Scientists Warn Asteroid 2024 YR4 Could Collide with Moon in 2032

Scientists are closely monitoring asteroid 2024 YR4 after recent research indicated a potential collision with the Moon in 2032. This event could unleash spectacular bright flashes and intense meteor activity visible from Earth. The asteroid, discovered on December 27, 2024, initially raised concerns over a possible impact with our planet. However, further observations have since ruled out the likelihood of an Earth impact during its approach on December 22, 2032.

NASA currently estimates a 4.3% chance of the asteroid striking the Moon. A study published in 2025 on the arXiv preprint server explored various scenarios should the asteroid collide with Earth’s natural satellite. The research was led by Yifei Jiao from the University of California, Santa Cruz, who utilized computer simulations to analyze the asteroid’s trajectory through the inner solar system and its potential impact.

The collision with the Moon is projected to release energy equivalent to 6.5 million tons of TNT. This immense force could generate a flash as bright as the planet Venus, lasting between 200 and 300 seconds. The expected impact time is 10:19 AM EST (15:19 UTC), making it observable across regions including East Asia, Oceania, Hawaii, and western North America.

Interestingly, there is a slim chance of the impact occurring on the Moon’s dark side, estimated at 2.85%. Nevertheless, approximately 70% of the Moon will be illuminated at the time of impact, maximizing visibility for observers.

In addition to the immediate flash, the impact could trigger thousands of secondary flashes as debris falls back to the lunar surface. These secondary events are expected to be less intense and may be challenging to observe without specialized equipment. The study predicts that up to 100 million kilograms of lunar material could be ejected into space, potentially leading to extreme meteor storms days or weeks after the impact.

As researchers continue to monitor asteroid 2024 YR4, the implications of a lunar collision remain a compelling area of study. The potential for observable phenomena offers a unique opportunity for both scientific exploration and public interest in astronomical events.
