"epoch_ra_deg":59.686389,"epoch_dec_deg":-41.554278,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 160113658","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":7.166601441349655e+25,"mass_msun":0.0000360419,"constellation":"Horologium","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/tic-160113658-b","radius_km":22260.575336618003,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 160113658","host_v_mag":12.957,"uncertainties":{"radius_km":[2552.441697821,6119.5949691900005],"distance_ly":[2.7299288814891423,2.749498264152147],"host_mass_solar":[0.109916,0.066987],"inclination_deg":[3.31326,0.92117],"orbital_period_days":[0.00006974358,0.00007392755]},"host_mass_solar":0.76,"inclination_deg":88.61162,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.789834,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4817.31,"orbital_period_days":6.72952262077,"transit_midpoint_bjd":2459167.57026043},"designations":[{"catalog":"Exoplanet","designation":"TIC 160113658 b"},{"catalog":"Host star","designation":"TIC 160113658"}],"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.
