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-700-c","name":"TOI-700 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":101.52106491000214,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":97.0957165,"dec_deg":-65.5786149,"epoch_ra_deg":97.112331,"epoch_dec_deg":-65.594836,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-700","semi_major_axis_km":13897642.188029999,"periapsis_km":null,"mass_kg":4.341766039884333e+25,"mass_msun":0.0000218354,"constellation":"Dorado","discovered":"2020","featured":false,"url":"https://spacecatalog.org/object/toi-700-c","radius_km":16583.06,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-700","host_v_mag":13.151,"eccentricity":0.068,"uncertainties":{"radius_km":[829.153,892.9340000000001],"distance_ly":[0.06718821380964915,0.06718821380964915],"eccentricity":[0.049,0.07],"host_mass_solar":[0.02,0.021],"inclination_deg":[0.087,0.071],"host_radius_solar":[0.015,0.017],"host_temperature_k":[65,65],"semi_major_axis_km":[224396.80604999998,224396.80604999998],"orbital_period_days":[0.00002,0.00002],"argument_of_periastron_deg":[120,120]},"host_mass_solar":0.415,"inclination_deg":88.903,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.421,"planets_in_system":4,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M2.5 V","host_temperature_k":3459,"orbital_period_days":16.051137,"transit_midpoint_bjd":2458821.62181,"equilibrium_temperature_k":356,"argument_of_periastron_deg":30},"designations":[{"catalog":"Exoplanet","designation":"TOI-700 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.
