From July 2025.


Today's 2 topics:


- Recently, my Grandsons, Dane and Hank joined our asteroid
hunting team at the Catalina Sky Survey 60 inch telescope on Mt.
Lemmon. The most interesting of our discoveries, 2017 KJ32 is
only 16 feet in diameter, orbits the Sun once every 315 days, and
can come closer to us than the communications satellites. 


 


- My Catalina Sky Survey teammate Carson Fuls discovered a 33
foot diameter asteroid which has about a 1.1% chance of impacting
the Earth on 569 encounters with our planet between 2045 and
2116. Its name is 2017 LD. It is on the list of the most likely
objects to strike the Earth in the next hundred years as reported
on NASA's Sentry Earth Impact Monitoring table.
