Tiny Asteroid Skims Earth, Flying Lower Than Satellites and ISS
In a rare celestial event, a small asteroid made an extraordinarily close pass by Earth on October 1, swooping just 300 kilometres above Antarctica’s icy surface—lower than many satellites and even beneath the orbit of the International Space Station (ISS).
The asteroid, designated C15KM95, was discovered only hours before its flyby. Measuring less than two meters in diameter, it posed no threat to life or property. Still, its near miss has caught the attention of astronomers worldwide for its unusual proximity.
Typically, satellites in low Earth orbit travel at altitudes around 340 km, while the ISS orbits at about 400 km. This means the asteroid’s path was closer to Earth than the space station itself. Fortunately, experts confirmed there was no chance of collision, as the ISS does not pass over Antarctica.
While C15KM95 was too small to survive entry into Earth’s atmosphere—it would have burned up harmlessly—its discovery highlights a serious challenge in planetary defense. The asteroid was detected only hours before its closest approach, leaving little room for tracking or warnings. Such small near-Earth objects, often dark and fast-moving, remain notoriously difficult to monitor despite technological advances.
For scientists, the flyby was not just a near miss but a valuable learning moment. It underlines the urgent need for stronger early detection systems as human dependence on satellites and space infrastructure continues to grow.
“This kind of event is rare, but it reminds us how much of Earth’s cosmic neighborhood still escapes our notice,” one expert said. “Every close call is a wake-up call to sharpen our monitoring techniques.”
C15KM95 may have posed no danger, but its close approach serves as a timely reminder: the sky above us remains full of surprises.
