Rare Phenomenon: Mountain-Sized Asteroid Alinda Approaches Earth, Peak Brightness Visible with Binoculars

Once-in-a-Decade Event: Massive Asteroid Alinda Glides Past Earth

last weekend, sky enthusiasts worldwide witnessed a rare astronomical event as the colossal asteroid (887) Alinda made its closest approach to Earth in decades.Spanning an remarkable 2.6 miles (4.2 kilometers) in diameter—comparable to the size of Manhattan—this near-Earth asteroid is among the largest of its kind, presenting a unique opportunity for both professional astronomers and amateur stargazers.

A Close Encounter with a Mountain-Sized Space Rock

On January 8, Alinda passed within 7.6 million miles (12.3 million kilometers) of Earth, a distance roughly 32 times the average gap between our planet and the moon. While this may seem vast, in cosmic terms, it’s considered a relatively close approach. According to NASA’s Jet Propulsion Laboratory, this marks the asteroid’s nearest pass to Earth in decades, with the next comparable event not anticipated until 2087.

Why Alinda Matters

Asteroids like Alinda,with their immense size,have the potential to cause global devastation if they were to collide with Earth,possibly triggering mass extinction events. However, their size also makes them prime candidates for scientific observation.On January 12, Alinda reached its peak brightness at magnitude 9.4. While this level of luminosity isn’t visible to the naked eye, it can be easily spotted using stargazing binoculars.

Gianluca Masi, an astronomer and the head of the Virtual Telescope Project in Italy, noted, “That level of light, not shining enough to be seen with the naked eye, is still a fascinating target for those equipped with basic observational tools.”

How to Spot Alinda in the Night Sky

For those eager to catch a glimpse of Alinda, the asteroid was most visible in the night sky during its peak brightness. Stargazers were advised to use binoculars or a small telescope, as its magnitude 9.4 brightness made it detectable but not overwhelmingly bright. The asteroid’s trajectory and position were tracked using specialized astronomy apps and tools, making it easier for enthusiasts to locate.
