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":"k2-214-b","name":"K2-214 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":980.5565339676174,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":14.8759777,"dec_deg":4.2277722,"epoch_ra_deg":15.223021,"epoch_dec_deg":4.372836,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"K2-214","semi_major_axis_km":12476462.41638,"periapsis_km":null,"mass_kg":4.090934989437094e+25,"mass_msun":0.0000205739,"constellation":"Pisces","discovered":"2018","featured":false,"url":"https://spacecatalog.org/object/k2-214-b","radius_km":16009.030999999999,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"K2-214","host_v_mag":11.806,"uncertainties":{"radius_km":[446.46700000000004,892.9340000000001],"distance_ly":[13.290872391957295,13.652905971222879],"host_mass_solar":[0.05,0.05],"inclination_deg":[3.0978,1.34613],"host_radius_solar":[0.047,0.047],"host_temperature_k":[100,100],"semi_major_axis_km":[134638.08362999998,134638.08362999998],"orbital_period_days":[0.00051,0.00051]},"host_mass_solar":1.03,"inclination_deg":88.14511,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.236,"planets_in_system":1,"discovery_facility":"K2","host_temperature_k":5875,"orbital_period_days":8.59656,"transit_midpoint_bjd":2457396.6009,"equilibrium_temperature_k":1001},"designations":[{"catalog":"Exoplanet","designation":"K2-214 b"},{"catalog":"Host star","designation":"K2-214"}],"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.
