Podaljšana petstrana girobirotunda je eno izmed Johnsonovih teles (J43). Kot že njegovo ime kaže, ga lahko dobimo s pomočjo podaljševanja "petstrane girobirotunde" ali ikozidodekaedra tako, da dodamo desetstrano prizmo med njegovi skladni polovici. Z vrtenjem petstrane rotunde (J6) za 36º preden vstavimo prizmo, dobimo podaljšano petstrano ortobirotundo (J42).

V letu 1966 je Norman Johnson (rojen 1930) imenoval in opisal 92 teles, ki jih imenujemo Johnsonova telesa.
