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-1468-c","name":"TOI-1468 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":80.6907616907446,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":16.6538724,"dec_deg":19.2249195,"epoch_ra_deg":17.012549,"epoch_dec_deg":19.36877,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1468","semi_major_axis_km":12877384.709856,"periapsis_km":null,"mass_kg":2.4485888257944653e+25,"mass_msun":0.0000123143,"constellation":"Pisces","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-1468-c","radius_km":13559.8406,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1468","host_v_mag":12.5,"eccentricity":0.111,"uncertainties":{"mass_kg":[6.569384654570517e+24,6.569384654570517e+24],"radius_km":[593.1633,586.7852],"distance_ly":[0.15231502839371916,0.15296734114915264],"eccentricity":[0.084,0.15],"host_mass_solar":[0.0079,0.0081],"inclination_deg":[0.062,0.14],"host_radius_solar":[0.01,0.01],"host_temperature_k":[44,45],"semi_major_axis_km":[97238.61595499999,97238.61595499999],"orbital_period_days":[0.000026,0.000025],"argument_of_periastron_deg":[73,100]},"host_mass_solar":0.3527,"inclination_deg":89.22,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.3714,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M3.0 V","host_temperature_k":3376,"orbital_period_days":15.532477,"transit_midpoint_bjd":2458766.9267,"equilibrium_temperature_k":338.1,"argument_of_periastron_deg":130},"designations":[{"catalog":"Exoplanet","designation":"TOI-1468 c"},{"catalog":"Host star","designation":"TOI-1468"}],"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.
