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-f","name":"TOI-1136 f","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":275.7202077793816,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":192.1848981,"dec_deg":64.8552755,"epoch_ra_deg":192.466204,"epoch_dec_deg":64.708627,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1136","semi_major_axis_km":26030029.501799997,"periapsis_km":null,"mass_kg":5.793002831757638e+25,"mass_msun":0.0000291338,"constellation":"Draco","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-1136-f","radius_km":23828.038313442,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1136","host_v_mag":9.534,"eccentricity":0.001,"uncertainties":{"mass_kg":[2.2097021110828105e+25,2.3291454684386377e+25],"radius_km":[505.51149537800006,549.777295246],"distance_ly":[0.5143486076593043,0.5163055459256048],"eccentricity":[0.001,0.001],"host_mass_solar":[0.027,0.027],"inclination_deg":[0.4,0.4],"host_radius_solar":[0.036,0.036],"host_temperature_k":[50,50],"semi_major_axis_km":[299195.7414,299195.7414],"orbital_period_days":[0.001,0.001],"argument_of_periastron_deg":[20,20]},"host_mass_solar":1.022,"inclination_deg":89.3,"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":26.321,"transit_midpoint_bjd":2458699.3777,"equilibrium_temperature_k":658,"argument_of_periastron_deg":-45},"designations":[{"catalog":"Exoplanet","designation":"TOI-1136 f"}],"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.
