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-836-b","name":"TOI-836 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":89.70083162516964,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":225.0798831,"dec_deg":-24.4542022,"epoch_ra_deg":225.471868,"epoch_dec_deg":-24.561104,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-836","semi_major_axis_km":6313030.14354,"periapsis_km":null,"mass_kg":2.705392044109495e+25,"mass_msun":0.0000136058,"constellation":"Libra","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-836-b","radius_km":10868.2824,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-836","host_v_mag":9.92,"eccentricity":0.053,"uncertainties":{"mass_kg":[5.136064366300586e+24,5.494394438368069e+24],"radius_km":[427.33270000000005,427.33270000000005],"distance_ly":[0.09556381867100582,0.09588997504872256],"eccentricity":[0.042,0.042],"host_mass_solar":[0.041,0.049],"inclination_deg":[0.44,0.44],"host_radius_solar":[0.01,0.01],"host_temperature_k":[154,154],"semi_major_axis_km":[139126.01975099999,139126.01975099999],"orbital_period_days":[0.00001,0.00001],"argument_of_periastron_deg":[92,92]},"host_mass_solar":0.678,"inclination_deg":87.57,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.665,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K V","host_temperature_k":4552,"orbital_period_days":3.81673,"transit_midpoint_bjd":2458599.9953,"equilibrium_temperature_k":871,"argument_of_periastron_deg":9},"designations":[{"catalog":"Exoplanet","designation":"TOI-836 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.
