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-46432937-b","name":"TIC 46432937 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":295.29187353703026,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":83.8689794,"dec_deg":-14.5971909,"epoch_ra_deg":84.174619,"epoch_dec_deg":-14.579307,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 46432937","semi_major_axis_km":3089196.029955,"periapsis_km":null,"mass_kg":6.073998719221506e+27,"mass_msun":0.0030547,"constellation":"Lepus","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/tic-46432937-b","radius_km":84932.49575536701,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 46432937","host_v_mag":14.268,"uncertainties":{"mass_kg":[2.0879370597323927e+26,2.0879370597323927e+26],"radius_km":[2144.759987702,2144.759987702],"distance_ly":[0.6751437018736588,0.6784052656508263],"host_mass_solar":[0.029,0.029],"inclination_deg":[0.14,0.09],"host_radius_solar":[0.0091,0.0091],"host_temperature_k":[57,57],"semi_major_axis_km":[52359.254745,52359.254745],"orbital_period_days":[8.7e-8,8.7e-8]},"host_mass_solar":0.563,"inclination_deg":84.35,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":0.5299,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":3572,"orbital_period_days":1.44044527,"transit_midpoint_bjd":2459952.28894,"eccentricity_upper_limit":0.009,"equilibrium_temperature_k":872},"designations":[{"catalog":"Exoplanet","designation":"TIC 46432937 b"},{"catalog":"Host star","designation":"TIC 46432937"}],"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.
