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-6130-b","name":"TOI-6130 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":720.4207302282972,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":339.2050832,"dec_deg":16.8271941,"epoch_ra_deg":339.532702,"epoch_dec_deg":16.966379,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-6130","semi_major_axis_km":5385523.345199999,"periapsis_km":null,"mass_kg":1.9930308297445566e+27,"mass_msun":0.00100232,"constellation":"Pegasus","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-6130-b","radius_km":91509.75977293,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-6130","host_v_mag":11.21,"eccentricity":0.036,"uncertainties":{"mass_kg":[1.1388747598540324e+26,1.1388747598540324e+26],"radius_km":[2144.759987702,2144.759987702],"distance_ly":[8.40178828998331,8.600743680390524],"eccentricity":[0.018,0.018],"host_mass_solar":[0.08,0.08],"host_radius_solar":[0.03,0.03],"host_temperature_k":[50,50],"semi_major_axis_km":[299195.7414,299195.7414],"orbital_period_days":[0.000002,0.000002],"argument_of_periastron_deg":[30,30]},"host_mass_solar":1.31,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.51,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"F","host_temperature_k":6110,"orbital_period_days":2.392679,"transit_midpoint_bjd":2459849.63919,"equilibrium_temperature_k":1750,"argument_of_periastron_deg":42},"designations":[{"catalog":"Exoplanet","designation":"TOI-6130 b"},{"catalog":"Host star","designation":"TOI-6130"}],"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.
