1. Asteroid 2024 ON’s close approach

A 720-foot-wide asteroid, 2024 ON, will pass just 620,000 miles from Earth on September 15—a close call in cosmic terms.

2. Size comparison: two football fields

The asteroid is roughly the size of two football fields, making it one of the larger near-Earth objects to pass by this year.

3. Visible from Earth

Skygazers in the northern hemisphere can catch a glimpse of 2024 ON through telescopes or binoculars during its flyby.

4. NASA’s asteroid tracking

NASA closely monitors near-Earth objects like 2024 ON to refine predictions and assess potential risks.

5. Rare opportunity for astronomers

The flyby offers a unique chance for scientists to gather data on the asteroid’s composition and movement.

6. Understanding asteroid composition

Asteroids like 2024 ON vary in makeup, from rocky materials to metals like nickel and iron, formed over 4.6 billion years ago.

7. Potentially hazardous asteroids

Objects like 2024 ON are closely watched, as they are larger than 150 meters and pass within 4.6 million miles of Earth.

8. NASA’s deflection mission

NASA’s DART mission is testing technology to alter an asteroid’s course, part of ongoing efforts to protect Earth.
