Introduction to the Interstellar Comet 2I/Borisov
The International Astronomical Union (IAU) has recently recognized a spotted comet as an official interstellar object. Originally known as Comet C/2019, it has now been formally named 2I/Borisov. This renaming signifies that this is the second interstellar object ever identified by scientists. The first was 1I/’Oumuamua, discovered in October 2017.
Distinguishing Features of 2I/Borisov
Scientists established the origins of Borisov through tracking its location for a sufficient period of time to study its trajectory. Objects that are part of our solar system usually revolve around the sun in elliptical orbits, but interstellar bodies follow a hyperbolic path. The IAU confirmed that the path of 2I/Borisov is more hyperbolic than any other comet studied so far, clearly stating its interstellar nature.
Why Is It Named Borisov?
The comet was named Borisov in honor of its discoverer, the Crimean astronomer Gennady Borisov.
About the International Astronomical Union
Established in 1919 and headquartered in Paris, France, the International Astronomical Union or IAU is committed to promoting and safeguarding the science of astronomy. Its functions range from research, communication, education and development through international cooperation. The IAU holds the authoritative responsibility for naming planetary features within our solar system.

The Significance of 2I/Borisov
The recognition of 2I/Borisov brings about a revelation that such interstellar objects might be more common than we previously believed. This discovery opens up new avenues in exploring processes beyond our own planetary systems. The analysis of interstellar objects can offer unique insights into the evolution and composition of different star systems and exoplanets without us having to physically travel there.
These celestial bodies have likely been travelling across the cosmos for centuries. In their journey, they collect various materials or experience encounters with different forces, which leave a mark. Studying their surface and composition can provide unprecedented understanding about the interstellar medium.
