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":"lp-714-47-b","name":"LP 714-47 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":171.6104396994417,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":64.1902212,"dec_deg":-12.0848643,"epoch_ra_deg":64.505959,"epoch_dec_deg":-12.018005,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"LP 714-47","semi_major_axis_km":6067689.635592,"periapsis_km":null,"mass_kg":1.6949012408791935e+26,"mass_msun":0.000085239,"constellation":"Eridanus","discovered":"2020","featured":false,"url":"https://spacecatalog.org/object/lp-714-47-b","radius_km":27106.925000000003,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"LP 714-47","host_v_mag":12.492,"eccentricity":0.022,"uncertainties":{"mass_kg":[4.359682543487707e+24,4.598569258199362e+24],"radius_km":[510.24800000000005,637.8100000000001],"distance_ly":[0.3758952253185468,0.3758952253185468],"eccentricity":[0.015,0.022],"host_mass_solar":[0.001,0.001],"inclination_deg":[0.05,0.06],"host_radius_solar":[0.001,0.001],"host_temperature_k":[44,44],"semi_major_axis_km":[4487.936121,4487.936121],"orbital_period_days":[0.000003,0.000003],"argument_of_periastron_deg":[29,220]},"host_mass_solar":0.542,"inclination_deg":87.5,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.536,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M1 V","host_temperature_k":4123,"orbital_period_days":4.052032,"periastron_epoch_bjd":2458439.8,"transit_midpoint_bjd":2458438.38487,"equilibrium_temperature_k":722.8,"argument_of_periastron_deg":-110},"designations":[{"catalog":"Exoplanet","designation":"LP 714-47 b"},{"catalog":"Host star","designation":"LP 714-47"}],"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.
