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-1180-b","name":"TOI-1180 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":234.91021717395182,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":214.5557741,"dec_deg":82.1937642,"epoch_ra_deg":214.301916,"epoch_dec_deg":82.069051,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1180","semi_major_axis_km":12087358.354689298,"periapsis_km":null,"mass_kg":5.972167867791379e+25,"mass_msun":0.0000300349,"constellation":"Camelopardalis","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-1180-b","radius_km":19593.523200000003,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1180","host_v_mag":11.017,"eccentricity":0,"uncertainties":{"mass_kg":[3.2249706486073448e+25,3.1652489699294308e+25],"radius_km":[1549.8783,1722.0870000000002],"distance_ly":[0.430852574963818,0.43248335685240175],"host_mass_solar":[0.09,0.09],"inclination_deg":[1.28432,0.57484],"host_radius_solar":[0.05,0.05],"host_temperature_k":[139,139],"semi_major_axis_km":[520899.78577739996,480358.7628176999],"orbital_period_days":[0.000006706,0.000006441]},"host_mass_solar":0.75,"inclination_deg":89.20777,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.73,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4738,"orbital_period_days":9.686760378,"transit_midpoint_bjd":2459950.32735,"equilibrium_temperature_k":638.18,"argument_of_periastron_deg":90},"designations":[{"catalog":"Exoplanet","designation":"TOI-1180 b"},{"catalog":"Host star","designation":"TOI-1180"}],"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.
