Asteroid bigger than two cricket pitches is hurtling towards Earth again on September 15

NASA has issued an alert about a massive asteroid named 2024 ON, measuring 720 feet in diameter (roughly bigger than two cricket pitches), which is expected to closely approach Earth on September 15, 2024, at a distance of 620,000 miles. Its speed of 25,000 miles per hour and potential implications have captured significant attention.

Detected by NASA’s Near-Earth Object Observations Program, asteroid 2024 ON has been under close surveillance due to its considerable size and speed. This program is dedicated to identifying and tracking objects near Earth. The asteroid will pass at a distance approximately 2.6 times the distance between Earth and the Moon, making its closest approach.

The Jet Propulsion Laboratory (JPL) in Pasadena, California, has been instrumental in tracking and analyzing the asteroid's movements. Using advanced radar and optical telescopes, JPL scientists have collected detailed data on 2024 ON’s size, shape, and composition. These details are vital for understanding the potential impact and developing strategies to mitigate any threat.


Despite its size of 720 feet—comparatively the height of a 60-story building—and high speed, NASA deems the collision likelihood low. Nonetheless, NASA's Planetary Defense Coordination Office (PDCO) underscores the necessity for continuous vigilance and readiness. The PDCO’s role involves identifying and tracking near-Earth objects and strategizing deflection or mitigation efforts.

The discovery of asteroid 2024 ON has ignited interest within the scientific community. Researchers from the European Space Agency (ESA) and various universities are working with NASA to study its composition. This collaboration aims to uncover more about the materials forming these celestial bodies and provide insights into the early solar system.

Public curiosity about 2024 ON is high, with NASA offering updates and information via its website and social media platforms. The asteroid’s approach, visible from the Northern Hemisphere, will be live-streamed through the Virtual Telescope Project.

The approach of 2024 ON highlights the importance of global cooperation in space exploration and planetary defense. Countries increasingly acknowledge the need for joint action to address potential threats from near-Earth objects. Collaborative missions like the Asteroid Impact & Deflection Assessment (AIDA), involving NASA and ESA, are essential for developing effective protection strategies.

As September 15, 2024, draws closer, scientists and researchers will continue to monitor 2024 ON's trajectory and collect data. This research not only ensures safety but also advances understanding of the universe and the dynamic processes shaping it. Studying asteroids like 2024 ON provides valuable insights into the history and forces of our solar system over billions of years.

“We are closely monitoring asteroid 2024 ON to gather as much data as possible,” emphasized the Jet Propulsion Laboratory.

“International cooperation is key to addressing threats posed by near-Earth objects,” reiterated the Planetary Defense Coordination Office.

Astronomers and space enthusiasts continue to keep a keen eye on developments, focusing on the implications and advances stemming from the study of 2024 ON.
