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-2136-b","name":"TOI-2136 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":108.81587845401484,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":281.1763433,"dec_deg":36.5631318,"epoch_ra_deg":281.411378,"epoch_dec_deg":36.590174,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2136","semi_major_axis_km":8527078.6299,"periapsis_km":null,"mass_kg":3.8042709317831085e+25,"mass_msun":0.0000191322,"constellation":"Lyra","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-2136-b","radius_km":13968.039,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2136","host_v_mag":14.32,"eccentricity":0,"uncertainties":{"mass_kg":[1.367626441724226e+25,1.463181127608888e+25],"radius_km":[1084.277,1084.277],"distance_ly":[0.20955547268300764,0.20955547268300764],"host_mass_solar":[0.02,0.02],"inclination_deg":[0.4,0.3],"host_radius_solar":[0.02,0.02],"host_temperature_k":[100,100],"semi_major_axis_km":[897587.2241999999,897587.2241999999],"orbital_period_days":[0.000016,0.000018]},"host_mass_solar":0.34,"inclination_deg":89.4,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.34,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M4.5 V","host_temperature_k":3342,"orbital_period_days":7.851928,"transit_midpoint_bjd":2459017.7043,"equilibrium_temperature_k":395,"argument_of_periastron_deg":90},"designations":[{"catalog":"Exoplanet","designation":"TOI-2136 b"},{"catalog":"Host star","designation":"TOI-2136"}],"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.
