ZyØs
ZyØs is a fictional celestial body located in the Andromeda Galaxy. Its existence was first hypothesized by astrophysicist Dr. Aris Thorne in 2342, based on anomalous energy readings detected by the deep-space observatory Kepler-X. Initial spectral analysis suggests ZyØs is a rogue planet, having been ejected from its parent star system billions of years ago. Its size is estimated to be roughly twice that of Jupiter, with a dense, metallic core and an unusually thin atmosphere composed primarily of exotic gases.
The most striking characteristic of ZyØs is its intermittent electromagnetic field, which fluctuates with extreme irregularity.
