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-2093-c","name":"TOI-2093 c","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":270.0516099346646,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":302.7375229,"dec_deg":70.8696532,"epoch_ra_deg":302.714605,"epoch_dec_deg":70.948584,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2093","semi_major_axis_km":38446652.7699,"periapsis_km":null,"mass_kg":9.43602523111038e+25,"mass_msun":0.0000474551,"constellation":"Draco","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-2093-c","radius_km":14669.63,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2093","host_v_mag":11.925,"eccentricity":0,"uncertainties":{"mass_kg":[2.269423789760724e+25,2.1499804324048965e+25],"radius_km":[765.3720000000001,765.3720000000001],"distance_ly":[0.5163055459256048,0.5182624841919053],"host_mass_solar":[0.034,0.034],"inclination_deg":[0.075,0.088],"host_radius_solar":[0.029,0.029],"host_temperature_k":[85,85],"semi_major_axis_km":[2692761.6725999997,2543163.8019],"orbital_period_days":[0.00017,0.00017]},"host_mass_solar":0.745,"inclination_deg":89.577,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.729,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K5 V","host_temperature_k":4426,"orbital_period_days":53.81149,"transit_midpoint_bjd":2458751.6122,"equilibrium_temperature_k":329,"argument_of_periastron_deg":0},"designations":[{"catalog":"Exoplanet","designation":"TOI-2093 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.
