Earth Faces ‘Close Call’ as Massive Asteroid the Size of Two Football Pitches Nears

By: Georgia | Published: Sep 03, 2024

This September, get ready for a celestial close call as an asteroid the size of two football fields zooms past Earth. 

Dubbed ‘2024 ON’, this massive space rock, stretching 720 feet across, is scheduled to pass within just 620,000 miles of our planet on September 15. It’s one of the biggest near-Earth visitors we’ll see this year.

Catch a Glimpse of '2024 ON'

If you’re in the northern hemisphere and have access to a telescope or even a good pair of binoculars, mark your calendar. ‘2024 ON’, thanks to its impressive size, should be clearly visible as it makes its journey past Earth.

The Double Asteroid Redirection Test (DART) is their latest experiment, aiming to see if we can nudge a potentially dangerous asteroid off its collision course with Earth. This mission is key to our future safety from asteroid impacts.

What Is '2024 ON'?

Made up of rock and metals such as nickel and iron, ‘2024 ON’ is a relic from the dawn of the solar system over 4.6 billion years ago.

The Speedy New York Visitor

Traveling at a blistering 34,000 miles per hour, the meteor that illuminated New York’s skies took a steep dive “at just 18 degrees from vertical, passing over the Statue of Liberty before disintegrating 29 miles above midtown Manhattan.”

Close Call in Space

When astronomers talk about a ‘close call’, they mean objects like ‘2024 ON’ that come alarmingly close to Earth.
