Asteroids, also known as minor planets, are remnants from the early stages of our solar system's formation approximately 4.6 billion years ago. These rocky and airless objects vary in size, with the largest asteroid being Vesta, measuring about 329 miles (530 kilometers) in diameter. On the other end of the scale, some asteroids are as small as 33 feet (10 meters) across. When considering the collective mass of all asteroids, it is still less than that of Earth's Moon, NASA has revealed.
However, irrelevant of the size, these asteroids can deviate from their orbit and strike planets in the solar system, including Earth. And this can be extremely devastating considering the extinction of the dinosaurs 65 million years ago due to an asteroid strike.
Now, NASA's Jet Propulsion Laboratory has issued an alert regarding a colossal asteroid on a trajectory toward Earth, expected to come dangerously close. Referred to as 2023 HT4, this asteroid measures 250-foot in size. According to NASA, it will pass in very close proximity to Earth tomorrow, May 12. Whenever a Near-Earth Object (NEO) approaches within 4.6 million miles or 7.5 million kilometers of our planet, NASA's Planetary Defense Coordination Office promptly releases a warning. The potential threat posed by the 250-foot-wide asteroid 2023 HT4 remains uncertain, pending further evaluation by NASA.
According to NASA's asteroid data tracker, Asteroid 2023 HT4 is scheduled to pass by Earth tomorrow, May 12, at a close distance of only 3.77 million miles, travelling at a blazing speed of 32166 kmph.
The asteroid, which belongs to the Apollo group, was only recently discovered on April 9, 2023, and The-Sky.org reports that it completes one orbit around the Sun every 981 days.
