Earth has a new mini-moon, but it’s leaving by early 2027

If you like looking up at Kuwait’s clear winter sky, here’s something small but fun happening above us right now. Earth has quietly picked up a new, tiny companion – and it’s not sticking around for long.

Scientists call it a mini-moon, and this one has the name 2026 QQ8. It won’t be visible to the naked eye, but it’s a good reason to pay a little more attention to the night sky this season, especially with several sky events happening over Kuwait this November.

So what exactly is a mini-moon?

A mini-moon, more correctly called a temporary satellite, is a small object from space that gets caught by Earth’s gravity for a while. It’s not a real moon like the one we see every night. It’s a passing visitor that Earth’s pull grabs for a short time before it moves on.

The International Astronomical Union’s Minor Planet Center, the body that tracks and names these objects, reported the discovery of 2026 QQ8 on 29 October 2026. Researchers then worked backwards and found that the rock had already been orbiting Earth since April 2026, months before anyone spotted it.

Where did 2026 QQ8 come from, and where is it going?

2026 QQ8 normally travels around the sun on its own path, taking about 359 days to complete one loop. That’s close to one Earth year. Around once every ten years, it passes close to our planet. This time, it came close enough that Earth’s gravity managed to hold onto it for a while.

According to the Minor Planet Center, the closest 2026 QQ8 will get to Earth during this visit is about 353,000 miles (568,000 kilometres). That’s roughly 110,000 miles (177,000 kilometres) further away than the Moon usually is from Earth. So even at its closest, it stays well clear of us.

Scientists expect the rock to break free from Earth’s gravity sometime around December 2026, based on the orbit data, though separate modelling on typical mini-moon behaviour suggests it could linger slightly longer, into January 2027.

Is this dangerous, and how big is it really?

No, it isn’t dangerous. 2026 QQ8 is only about 6 feet, or 2 metres, across. Even in the unlikely case that it ever got pulled towards Earth, it would almost certainly burn up completely in the atmosphere long before reaching the ground.

It’s actually bigger than most mini-moons. Earlier modelling this year found that the average temporary satellite is only about 75 centimetres (30 inches) wide, roughly the size of a large suitcase. That same research suggested these objects usually stay captured for around nine months on average, which roughly matches the April-to-January timeline expected for 2026 QQ8.

Some past studies have suggested Earth may have up to six mini-moons orbiting it at any given time, many of them likely small fragments broken off from our actual Moon over the years.

If a bigger rock, around 10 feet (3 metres) wide, were ever captured the same way, researchers say it could stay in Earth’s orbit for 10 to 20 years instead of just months. That hasn’t happened with 2026 QQ8, but it shows how much size affects how long these visitors stick around.

What this means if you’re watching the sky from Kuwait

For most of us in Kuwait, this won’t change anything we can see with our own eyes. 2026 QQ8 is too small and too far to spot without a professional telescope, so don’t expect to catch it during an evening walk along the Gulf Road.

But if you’ve been following our coverage of local stargazing, this fits nicely alongside other things worth watching this month, including the recent alignment of the Moon, Jupiter and Mars over Kuwait in early November.
