A Key Decade

Uranus-Pluto and Uranus-Neptune quadrature alignments appear only a few times per century. When they appear back-to-back we should expect magnitude level changes.

Since 1860 these alignments have occurred in the same or adjacent decades three times:

  • 1860s and 70s: Uranus-90-Neptune; Uranus-90-Pluto
  • 1900s: Uranus-180-Neptune; Uranus-180-Pluto
  • 1950s: Uranus-270-Neptune; Uranus-00-Pluto

 Between 2038 and 2049 we will see:

Uranus-90-Neptune; Uranus-180-Pluto
