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-2992-b","name":"TOI-2992 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1767.8523678829556,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":164.3165643,"dec_deg":-32.3224375,"epoch_ra_deg":164.634003,"epoch_dec_deg":-32.46594,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2992","semi_major_axis_km":6492547.58838,"periapsis_km":null,"mass_kg":6.32075491718988e+27,"mass_msun":0.0031788,"constellation":"Hydra","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-2992-b","radius_km":87720.683764892,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2992","host_v_mag":12.603,"uncertainties":{"mass_kg":[7.40268593905121e+26,7.40268593905121e+26],"radius_km":[3217.139981553,3217.139981553],"distance_ly":[41.28487429138538,43.26790506790318],"host_mass_solar":[0.1,0.07],"inclination_deg":[0.9,1.1],"host_radius_solar":[0.047,0.046],"host_temperature_k":[110,100],"semi_major_axis_km":[194477.23190999997,134638.08362999998],"orbital_period_days":[0.0000019,0.0000019]},"host_mass_solar":1.21,"inclination_deg":86.1,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.545,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":6000,"orbital_period_days":3.007812,"transit_midpoint_bjd":2459503.55851,"eccentricity_upper_limit":0.089,"equilibrium_temperature_k":1726},"designations":[{"catalog":"Exoplanet","designation":"TOI-2992 b"},{"catalog":"Host star","designation":"TOI-2992"}],"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.
