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-1422-c","name":"TOI-1422 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":506.00226595353286,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":354.240829,"dec_deg":39.6392793,"epoch_ra_deg":354.571102,"epoch_dec_deg":39.78794,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1422","semi_major_axis_km":30667563.493499994,"periapsis_km":null,"mass_kg":8.361035014907932e+25,"mass_msun":0.0000420489,"constellation":"Andromeda","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-1422-c","radius_km":16646.841,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1422","host_v_mag":10.622,"uncertainties":{"mass_kg":[1.7916503603374138e+25,1.7916503603374138e+25],"radius_km":[892.9340000000001,892.9340000000001],"distance_ly":[2.1428474015990044,2.162416784262009],"host_mass_solar":[0.0355,0.0358],"inclination_deg":[0.19,0.15],"host_radius_solar":[0.013,0.014],"host_temperature_k":[62,62],"semi_major_axis_km":[747989.3535,747989.3535],"orbital_period_days":[0.0002,0.0002]},"host_mass_solar":0.9903,"inclination_deg":89.77,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":1.019,"planets_in_system":2,"discovery_facility":"Roque de los Muchachos Observatory","host_spectral_type":"G2 V","host_temperature_k":5840,"orbital_period_days":34.5633,"transit_midpoint_bjd":2458756.3525,"eccentricity_upper_limit":0.2,"equilibrium_temperature_k":628,"argument_of_periastron_deg":90},"designations":[{"catalog":"Exoplanet","designation":"TOI-1422 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.
