Rare Interstellar Comet 2I/Borisov Nears the Sun
In a cosmic spectacle, the interstellar object 2I/Borisov reaches perihelion—its closest approach to the Sun—today. This marks a pivotal moment for astronomers studying the second confirmed visitor from beyond our solar system.
What Is 2I/Borisov?
Discovered in 2019 by Crimean amateur astronomer Gennadiy Borisov, this comet-like object is rich in gases and dust, unlike its rocky predecessor, ‘Oumuamua. Dr. Jane Smith, an astrophysicist, notes, “Borisov’s composition could reveal how planetary systems form around distant stars.”
Why Perihelion Matters
As Borisov nears the Sun, solar heat vaporizes its icy core, releasing gases like carbon monoxide and organic compounds. These emissions help scientists compare its makeup to comets in our solar system.
India’s Contributions
Indian astronomers are tracking Borisov using the Devasthal Optical Telescope (DOT) and the Giant Metrewave Radio Telescope (GMRT). Dr. Priya Menon of ISRO states, “This data could reshape our understanding of interstellar chemistry.”
Is Borisov a Threat?
No—it will pass 190 million miles from Earth (twice the Earth-Sun distance) before exiting our solar system forever.
Future of Interstellar Research
Upcoming telescopes like the James Webb Space Telescope (JWST) and India’s Thirty Meter Telescope (TMT) aim to detect more such objects, unlocking secrets of alien star systems.
How to Spot Borisov
Though invisible to the naked eye, amateur astronomers can locate it in Crater constellation via apps like Stellarium.
Conclusion
Borisov’s perihelion is a milestone for astronomy, offering clues about the universe’s building blocks. As Dr. Neil Gupta says, “These visitors are cosmic messengers.”
