Title: Travelers in the Night Eps. 717 & 718: Fuls III & Vulcan

Organization: Travelers in The Night

Description: Today’s two stroy:

  • Recently my Catalina Sky Survey teammate Carson Fuls discovered his third comet, Comet C/2018 R4 (Fuls). It is now on its way back into deep space. Given the climate change Earth is experiencing it is hard to predict the state of our planet and humanity when Comet Fuls returns in 7,500 AD.
  • In the fictional Star Trek series, Vulcan, Spock’s home planet was imagined to orbit the A component of the triple star system 40 Eridani [Eri-dani ]. Recently astronomers using the Dharma Planet Survey 50 inch telescope on Mt. Lemmon, Arizona have discovered that there is indeed an actual planet, named HD26965 b, with mass of 8.5 times that of Earth orbiting the star 40 Eridani A once every 42.38 days.

Bio: Dr. Al Grauer is currently an observing member of the Catalina Sky Survey Team at the University of Arizona.  This group has discovered nearly half of the Earth approaching objects known to exist. He received a PhD in Physics in 1971 and has been an observational Astronomer for 43 years. He retired as a University Professor after 39 years of interacting with students. He has conducted research projects using telescopes in Arizona, Chile, Australia, Hawaii, Louisiana, and Georgia with funding from NSF and NASA.

He is noted as Co-discoverer of comet P/2010 TO20 Linear-Grauer, Discoverer of comet C/2009 U5 Grauer and has asteroid 18871 Grauer named for him.
