In an event stirring both excitement and a heightened sense of cosmic awareness among astronomers and the public alike, a stadium-sized asteroid, known as 2008 OS7, will make a close approach to Earth today, February 2, 2024. This asteroid, recognized for its significant size and its classification as “potentially hazardous” due to its proximity to our planet, presents a unique opportunity for scientific observation while also reminding us of the myriad celestial bodies that orbit within our solar system.

The asteroid in question, 2008 OS7, measures approximately 890 feet (or about 271 meters) in diameter, making it comparable to the length of three football fields laid end to end. Its nearest distance to Earth during this approach is some 1,770,000 miles away, equivalent to around 2,850,000 kilometers. Despite the vastness of these numbers, in the grand scale of space, this distance is relatively small, meriting close attention from those monitoring near-Earth objects (NEOs).

Why Is It Considered “Potentially Hazardous”?

An asteroid is classified as “potentially hazardous” based on criteria that include its size and how close it comes to Earth’s orbit. Specifically, asteroids that are larger than 150 meters in diameter and come closer to Earth than 19.5 times the distance to the moon (about 7.5 million kilometers or 4.6 million miles) fall into this category. Despite the alarming designation, it’s important to note that 2008 OS7’s trajectory is well understood by scientists, and it poses no imminent threat to our planet during this pass.

Scientific Significance

The close approach of 2008 OS7 provides a valuable opportunity for researchers to study a near-Earth object (NEO) of this size in greater detail. Observations can help refine our understanding of its composition, orbit, and whether it has companions. These insights are crucial for enhancing our ability to predict the orbits of NEOs and to develop potential strategies for planetary defense should a future asteroid pose a direct threat to Earth.

Public Interest and Observation

For those interested in catching a glimpse of 2008 OS7, while the asteroid will not be visible to the naked eye, amateur astronomers with the appropriate equipment may be able to observe the asteroid as it makes its close approach. Various space agencies and astronomical organizations around the globe are likely to provide live streams or updates, making it accessible for the public to follow this event from the comfort of their homes.


The flyby of asteroid 2008 OS7 serves as a reminder of the dynamic nature of our solar system and the importance of continued vigilance and research in the field of asteroid tracking and planetary defense. While there is no threat from this particular asteroid, it underscores the need for preparedness and the value of space science in safeguarding our planet against potential future hazards.

  1. Wow! I think it’s time we stepped up planetary defense programs in prep. for future catastrophic asteroid collision events. For all the close calls mankind has had from asteroids, the goverment still seem to be impervious by refusing to provide funds for night sky gazers…

  2. How stealthy! I still can’t believe how this elusive asteroid managed to evade by asteroid-prying eyes…perhaps, I was asleep at the time.

  3. Hahaha. Meanwhile, apophis is on its way. I can imagine the looks on the faces of NASAians when they discover, in time, it’s heading for the roof top of the white house.

    Give me a break, 1,770,00 miles? That’s more than 6 times further away than the moon! Not exactly a “skim” regardless of artist’s fantasy concept.

  5. LOL, you all kill each other every single day; so what’s the diff if a large rock takes out your lights? Get real and do the house flies a favor by going extinct and give them a big final meal of ourselves to them.
