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-1235-b","name":"TOI-1235 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":129.27044952614267,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":152.2182549,"dec_deg":69.2766204,"epoch_ra_deg":152.750017,"epoch_dec_deg":69.145013,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1235","semi_major_axis_km":5752038.128415,"periapsis_km":null,"mass_kg":3.995380303552433e+25,"mass_msun":0.0000200933,"constellation":"Ursa Major","discovered":"2020","featured":false,"url":"https://spacecatalog.org/object/toi-1235-b","radius_km":10778.989,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1235","host_v_mag":11.495,"eccentricity":0.049,"uncertainties":{"mass_kg":[4.120795828776051e+24,4.001352471420224e+24],"radius_km":[510.24800000000005,510.24800000000005],"distance_ly":[0.15590274854860336,0.15590274854860336],"eccentricity":[0.035,0.072],"host_mass_solar":[0.024,0.024],"inclination_deg":[0.57,0.62],"host_radius_solar":[0.019,0.019],"host_temperature_k":[51,51],"semi_major_axis_km":[59839.14828,55351.212158999995],"orbital_period_days":[0.00009,0.00009],"argument_of_periastron_deg":[42.9,45.3]},"host_mass_solar":0.63,"inclination_deg":88.9,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.619,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M0.5 V","host_temperature_k":3997,"orbital_period_days":3.444714,"transit_midpoint_bjd":2458683.6145,"equilibrium_temperature_k":775,"argument_of_periastron_deg":78},"designations":[{"catalog":"Exoplanet","designation":"TOI-1235 b"},{"catalog":"Host star","designation":"TOI-1235"}],"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.
