The first asteroid that will approach Earth this weekend has been identified by NASA's Center for Near-Earth Object Studies (CNEOS) as 2020 FK. The 2020 FK space rock is the smallest of the four, estimating only 43 feet in the distance across. As indicated in the agency's database, this asteroid is flying across space and towards Earth with an average speed of over 15,000 miles per hour. While smaller asteroids are known to not be quite a bit of danger since they would in all probability break down in the Earth's atmosphere, the larger space rocks are the ones that we keep on watching eagerly. Based on its current trajectory, Sentry estimated that 2008 UB7 could hit Earth with an impact velocity of over 48,000 miles per hour. CNEOS estimated that this asteroid measures about 52 feet wide.
Both 2020 FK and 2020 FS will visit Earth's vicinity on Saturday.
Almost a year after the cosmic shot, scientists finally had a chance to inspect this first-of-its-kind data - captured by cameras on the spacecraft - to learn about an asteroid roughly 314 million kilometers (195 million miles) away.
On Sunday, Earth will be visited by two asteroids.
According to CNEOS, 2020 FH is the biggest asteroid in the group. It is now moving across the Solar System at a speed of 18,000 miles per hour. However, the threat of an asteroid colliding with Earth can not be entirely ruled out, which is what NASA's CNEOS is out in space to warn us against.
2020 FG is expected to approach Earth from a much closer distance compared to 2020 FH. According to CNEOS, this asteroid will zip past the planet from a distance of only 0.00477 astronomical units or 443,000 miles away.
Due to numerous factors including its current speed and Earth-crossing orbit, Sentry detected a total of 31 potential impacts from the asteroid.
NASA noted that 2008 UB7 is an Apollo asteroid. As they travel around Earth's neighborhood, their orbits occasionally intersect that of the planet as it completes its cycle around the sun.
