Gagarin Radiation Belt
The Gagarin Radiation Belt was an area of space that surrounded the Loracus system. 

At one time, the radiation belt made travel to this system all but impossible until the system's primary star became relatively stable prior to 2151. ()

In 2164, the Federation starship  went missing in the belt. ()

It was later theorized in 2263 of the alternate reality by  that the ship experienced a wormhole displacement to account for its remote distance, for the 22nd century, from Earth after the ship was discovered on the planet Altamid. ()
