The 365 Days of Astronomy

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

From Feb 10 & 17, 2023.

Today's 2 topics:

- The discovery by Greg Leonard of P/2018 VN2 (Leonard), a Jupiter family comet whose fate is to become a garden variety main belt asteroid.

- Comets Travel Between Stars. An interstellar traveler visits our neighborhood on its tour of the Milky Way. Comet Lemmon will continue on a hyperbolic path into deep space. In 2043 it will be further than the average distance that Pluto is from our Sun. Eons from now comet C/2018 U1 (Lemmon) may enter another solar system and be tracked by intelligent beings as it continues its tour of the Milky Way.
