Another well-known case of a UFO sighting, known as the Zeta Reticuli Incident, took place in 1961. The Zeta Reticuli system consists of two yellow main sequence stars of the spectral types G3-5V and G2V. The constellation’s brightest star, the yellow giant or bright giant Alpha Reticuli, shines at magnitude 3.315.
This led to the establishment of the exchange program. G-type supergiants can have more than nine solar-masses and a luminosity that can reach more than 10,000 times that of the Sun. Because of the southerly location of the system, it is not visible north of the tropics. Dzêta Herculis, étoile triple - NASA/ADS Hercules.

At that orbital distance, it would complete an orbit every 320 days. Read; View source; History; ZWI Export; For other stars with this Bayer designation, see φ Lupi. Both stars share similar proper motions and distances confirming that they indeed form a wide binary star. A 2002 study of stars with low chromospheric ages and high kinematical ages suggested that both stars in the Zeta Reticuli system were about 2 billion years old. One of the aliens’ spacecraft purportedly crash landed in Roswell, New Mexico, in June or July 1947.
