  • Searching Apollo photographs of the Giordano Bruno area is a wonderful pastime. Apollo 16's color-Hasselblad AS16-121-19445 shows the bright rays of Giordano Bruno (and the crater itself) at the lower left part of the frame. See also AS16-121-19434, on which it is captured near the frame's centre.
  • AS08-12-2209 is one of Apollo 8's photographs of Giordano Bruno.

A 22 km wide very fresh impact crater with rays, impact melt and spectral evidence (OMAT) for a very young age. Originally crater counts from Kaguya images suggested a formation age of about 4 million years, but 20 times higher resolution LRO images showed that many of the craters are likely to be secondaries and thus the age is much younger, consistent with observations of an explosion on that part of the Moon on June 18, 1178 (Hartung, 1976).

Additional Information

A lunar vortex and a geometric boulder

  • A peculiar vortex-shaped (or swirl-shaped) arrangement of dark arcs and boulders is noticeable in a flat "lake" at the western part of Giordano Bruno's floor, attached to its western inner slopes. Independently discovered by Danny Caes. Is this a unique formation on the moon's surface? See the LRO's ACT-REACT Quick Map. Warning: to get this vortex in the center of your screen, write 102.62 in the oblong LON quadrangle, and 35.98 in the oblong LAT quadrangle. Choose number 2 in the small M/PIX quadrangle, and hit the button RECENTER. - DannyCaes Jun 12, 2011

  • A remarkable 100 meter diameter boulder with corner of 90 degrees at the shadowed northern part of it is detectable at LON: 102.696, LAT: 36.016, M/PIX: 1. - DannyCaes Jun 12, 2011


  • Giordano Bruno (1548 – February 17, 1600) was an Italian philosopher, priest, cosmologist, and occultist. Bruno is known for his system of mnemonics based upon organized knowledge and as an early proponent of the idea of an infinite and homogeneous universe. Burned at the stake as a heretic by the Roman Inquisition, Bruno is often seen as the first "martyr for science."
  • Discovered in Lunik 3 imaging of farside and named in Atlas of the Far Side of the Moon and approved by the IAU in 1961 (Whitaker, p 232).

LROC Articles

Because Giordano Bruno is a favourite subject of many selenologists, many articles about that ray crater appeared on the LROC site.
