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":"toi-2382-b","name":"TOI-2382 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1418.5193179656605,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":356.3751852,"dec_deg":-16.114124,"epoch_ra_deg":356.722677,"epoch_dec_deg":-15.964959,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2382","semi_major_axis_km":8826274.371299999,"periapsis_km":null,"mass_kg":1.4046122038199732e+27,"mass_msun":0.0007064,"constellation":"Aquarius","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-2382-b","radius_km":78140.75581557101,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2382","host_v_mag":11.814,"uncertainties":{"mass_kg":[4.745311499391802e+26,4.745311499391802e+26],"radius_km":[3646.092017362,5433.391964593001],"distance_ly":[49.667093198705686,53.336352448019056],"host_mass_solar":[0.065,0.064],"inclination_deg":[0.28,0.24],"host_radius_solar":[0.038,0.041],"host_temperature_k":[83,81],"semi_major_axis_km":[149597.8707,149597.8707],"orbital_period_days":[0.0000032,0.0000032]},"host_mass_solar":1.26,"inclination_deg":84.11,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.417,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":6033,"orbital_period_days":4.6612061,"transit_midpoint_bjd":2459215.4585,"eccentricity_upper_limit":0.18,"equilibrium_temperature_k":1426},"designations":[{"catalog":"Exoplanet","designation":"TOI-2382 b"},{"catalog":"Host star","designation":"TOI-2382"}],"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.
