Uhku
Uhku is a fictional planet located in the Cygnus X-1 system, approximately 6,070 light-years from Earth. It is characterized by its extreme environmental conditions, primarily a highly corrosive atmosphere composed of sulfur compounds and a surface temperature that fluctuates dramatically between scorching heat and sub-zero cold due to its eccentric orbit around a binary star system. The planet's landscape is dominated by vast, acidic oceans and jagged, metallic mountain ranges.
Life on Uhku, if it exists, is theorized to be extremophilic, adapted to survive the harsh chemical
Uhku's unique geological and atmospheric properties make it a subject of interest for xenobiologists and astrophysicists
