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-3235-b","name":"TOI-3235 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":237.47772017933806,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":207.4738488,"dec_deg":-46.0665139,"epoch_ra_deg":207.888312,"epoch_dec_deg":-46.200063,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-3235","semi_major_axis_km":4052606.3172629997,"periapsis_km":null,"mass_kg":1.2622528588083584e+27,"mass_msun":0.000634805,"constellation":"Centaurus","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-3235-b","radius_km":72707.36378719701,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-3235","host_v_mag":15.16,"uncertainties":{"mass_kg":[4.745311502377886e+25,4.745311502377886e+25],"radius_km":[3145.6479862150004,3145.6479862150004],"distance_ly":[1.7188441105672378,1.7436319952737103],"host_mass_solar":[0.02,0.02],"inclination_deg":[0.046,0.046],"host_radius_solar":[0.016,0.016],"host_temperature_k":[68,68],"semi_major_axis_km":[68815.02052199999,68815.02052199999],"orbital_period_days":[4.1e-7,4.1e-7]},"host_mass_solar":0.3939,"inclination_deg":88.14,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.3697,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M V","host_temperature_k":3388.8,"orbital_period_days":2.59261842,"transit_midpoint_bjd":2459690.00173,"eccentricity_upper_limit":0.029,"equilibrium_temperature_k":604},"designations":[{"catalog":"Exoplanet","designation":"TOI-3235 b"},{"catalog":"Host star","designation":"TOI-3235"}],"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.
