(Audio & Text) Fascinating Story About an Asteroid That Might Have Broken Off the Moon

Recently, the popular YouTube channel Bright Side shared an intriguing story about an asteroid that is believed to have broken off the Moon and is currently very close to Earth. This asteroid, named Kama Olawa, or 2016 HO3, spins incredibly fast and orbits near our planet. For simplicity, let’s call it HO3.

Astronomers discovered this celestial body on April 27, 2016. Compared to other asteroids, HO3 is quite small. On Earth, it would be the size of a small building or roughly half the size of the London Eye Ferris Wheel. The asteroid was found in Hawaii, and its name roughly translates to "a fragment of something that seems to wobble." After further study, scientists hypothesized that this asteroid might be a chunk of the Moon, blasted into space millions of years ago.

Could HO3 Pose a Threat to Earth?

Luckily, there’s no need to panic about HO3. When astronomers first spotted this piece of Moon debris, they quickly calculated its orbit. It turns out that it won’t collide with Earth anytime soon. In fact, HO3 is considered a "quasi-satellite" and will continue to follow a stable orbit around the Sun, staying near Earth for at least the next 300 years. While its path is unusual—constantly looping closer, farther, up, and down—it remains predictable. Sometime in the 24th century, HO3’s orbit is expected to shift into a "horseshoe" shape, gradually moving away from Earth.

Although there is a theoretical possibility that HO3 could collide with Earth, Venus, the Sun, or even be ejected from the solar system millions of years from now, it remains one of the smallest and most stable asteroids ever discovered.

A Glimpse into the Past and Future of Asteroids

The story of HO3 also opens up fascinating discussions about celestial impacts. For instance, the Moon's Giordano Bruno crater—named after an Italian philosopher—is thought to have been formed by a massive collision about 4 million years ago. Some even speculate that this impact might have ejected HO3 into space. Interestingly, historical records from 1178 describe five monks in Canterbury witnessing what they described as the Moon splitting with sparks and flames. Though this event was once thought to be linked to the Giordano Bruno crater, scientists later determined that the crater is much older than medieval times.

Astronomers are eager to learn more about HO3. Back in 2017, students proposed sending a spacecraft to study the asteroid. The China National Space Administration is planning a mission in 2025 to send a robotic probe to collect samples from HO3 and bring them back to Earth.

An Exciting Future for Skywatchers

HO3 may be too small and dim to see with the naked eye—it measures between 130 and 330 feet in diameter—but there are other fascinating asteroids to watch out for. In 2029, an asteroid named Apophis, measuring over 1,200 feet wide, will pass so close to Earth that it will be visible to the naked eye. This once-in-a-thousand-year event caused significant concern back in 2004, when initial calculations suggested a small chance of collision. However, updated data ruled out any risk of impact in both 2029 and its future close approach in 2036.

Astronomers remain vigilant, tracking the Apollo asteroid group, to which both HO3 and Apophis belong. These near-Earth objects, with their orbits crossing Earth’s path, remind us of the ever-present dynamic forces in our solar system.

While the idea of asteroid impacts may sound alarming, scientists assure us that a catastrophic collision like the one that wiped out the dinosaurs 66 million years ago is extremely rare. In the meantime, the study of asteroids like HO3 offers valuable insights into the history of our solar system and the possibility of life traveling between celestial bodies on these "space Ubers."
