Campbell's Hydrogen Star is named for 19th century astronomer William Wallace Campbell, an American astronomer and director of the Lick Observatory. A specalist in spectroscopy, Campbell is know for a widely-referenced survey of the spectra of the Wolf-Rayet stars, which had been discovered only 30 years earlier. Campbell's spectra of Wolf-Rayet star #43 were "better defined than those in any other spectra", particularly in the hydrogen bands. He noted the hydrgoen spectra extended widely outside the well-defined area of the star, commenting that "there can be no doubt that the observed appearances are due to envelope of incandescent hydrogen."

This finding was key in establishing the theory that certain Wolf-Rayet stars are surrounded by nebula of ejected gas. The star became known as "Campbell's Hydrogen Star" to astronomers of the following century.

Observation in 3305 found a Wolf-Rayet star of just under one solar mass, and a distant M-class dwarf of 1/2 solar mass. The surrounding hydrogen nebula appears to have vanished, perhaps by the radiation pressure of the star.

The star is high above the galactic plane (1337 Ly). It can be reached without a Fleet Carrier by a ship with 50 ly range using a series of neutron-star boosts, one white-dwarf boost, and several level-3 FSD injections. The route is given below:

Thraikai SE-X d2-0 (White Dwarf) - Thraikai LD-Z d1-0 (72.8 ly)

  • Thraikai OO-X d2-0 (Neutron Star) (131.8 ly)
  • Pleia Aedst TS-U d2-0 (Neutron Star) (76.08 ly)
  • Pleia Aedst RX-U d2-0 (Neutron Star) (145.03 ly)
  • Campbell's Hydrogen Star (114.33 ly)


  • Pleia Aedst NR-W d1-0 (L3 FSD boost) (89.69 ly) then follow reverse steps from Pleia Aedst RX-U d2-0
