Messier 4

70 light-years across. (Warp 6 crossing would take two months from side to side.)

Home to two navigation grade Pulsar’s, one of which is CX-1 a pulsar/neutron star binary. (CX-1 is possibly a Prior artefact)

A higher number of habitable M-class worlds than should be possible in a star cluster of this size.

Messier 4 is 8500 light years from Sol, orbiting above the plain of the ecliptic of the Milky Way, straddling the divide between the Sagittarius and Centaurus arms of the galaxy.

All traffic into and out of Messier 4 is regulated through the use of Phase Space Acceleration gates, operated by the Transit Authority operating out of Canopus Station.
