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-6628-b","name":"TOI-6628 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1045.419252804146,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":225.8370504,"dec_deg":-35.2305793,"epoch_ra_deg":226.25642,"epoch_dec_deg":-35.336079,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-6628","semi_major_axis_km":20046114.6738,"periapsis_km":null,"mass_kg":1.4046122038199732e+27,"mass_msun":0.0007064,"constellation":"Lupus","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-6628-b","radius_km":70062.15983212901,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-6628","host_v_mag":12.9,"eccentricity":0.67,"uncertainties":{"mass_kg":[1.1388747598540324e+26,1.1388747598540324e+26],"radius_km":[4289.519975404,4289.519975404],"distance_ly":[18.848577068250602,19.540028589010095],"eccentricity":[0.016,0.015],"host_mass_solar":[0.06,0.06],"inclination_deg":[0.12,0.12],"host_radius_solar":[0.05,0.06],"host_temperature_k":[142,143],"semi_major_axis_km":[1196782.9656,1047185.0948999999],"orbital_period_days":[0.00001,0.00001],"argument_of_periastron_deg":[2.5,2.2]},"host_mass_solar":0.97,"inclination_deg":88.19,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.01,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5463,"orbital_period_days":18.18424,"transit_midpoint_bjd":2458602.721,"equilibrium_temperature_k":833,"argument_of_periastron_deg":215.8},"designations":[{"catalog":"Exoplanet","designation":"TOI-6628 b"},{"catalog":"Host star","designation":"TOI-6628"}],"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.
