2024 DS14 (Square One)

2024 DS14 (known after the impact as Square One) was classified as a near-Earth object and was a "potentially hazardous asteroid". It was discovered on February 18, 2024 by the Catalina Sky Survey. While originally harmless, it collided into an unknown asteroid around late 2024, altering its path, colliding into the Earth on June 16, 2026 despite international efforts to stop it.

Impact

The asteroid crashed into eastern Australia, in the state of Queensland, near the city of Toowoomba. The impact created a 50 kilometer (30 mile) wide crater, and the impact formed the Toowoomba Crater, which would eventually fill with water over the years and form Lake Cypress. Intense winds were caused by the impact.

However, the climate change as a result of this would be much deadlier, spreading ash and dust into the atmosphere, which evenly spread around the Earth due to the Coriolis Effect, dimming out the sun in many parts of the world, cooling global temperatures, and causing the Modern Ice Age.
