NASA is currently monitoring four asteroids that are expected to approach Earth on Tuesday. According to the space agency’s Center for Near Earth Object Studies (CNEOS), one of the incoming asteroids will approach Earth from a distance that’s closer than that of the Moon.

The first asteroid that will fly past Earth tomorrow is called 2019 UB8. As indicated in CNEOS’ database, this asteroid is currently flying towards Earth at an average speed of about 24,000 miles per hour. It has an estimated diameter of around 32 feet.

2019 UB8 will fly past Earth on Oct. 29 at 2:30 a.m. EDT. During its approach, the asteroid will be about 0.00127 astronomical units or roughly 118,000 miles from the planet’s center. This means that asteroid will pass by Earth at a much closer distance than that of the Moon.

The second asteroid that will visit Earth’s neighborhood tomorrow is called 2019 UL5. According to CNEOS, this asteroid is about 59 feet wide and is flying at an average velocity of almost 12,000 miles per hour.

CNEOS predicted that the asteroid will approach Earth on Oct. 29 at 7:50 a.m. EDT from a distance of 0.00994 astronomical units or roughly 923,000 miles away.

Trailing behind 2019 UL5 is an asteroid that has been identified as 2019 UT8. As indicated in CNEOS’ database, this asteroid is flying across space with an average speed of about 35,000 miles per hour. The agency estimated that the asteroid is about 72 feet wide.

2019 UT8 is expected to zip past the planet on Oct. 29 at 5:42 p.m. EDT. During its approach, the asteroid will be about 0.00711 astronomical units or roughly 661,000 miles from the planet’s center.

The last asteroid that will visit Earth’s vicinity tomorrow is called 2019 UB2. This space rock is currently moving towards Earth at an average speed of about 19,000 miles per hour. CNEOS noted that it has an estimated diameter of around 131 feet.

The agency predicted that 2019 UB2 will approach Earth on Oct. 29 at 6:20 p.m. EDT from a distance of around 0.03878 astronomical units or roughly 3.6 million miles away.
