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-2134-c","name":"TOI-2134 c","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":73.7772249522828,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":271.9355015,"dec_deg":39.0729269,"epoch_ra_deg":272.158326,"epoch_dec_deg":39.075967,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2134","semi_major_axis_km":55575608.96505,"periapsis_km":null,"mass_kg":3.481773866922374e+26,"mass_msun":0.000175103,"constellation":"Hercules","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-2134-c","radius_km":46879.035,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2134","host_v_mag":8.933,"eccentricity":0.3125,"uncertainties":{"mass_kg":[1.134711894880362e+25,1.134711894880362e+25],"radius_km":[1148.058,1148.058],"distance_ly":[0.0518588640569622,0.05218502043467895],"eccentricity":[0.01,0.01],"host_mass_solar":[0.027,0.027],"inclination_deg":[0.014,0.014],"host_radius_solar":[0.017,0.017],"host_temperature_k":[50,50],"semi_major_axis_km":[673190.4181499999,673190.4181499999],"orbital_period_days":[0.000041,0.000041],"argument_of_periastron_deg":[2.8,2.8]},"host_mass_solar":0.744,"inclination_deg":89.688,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.709,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K5 V","host_temperature_k":4580,"orbital_period_days":95.85284,"periastron_epoch_bjd":2459721.2,"transit_midpoint_bjd":2459718.96933,"equilibrium_temperature_k":302,"argument_of_periastron_deg":160},"designations":[{"catalog":"Exoplanet","designation":"TOI-2134 c"}],"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.
