Like &#8216;Oumuamua, Borisov&#8217;s measured hyperbolic trajectory and speed as it falls toward the Sun confirm that its origin is from beyond our Solar System. But while detailed observations indicate &#8216;Oumuamua is a rocky body with differences from known Solar System objects, Borisov is definitely a far wandering comet. Taken on October 12, 2019 this Hubble Space Telescope image of Borisov reveals a familiar looking comet-like activity and concentration of dust around around its nucleus. Not resolved in the image, some estimates suggest the nucleus could be between 2 and 16 kilometers in diameter. At the time of the Hubble image, comet 2I\/Borisov was about 418 million kilometers away. Borisov is still inbound though and will make its closest approach to the Sun on December 7 at a distance of about 300 million kilometers (2 Astronomical units). via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap191018.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>After the 2017 detecton of 1I\/&#8217;Oumuamua, comet 2I\/Borisov has become the second recognized interstellar interloper.
