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":"gj-9714-b","name":"GJ 9714 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":66.90152235363612,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":315.4141767,"dec_deg":-32.5250028,"epoch_ra_deg":315.826079,"epoch_dec_deg":-32.419703,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"GJ 9714","semi_major_axis_km":1842896169.1533,"periapsis_km":null,"mass_kg":1.7848065611506471e+28,"mass_msun":0.00897605,"constellation":"Microscopium","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/gj-9714-b","radius_km":79726.25,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"GJ 9714","host_v_mag":9.37,"eccentricity":0.155,"uncertainties":{"mass_kg":[3.217321196557781e+27,5.798770652286642e+27],"distance_ly":[0.08056062529603562,0.08056062529603562],"eccentricity":[0.041,0.073],"host_mass_solar":[0.076,0.076],"inclination_deg":[5.041,4.804],"host_radius_solar":[0.064362,0.054573],"host_temperature_k":[102.97,144.31],"semi_major_axis_km":[333603251.66099995,541993085.5461],"orbital_period_days":[4514.3201,8353.76637],"argument_of_periastron_deg":[28.088,11.389]},"host_mass_solar":0.67,"inclination_deg":155.326,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.662662,"planets_in_system":1,"discovery_facility":"Multiple Observatories","host_spectral_type":"K5V","host_temperature_k":4263,"orbital_period_days":19240.75467,"periastron_epoch_bjd":2443730.985,"equilibrium_temperature_k":47.68,"argument_of_periastron_deg":92.13},"designations":[{"catalog":"Exoplanet","designation":"GJ 9714 b"},{"catalog":"Host star","designation":"GJ 9714"}],"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.
