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":"kelt-14-b","name":"KELT-14 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":815.7855935088959,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":108.301409,"dec_deg":-42.4097623,"epoch_ra_deg":108.515189,"epoch_dec_deg":-42.454811,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"KELT-14","semi_major_axis_km":4495416.014535,"periapsis_km":null,"mass_kg":2.4372042016314522e+27,"mass_msun":0.00122571,"constellation":"Puppis","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kelt-14-b","radius_km":124610.77021470001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"KELT-14","host_v_mag":11.001,"eccentricity":0,"uncertainties":{"mass_kg":[6.074029162944429e+25,6.074029162944429e+25],"radius_km":[3360.1297763000002,3360.1297763000002],"distance_ly":[4.986931015289007,5.052162290832356],"host_mass_solar":[0.039,0.039],"inclination_deg":[0.3,0.3],"host_radius_solar":[0.03,0.03],"host_temperature_k":[130,130],"semi_major_axis_km":[46375.339917,46375.339917],"orbital_period_days":[0.0000026,0.0000032]},"host_mass_solar":1.239,"inclination_deg":78.3,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.52,"planets_in_system":1,"discovery_facility":"KELT-South","host_spectral_type":"G4","host_temperature_k":5720,"orbital_period_days":1.7100566,"transit_midpoint_bjd":2456665.22401,"equilibrium_temperature_k":1970},"designations":[{"catalog":"Exoplanet","designation":"KELT-14 b"},{"catalog":"Host star","designation":"KELT-14"}],"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.
