An asteroid passed dangerously close to Earth – and most people never noticed

A recently discovered asteroid passed extremely close to Earth this week, and it basically went by unnoticed.

An asteroid passed dangerously close to Earth – and most people never noticed

Most people went about their week completely unaware that a newly discovered asteroid had quietly passed close to Earth.

The asteroid, named 2026 JH2, was only detected days before it swept past the planet in what astronomers classify as a close flyby.

It was never considered a threat, but the timing of the discovery has once again raised questions about how many objects in space go unnoticed until the last minute.

The asteroid passed closer than the moon

According to Vice, the asteroid was first spotted on 10 May by researchers involved in the Mount Lemmon Survey, a project focused on tracking near-Earth objects.

By 18 May, it had already made its closest approach to Earth.

Travelling at roughly 20 000 miles (around 32 000 km) per hour, the asteroid passed within about 56 000 miles (around 90 000 km) of the planet – much closer than the moon’s orbit.

In astronomical terms, that is considered an extremely close flyby.

For comparison, the moon sits around 384 000 kilometres from Earth, meaning the asteroid passed well inside that distance.

Scientists also estimate the asteroid to be between 50 and 115 feet wide.

That makes it roughly comparable in height to the Washington Monument.

While not large enough to trigger emergency concerns, it was still big enough to remind astronomers how difficult smaller space objects can be to track consistently.

Why scientists are paying attention

What made this event especially notable was not the asteroid itself, but how late it was discovered.

Astronomers have long warned that many smaller near-Earth objects remain difficult to detect until they reflect sunlight at the right angle or pass directly through telescope observation zones.

Some asteroids also approach from directions near the sun, making them significantly harder to spot using existing systems.

This means there are likely many smaller objects moving through nearby space that are not constantly monitored in real time.

This week’s flyby ultimately caused no danger to Earth. But it served as a reminder that space around our planet is far more active than most people realise.

Objects continue moving silently through the solar system every day, and sometimes one passes surprisingly close before the world even notices it was there.
