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":"k2-232-b","name":"K2-232 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":426.351616951327,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":73.7667927,"dec_deg":18.654323,"epoch_ra_deg":74.159129,"epoch_dec_deg":18.697835,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"K2-232","semi_major_axis_km":15492355.489691999,"periapsis_km":null,"mass_kg":7.554573771412133e+26,"mass_msun":0.00037993,"constellation":"Taurus","discovered":"2018","featured":false,"url":"https://spacecatalog.org/object/k2-232-b","radius_km":71492.1229,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"K2-232","host_v_mag":9.822,"eccentricity":0.258,"uncertainties":{"mass_kg":[7.023096219654496e+25,7.023096219654496e+25],"radius_km":[1429.842458,1572.8267038000001],"distance_ly":[2.4755269068700825,2.5048809808645895],"eccentricity":[0.025,0.025],"host_mass_solar":[0.026,0.028],"inclination_deg":[0.11,0.13],"host_radius_solar":[0.024,0.024],"host_temperature_k":[60,60],"semi_major_axis_km":[115190.36043899998,121174.27526699999],"orbital_period_days":[0.000023,0.000023],"argument_of_periastron_deg":[3.8,3.6]},"host_mass_solar":1.188,"inclination_deg":89.14,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.161,"planets_in_system":1,"discovery_facility":"K2","host_temperature_k":6154,"orbital_period_days":11.168454,"periastron_epoch_bjd":2457860.59,"transit_midpoint_bjd":2457825.34978227,"equilibrium_temperature_k":1030,"argument_of_periastron_deg":207},"designations":[{"catalog":"Exoplanet","designation":"K2-232 b"},{"catalog":"Host star","designation":"K2-232"}],"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
