StuthanGasan:

S' e a' chiad phlanaid a tha ann amMearcar (Beurla:Mercury). Tha e tioram le aile glè thana, agus bidh na laithean aige gu math fada, uime sin, a tha aon taobh uabhasach teth, agus an taobh eile uabhasach fuar agus dorch. Chan eilfadag aige.

S' e am planaid as lugha le cuairt den 88 làithean aige.

Tha an teòthachd air uachdar air a' dol eadar −180 agus 430 °C.
