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-262-b","name":"TOI-262 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":143.28701985851973,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":32.534687,"dec_deg":-31.0706272,"epoch_ra_deg":32.831527,"epoch_dec_deg":-30.943505,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-262","semi_major_axis_km":24384452.9241,"periapsis_km":null,"mass_kg":2.9502509266889415e+25,"mass_msun":0.0000148372,"constellation":"Fornax","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-262-b","radius_km":13202.667,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-262","host_v_mag":8.91,"uncertainties":{"radius_km":[956.715,956.715],"distance_ly":[0.3809506491731563,0.3829075874394568],"host_mass_solar":[0.029,0.029],"inclination_deg":[0.413,0.413],"host_radius_solar":[0.021,0.021],"host_temperature_k":[124,124],"semi_major_axis_km":[299195.7414,299195.7414],"orbital_period_days":[0.00003,0.00003]},"host_mass_solar":0.913,"inclination_deg":89.011,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.853,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K0 V","host_temperature_k":5310,"orbital_period_days":11.14529,"transit_midpoint_bjd":2459136.5766,"equilibrium_temperature_k":584},"designations":[{"catalog":"Exoplanet","designation":"TOI-262 b"},{"catalog":"Host star","designation":"TOI-262"}],"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.
