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":"k2-32-d","name":"K2-32 d","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":514.2898995113153,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":252.426008,"dec_deg":-19.5430504,"epoch_ra_deg":252.820516,"epoch_dec_deg":-19.589888,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"K2-32","semi_major_axis_km":27558919.740353998,"periapsis_km":null,"mass_kg":4.001352471420224e+25,"mass_msun":0.0000201234,"constellation":"Ophiuchus","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/k2-32-d","radius_km":22221.3004,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"K2-32","host_v_mag":12.304,"eccentricity":0.05,"uncertainties":{"mass_kg":[1.4930419669478448e+25,1.4930419669478448e+25],"radius_km":[822.7749000000001,714.3472],"distance_ly":[4.200894144991655,4.269386984312171],"eccentricity":[0.035,0.053],"host_mass_solar":[0.02,0.02],"inclination_deg":[0.1,0.1],"host_radius_solar":[0.02,0.02],"host_temperature_k":[35,39],"semi_major_axis_km":[215420.933808,227388.763464],"orbital_period_days":[0.00096,0.00101],"argument_of_periastron_deg":[104,105]},"host_mass_solar":0.83,"inclination_deg":89.4,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":0.86,"planets_in_system":4,"discovery_facility":"K2","host_spectral_type":"G9 V","host_temperature_k":5271,"orbital_period_days":31.71701,"transit_midpoint_bjd":2456903.78707,"equilibrium_temperature_k":550,"argument_of_periastron_deg":185},"designations":[{"catalog":"Exoplanet","designation":"K2-32 d"}],"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.
