Astronomers have upped the odds of an asteroid called 2024 YR4 striking Earth, albeit in 2032, but warn that it will most likely soon be downgraded and miss Earth.

Scientists say the threat of a newly discovered asteroid has risen slightly in the past few weeks, as the world's telescopes rush to track its course.

NASA's James Webb Telescope is set to take a look at the 'city-destroying' asteroid which could hit Earth in 2032. The asteroid, known as '2024 YR4', was discovered by NASA’s Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile on 27 December, last year.
