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-3135-b","name":"TOI-3135 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":723.0006271760367,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":207.8592276,"dec_deg":-69.7725635,"epoch_ra_deg":208.390024,"epoch_dec_deg":-69.90558,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-3135","semi_major_axis_km":7114874.730492,"periapsis_km":null,"mass_kg":1.9550683377494224e+27,"mass_msun":0.000983232,"constellation":"Circinus","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-3135-b","radius_km":87077.255743069,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-3135","host_v_mag":11.79,"uncertainties":{"mass_kg":[5.124936419343146e+26,5.6943737992701615e+26],"radius_km":[2144.759987702,2144.759987702],"distance_ly":[4.438988300724878,4.497696448713892],"host_mass_solar":[0.047,0.042],"inclination_deg":[0.12,0.12],"host_radius_solar":[0.019,0.019],"host_temperature_k":[140,150],"semi_major_axis_km":[109206.44561099999,94246.658541],"orbital_period_days":[0.0000013,0.0000013]},"host_mass_solar":1.044,"inclination_deg":85.69,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.985,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5890,"orbital_period_days":3.7065585,"transit_midpoint_bjd":2459595.16441,"eccentricity_upper_limit":0.24,"equilibrium_temperature_k":1292},"designations":[{"catalog":"Exoplanet","designation":"TOI-3135 b"},{"catalog":"Host star","designation":"TOI-3135"}],"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.
