Summary:

- The article discusses the asteroid Apophis, which has a small chance of colliding with Earth in 2068. Apophis is a 1,100-foot wide asteroid that was initially thought to have a 2.9% chance of hitting Earth in 2029, but further observations have ruled out that possibility.

- However, the article notes that Apophis still has a 1-in-150,000 chance of hitting Earth in 2068, which may seem small but is still a significant risk given the potential catastrophic consequences of such an impact.

- The article explores the concept of "chaos theory" and how a small change in initial conditions can have a large impact on the future, making it difficult to predict the exact trajectory of Apophis with certainty. The article highlights the importance of continued monitoring and research to better understand the risks posed by Apophis and other potentially hazardous asteroids.
