Asteroid 2024 YR4

Asteroid YR4 2024 is a near-Earth asteroid discovered in December 2024. It is an Apollo-type asteroid, which means it orbits the sun in an elliptical orbit that intersects the Earth's orbit.  It made news earlier this year when the probability of YR4 hitting the Earth was raised to 3.1% in February 2025, warranting nations to take note. However, the object's exact path is yet to be confirmed, and it is expected to most likely miss the Earth and the moon in late 2032.  Read the infographic to know more.
