A new study links the sun's 11-year cycle to accelerated orbital loss, with debris falling faster once sunspot numbers near their cycle peak.

We're only starting to awaken to the passage of interstellar objects through our inner Solar System. So far we know of three, but there are bound to be many more. Do they pose an impact threat to Earth?

NASA warns that thousands of “city-killer” asteroids remain undetected, with only 40% of large near-Earth objects tracked. Experts call for stronger planetary defence systems.

Asteroid 2024 YR4 has a 0.28% chance of hitting Earth in 2032, says NASA. Scientists continue tracking its orbit while assessing potential impact risks.

Earth is no longer at risk of a direct collision with the asteroid 2024 YR4, but an impact on the moon in 2032 could send debris hurtling towards our planet that could take out orbiting satellites

Space rock now has 2.3% risk of collision – up from 1.3% in December – but danger is likely to fall with more data It might not be the world-ending apocalypse foretold in the Netflix drama Don’t...
