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-294329732-b","name":"TIC 294329732 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":617.5216546224418,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":109.1177907,"dec_deg":-58.2371507,"epoch_ra_deg":109.232426,"epoch_dec_deg":-58.284105,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 294329732","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":2.9681674302923154e+25,"mass_msun":0.0000149273,"constellation":"Carina","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/tic-294329732-b","radius_km":13246.820417746001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 294329732","host_v_mag":12.23,"uncertainties":{"radius_km":[1189.328197641,1421.920347552],"distance_ly":[2.2537405700226967,2.2733099526857017],"host_mass_solar":[0.132893,0.085229],"inclination_deg":[2.39584,1.19542],"orbital_period_days":[0.00008746034,0.00008044472]},"host_mass_solar":0.89,"inclination_deg":88.31142,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.920172,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5201.93,"orbital_period_days":9.7565876181,"transit_midpoint_bjd":2459336.13943753},"designations":[{"catalog":"Exoplanet","designation":"TIC 294329732 b"},{"catalog":"Host star","designation":"TIC 294329732"}],"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.
