Upsalón Andraiméide
Cuma
An chéad réalta, diomaite den Ghrian, arb eol go bhfuil córas ilphlainéadach aige. Cruthaíodh i 1999 go bhfuil 3 phláinéad, ar a laghad, timpeall air. Tá gach ceann acu níos mó troime ná an Domhan, suas le 5 oiread mhais Iúpatair. Tá an réalta seo níos teo mó gile ná an Ghrian, agus níos óige de 2,600 milliún bliain, meastar. 44 solasbhliain amach uainn.[12]
