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-2986-b","name":"TOI-2986 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1836.7463795480635,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":163.7715605,"dec_deg":-6.4784524,"epoch_ra_deg":164.110817,"epoch_dec_deg":-6.62156,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2986","semi_major_axis_km":6715448.415723,"periapsis_km":null,"mass_kg":5.770298783379874e+26,"mass_msun":0.000290197,"constellation":"Leo","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-2986-b","radius_km":59266.8678345,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2986","host_v_mag":12.633,"uncertainties":{"mass_kg":[1.6323871556713363e+26,1.2717434818967246e+26],"radius_km":[1501.331965879,1644.3160203360003],"distance_ly":[77.15229114889566,84.07985261159928],"host_mass_solar":[0.064,0.074],"inclination_deg":[1.2,0.9],"host_radius_solar":[0.031,0.033],"host_temperature_k":[69,66],"semi_major_axis_km":[131646.126216,143613.955872],"orbital_period_days":[0.0000043,0.0000044]},"host_mass_solar":1.122,"inclination_deg":88.8,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.458,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5906,"orbital_period_days":3.2783662,"transit_midpoint_bjd":2459537.62548,"eccentricity_upper_limit":0.14,"equilibrium_temperature_k":1622},"designations":[{"catalog":"Exoplanet","designation":"TOI-2986 b"},{"catalog":"Host star","designation":"TOI-2986"}],"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.
