many ways astronomy is a passive science in that astronomers don’t always get to setup the experiment of their choosing. Instead they must wait for Nature to send it just the right circumstances to test out an existing theory. Recently such an occurrence happened when a quarter-mile size rock passed through the Solar System. The rock appears to have origins from outside our Solar System which means it may have been ejected during the early formation process of some other solar system. At least that’s what the solar nebular model for solar system formation suggests. However, all of this presumes that the interstellar rock actually originated from outside our Solar System.For this essay read the articles, Astronomers race to learn from first interstellar asteroid ever seen by Ken Croswell and How astronomers identified the first visitor from another solar system which was posted in the Economist. From these reading you’re tasked with extracting the If…and…then…And/But…Therefore… statement about the question, how do astronomers know that this rock originated from outside the Solar System?To receive credit for the essay you must submit, through Moodle and only Moodle, a five point bullet list with each item a part of the If…and…then… statement. To receive full credit it must be clear that you have read the article which will be evident by clear references to specifics discussed in the article.Readings to use:https://www.nature.com/news/astronomers-race-to-learn-from-first-interstellar-asteroid-ever-seen-1.22925https://www.economist.com/the-economist-explains/2017/11/03/how-astronomers-identified-the-first-visitor-from-another-solar-system
