Interstellar Crusher

Interstellar Crusher. What a name! What is it? It has to be cool whatever it is?

Interstellar Crusher is a custom Python3 code running on Windows Subsystem for Linux. It continuously monitors the Possible Comet Confirmation Page and computes orbits of newly discovered minor bodies using Bill Gray’s Find_Orb (https://github.com/Bill-Gray/find_orb/commit/ abe3f5847aad4c39f1d82239bf343c876b3d1bd0). Detection of a possible interstellar object triggers an alarm that is sent via e-mail.

Now, two years later, on September 8, 2019, a computer program nicknamed Interstellar Crusher created by astronomers at Jagiellonian University in Krakow, Poland that scanned tirelessly through online data of newly-found comets and asteroids, issued a red alert and notified the team of a possible second hyperbolic object arriving from interstellar space some two years after our first interstellar visitor, the infamous ‘Oumuamua.

“This code was written specifically for this purpose, and we really hoped to receive this message one day. We only didn’t know when’, said Piotr Guzik. The body had been first spotted by Gennady Borisov a week earlier, although its identity had been unknown at that time. A closer investigation into the object’s orbit confirmed its exosolar origin, making it the second-known interstellar interloper.

How and why do some comets like Oumuamua have non gravitational acceleration? How does this effect how their orbits and origin are crushed?
