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-5882-b","name":"TOI-5882 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1357.149733934478,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":311.8886385,"dec_deg":34.7374918,"epoch_ra_deg":312.154624,"epoch_dec_deg":34.835911,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-5882","semi_major_axis_km":12027668.80428,"periapsis_km":null,"mass_kg":4.177772244064542e+28,"mass_msun":0.0210106,"constellation":"Cygnus","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-5882-b","radius_km":73136.315823006,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-5882","host_v_mag":11.315,"eccentricity":0.0339,"uncertainties":{"mass_kg":[1.366649711824839e+27,1.1578560058515997e+27],"radius_km":[2716.696014187,3217.139981553],"distance_ly":[12.804899389159347,13.04299354489257],"eccentricity":[0.0041,0.0041],"host_mass_solar":[0.065,0.055],"inclination_deg":[1.1,0.97],"host_radius_solar":[0.052,0.072],"host_temperature_k":[210,210],"semi_major_axis_km":[194477.23190999997,164557.65777],"orbital_period_days":[0.000014,0.000014],"argument_of_periastron_deg":[4.5,4.9]},"host_mass_solar":1.334,"inclination_deg":88.56,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":2.26,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5920,"orbital_period_days":7.148972,"transit_midpoint_bjd":2459768.8621,"equilibrium_temperature_k":1515,"argument_of_periastron_deg":104.7},"designations":[{"catalog":"Exoplanet","designation":"TOI-5882 b"},{"catalog":"Host star","designation":"TOI-5882"}],"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.
