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":"gaia22dkvl-b","name":"Gaia22dkvL b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":4142.185997002642,"distance_method":"NASA Exoplanet Archive sy_dist (Wu+ 2024, 2024AJ....168...62W)","ra_deg":151.769,"dec_deg":-66.1808889,"epoch_ra_deg":151.94831,"epoch_dec_deg":-66.311668,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Gaia22dkvL","semi_major_axis_km":209437018.97999996,"periapsis_km":null,"mass_kg":1.1217916384741385e+27,"mass_msun":0.000564165,"constellation":"Carina","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/gaia22dkvl-b","radius_km":89931.21,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Gaia22dkvL","uncertainties":{"mass_kg":[9.870247916346081e+25,2.8851493913913287e+26],"distance_ly":[815.3909442918585,1402.4724241819968],"host_mass_solar":[0.078,0.155],"semi_major_axis_km":[50863276.038,115190360.439]},"host_mass_solar":1.145,"stars_in_system":1,"discovery_method":"Microlensing","planets_in_system":1,"discovery_facility":"European Space Agency (ESA) Gaia Satellite"},"designations":[{"catalog":"Exoplanet","designation":"Gaia22dkvL b"},{"catalog":"Host star","designation":"Gaia22dkvL"}],"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.
