    From 721-foot monster to 22-foot dwarf, 5 asteroids to come very close to Earth
    1/5 Asteroid 2022 YS5 - NASA’s Planetary Defense Coordination Office has warned that the asteroid, named Asteroid 2022 YS5, will make its closest approach to Earth today, January 13, at a distance of 5.9 million kilometers. It is nearly as big as an aircraft, with a width of 130 feet. Asteroid 2022 YS5 is already hurtling towards the planet at a speed of 21506 kmph.  (Wikimedia Commons)
    2/5 Asteroid 2014 LJ - A relatively small asteroid with a size of 22 feet will fly past Earth by a very close margin tomorrow, January 14. The asteroid, named Asteroid 2014 LJ, will make its closest approach with the planet at a distance of 1.8 million kilometers. The asteroid is travelling towards the planet at a blistering speed of 12515 kilometers per hour. (Pixabay)
    3/5 Asteroid 2022 YH3 – Another asteroid named 2022 YH3 will make its closest approach to Earth tomorrow, January 14 at a distance of 7.2 million kilometers. The asteroid, with a width of 290, is travelling at a staggering speed of 58580 kilometers per hour towards the planet. (Pixabay)
    4/5 Asteroid 2012 BV13 - NASA has issued an alert against another asteroid named Asteroid 2012 BV13. This asteroid is particularly concerning due to its monstrous size. According to NASA, it has a size ranging anywhere between 327 feet and 721 feet, making it nearly as big as a football field! It is expected to fly past Earth closely on January 16 at a distance of 1.5 million kilometers. The asteroid is already on its way towards Earth, travelling at a speedy 24042 kilometers per hour.  (WikiMedia Commons)
    5/5 Asteroid 2020 BP - NASA has warned that an asteroid named Asteroid 2020 BP is heading for Earth and is expected to pass by the planet closely on January 20. Asteroid 2020 BP is already on its way towards us travelling at a fearsome speed of 60966 kilometers per hour. The asteroid, with a width between 62 feet and 141 feet, will make its closest approach to Earth a distance of just 1.9 million kilometers.  (Pixabay)

    NASA has detected a small yet potentially hazardous asteroid on January 11, 2023, which has been dubbed Asteroid 2023 AH and it is all set to make a very close approach towards Earth today. As per NASA's asteroid data tracker, Asteroid 2023 AH measures around 20-foot in diameter, and will fly past the Earth today January 15 at 15:05. This near-Earth asteroid belongs to the Apollo group and makes one orbit around the Sun in 528 days.

    NASA's CNEOS detected that the asteroid is making its journey at a fiery speed of 17221 km per hour. “At this time, the asteroid moves away from the Sun at a maximum distance of 23million kilometers and approaches it at a minimum distance of 144 million kilometers,” mentioned. However, the most worrying part is that this small asteroid will make an uncomfortably close approach towards the Earth at a distance of just 440000 miles. While the average distance between Earth and the moon is 239,000 miles or 385,000 kilometers.

    Why this 20-foot asteroid is a potential threat to Earth

    NASA's Jet Propulsion Laboratory's Center for NEO Studies maintains an impact risk assessment list of all the near-Earth objects that will make relatively close approaches to Earth. NASA's JPL has given the tag of potentially hazardous objects to all the space rocks that approach within 4.6 million miles of Earth and have a size larger than about 150 meters. The close distance towards the Earth is what makes this 20-foot asteroid a potential threat to Earth. A small deviation from its orbit can lead to a catastrophic consequences on Earth.

    NASA-supported ground-based telescopes such as Pans-STARRS1 in Maui, Hawaii, the Catalina Sky Survey near Tucson, Arizona, and a space-based telescope called NEOWISE, astronomers can keep a close watch on these near-Earth objects. Moreover, NASA also has an impact monitoring system in place which uses an algorithm called Sentry-II to calculate the impact risk of these asteroids.
