A colossal "potentially hazardous" asteroid, 2008 OS7, is poised to gracefully sweep by Earth on Friday, Feb. 2. This once-in-a-lifetime proximity might be alarming. Still, experts said that we don't have to worry about this space rock.
Football Stadium-Size Wonder in Space
NASA says that the approaching asteroid will pass seven times the distance from Earth to the moon. However, it will not harm anything as it passes on Feb. 2.
Boasting dimensions akin to a football stadium, the formidable 890 feet (271 meters) across asteroid embarks on its journey, ensuring a safe passage at a distance of approximately 1.77 million miles (2.85 million kilometers). This marks its closest approach to Earth in over a century.
While it is described as a football stadium-size asteroid, a separate report from AP News indicates that it is comparable to the size of the Willis Tower in Chicago or the Empire State Building in New York City.

Witness the Flyby in a Live Stream
Those who want to watch the asteroid can witness this cosmic rendezvous firsthand through a live stream courtesy of The Virtual Telescope Project. Set to commence at 1:00 p.m. ET on Feb. 2; the live broadcast promises an immersive experience of the asteroid's celestial journey.
Stellar Speed Display
As it gracefully traverses Earth's vicinity, the asteroid dazzles with a remarkable speed of around 41,000 mph (66,000 km/h), ensuring a fleeting yet breathtaking encounter, according to NASA's Jet Propulsion Laboratory (JPL).
In the cosmic field, 2008 OS7 stands as a celestial giant, measuring approximately half the size of the renowned Bennu-visited and sampled by NASA and significantly dwarfed by the colossal Vredefort meteor, Earth's largest recorded space rock impact.
No Need to Worry About This Asteroid
Despite earning the classification of a "potentially hazardous" asteroid due to its substantial size and proximity, JPL assures that there is no imminent threat of impact. Even in the improbable scenario of a collision, the asteroid lacks the magnitude to be deemed a "planet killer," per Live Science.
Astronomical Predictions and Simulations
2008 OS7's highly elliptical orbit, deviating from a uniform path around the sun, introduces intriguing dynamics. JPL's meticulous simulations based on historical data unveil that this week's encounter is unparalleled in the dataset spanning nearly 300 years, emphasizing its uniqueness.
Scientific Observations and Future Encounters
While direct observations of the asteroid's Earthly flirtations are limited, JPL's simulations, utilizing comprehensive orbital data, forecast every close approach since 1900 and predict encounters until 2198. The upcoming Feb. 2 event is an exceptional chapter in this celestial encounter.
As we gaze at the night sky, this cosmic phenomenon serves as a reminder of the wonders beyond, encapsulating both the precision of astronomical predictions and the continuous exploration of the celestial tapestry enveloping our planet.
The asteroid proves that not all enormous in size are dangerous. It might appear to be a threat, but in reality, it's only a short-lived visitor passing by our planet.
