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-1136-b","name":"TOI-1136 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":275.7202077793816,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":192.1848981,"dec_deg":64.8552755,"epoch_ra_deg":192.466105,"epoch_dec_deg":64.708661,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1136","semi_major_axis_km":7638467.277942,"periapsis_km":null,"mass_kg":2.090258753726983e+25,"mass_msun":0.0000105122,"constellation":"Draco","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-1136-b","radius_km":12118.39,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1136","host_v_mag":9.534,"eccentricity":0.027,"uncertainties":{"mass_kg":[4.1805175074539655e+24,4.7777342942331034e+24],"radius_km":[956.715,1339.401],"distance_ly":[0.5143486076593043,0.5163055459256048],"eccentricity":[0.009,0.009],"host_mass_solar":[0.027,0.027],"inclination_deg":[0.6,0.6],"host_radius_solar":[0.036,0.036],"host_temperature_k":[50,50],"semi_major_axis_km":[134638.08362999998,134638.08362999998],"orbital_period_days":[0.0003,0.0003],"argument_of_periastron_deg":[11,11]},"host_mass_solar":1.022,"inclination_deg":86.4,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.968,"planets_in_system":6,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5770,"orbital_period_days":4.1727,"transit_midpoint_bjd":2458684.7,"equilibrium_temperature_k":1216,"argument_of_periastron_deg":25},"designations":[{"catalog":"Exoplanet","designation":"TOI-1136 b"}],"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.
