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.

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.

The odds that asteroid 2024 YR4 could hit Earth in 2032 recently spiked from a little more than 1% to 2.3%, but astronomers say not to fret.
