9.8-Foot asteroid nearly hits Earth – Authorities says “No Significant Danger”

A massive asteroid narrowly escaped a collision with Earth, traveling within just 300 miles of the planet’s surface. Researchers only identified the close encounter after it had already gone past. The 9.8-foot (three metre) space rock, called 2025 TF, passed over Antarctica during the early hours of October 1. Moving at an altitude of nearly 265 miles (428 kilometres), the asteroid went closer to Earth than the orbit of the International Space Station (ISS).

Space agencies became aware of the near-miss only hours afterward, when the Catalina Sky Survey found the asteroid. Although a miss this encounter seems to be cautionary, the European Space Agency (ESA) made sure that the planet was never in serious trouble. Due to its size, 2025 TF might have burned up or exploded in the atmosphere rather than hitting the surface. ESA stated:


"Objects of this size pose no significant danger. They can produce fireballs if they strike Earth’s atmosphere, and may result in the discovery of small meteorites on the ground."

Following the asteroid’s passage, ESA’s Planetary Defence Office astronomers discovered it using the Las Cumbres Observatory in Australia. This follow-up enabled scientists to measure its size more precisely and find that 2025 TF passed its closest approach at exactly 01:47:26 BST. ESA emphasized the precision of this examination:

"Tracking down a metre-scale object in the vast darkness of space at a time when its location is still uncertain is an impressive feat. This observation helped astronomers determine the close approach distance and time given above to such high precision."

While the asteroid posed little danger to Earth, its proximity prompted concerns for orbiting spacecraft. Fortunately, no satellites or spacecraft were in the way of 2025 TF as it went within the ISS orbit. Despite the ongoing U.S. government shutdown limiting public updates, NASA has mentioned 2025 TF on its Center for Near-Earth Object Studies website.

How Many Near-Earth Asteroids Have Been Discovered?

As of October 4, 2025, the total number of identified Near-Earth Asteroids (NEAs) is at 39,585, with:

• 11,453 measuring over 140 metres
  
• 877 exceeding 1 kilometre
  

As per NASA's data, 2025 TF is anticipated to return to Earth in 2087, moving at a safe distance of 3,710,795 miles (5,971,946 km). To be stated as a "potentially hazardous" asteroid, a rock must be at least 460 feet (140 metres) in diameter and have an orbit giving it within 4.65 million miles (7.48 million km) of Earth. While 2025 TF crosses this orbital threshold, its small size means it has no real danger.

Detecting the Asteroids

Small asteroids like 2025 TF are difficult to capture, describing why it went unnoticed until after its flyby. Every year, astronomers find thousands of NEAs, measuring from harmless rocks such as 2025 TF to massive “city-killers” like 99942 Apophis. Out of the 39,585 named NEAs, nearly 2,500 are regarded as potentially dangerous, as per the International Astronomical Union (IAU) Minor Planet Center. These objects go through deep scrutiny, and their trajectories are closely supervised to assess impact danger.

However, as 2025 TF demonstrates, even improvised planetary defense systems have restrictions. While most huge asteroids are discovered long before approaching Earth, smaller but riskier space rocks can still go through. In January 2024, for instance, NASA’s Scout impact hazard system found a six-foot (two metre) asteroid moving for Berlin just 95 minutes before impact.

The 2013 Chelyabinsk incident serves as a reminder of the challenges posed by small asteroids. A 66-foot (20 metre) asteroid exploded less than 19 miles (30 km) above the Russian city, producing 30 times the energy of the Hiroshima bomb, destroying more than 7,200 buildings and 1,500 people were hospitalized. The asteroid reached from the direction of the sun, making discovery nearly impossible at the time.

FAQs:

Q1. What is 2025 TF?
2025 TF is a small near-Earth asteroid, approximately 9.8 feet (three metres) in size. It recently moved very close to Earth without causing danger.

Q2. Did 2025 TF hit Earth?
No, it passed within 300 miles of the planet. Researchers only detected it after it had already gone past.
