The asteroid will be closest to Earth on the morning of April 29.

NASA's orbital calculations suggest the closest approach of about 16.36 lunar distances (LD) will occur at 10.56am BST (9.56am UTC, 4.56am EST).

The space agency estimates the rock is flying through space at speeds of about 8.7km per second or 19,461mph (31,320kmh).

The asteroid is also estimated to measure in the range of 1.1 miles to 2.54 miles (1.5km to 4.1km) in diameter.

Dr Masi snapped his pictures of the asteroid on March 16.

The pictures were taken with a robotic telescope dubbed Elena, over 10 180-second exposures.

Dr Masi said: "The image on the top shows the asteroid like a dot of light, with the stars leaving short trails on the background.

"In that case we aligned the frames used to create the final image considering the motion of the asteroid, slowly moving across the sky.

"The image on the bottom was, more ordinarily, aligned on the stars, so only the asteroid is trailing, while all the stars around are perfectly tracked."

KEY POINTS

  • Three asteroids will approach Earth next week
  • The biggest asteroid in the group is over 220 feet wide
  • All three asteroids follow Earth-crossing orbits

NASA’s automated asteroid tracking system has detected three space rocks that are expected to fly past Earth next week. According to the agency’s Center for Near-Earth Object Studies (CNEOS), the approaching asteroids have natural orbits that are known to intersect the planet’s path.

The first asteroid that will pay Earth a visit next week has been identified as . This asteroid has an estimated diameter of 223 feet, making it the largest space rock in the group. As indicated in CNEOS’ database, this asteroid is currently flying towards Earth at a velocity of over 17,000 miles per hour.

According to CNEOS, 2008 UB95 is expected to debut in Earth’s neighborhood on March 11 at 8:08 a.m. EST. During this time, the asteroid will fly past Earth from about 0.04726 astronomical units or roughly 4.4 million miles away.

NASA noted that both 2018 RF6 and 2020 CA3 are classified as Apollo asteroids. This means that these two space rocks follow very wide orbits around the Sun. From time to time, their orbits cross the path of Earth.

2008 UB95, on the other hand, is an Aten asteroid. Although Aten asteroids also follow Earth-crossing trajectories, they follow narrower orbits compared to Apollo space rocks.
