Description
Pan ddaw asteroid o’r gofod o fewn trwch blewyn i daro’r ddaear, disgyna darn ohono ger Pegwn y Gogledd. Daw’n amlwg fod y garreg danllyd yn cynnwys metalau newydd sbon sydd â grymoedd rhyfedd iawn yn perthyn iddynt. Wrth i Tintin a’r Capten Hadog fynd ar drywydd yr asteroid gwerthfawr, mae ciwed ddistadl beryglus hefyd am gael gafael arni. Addasiad o L’Etoile Mysterieuse.A fiery asteroid narrowly misses the Earth, but a loose piece of the deep-space missile comes crashing to the ground. It becomes evident that this mineral-rich rock harbours some strange extraterresrial properties which sprout up in Tintin’s face. But an even bigger problem faces the boy reporter when unscrupulous forces head in the same direction.
