An asteroid classed by astronomers as "potentially hazardous" is due to make a relatively close—but safe—approach to Earth next week.
The space rock, called 138971 (2001 CB21), is estimated to be up to 3,940 feet in diameter, making it significantly bigger than the tallest building in the world, the Burj Khalifa in Dubai, which stands at around 2,720 feet.
Microscopic view on asteroid collisions could help us understand planet formation -- ScienceDaily
A new way of dating collisions between asteroids and planetary bodies throughout our Solar System's history could help scientists reconstruct how and when planets were born.
A team of researchers, led by the University of Cambridge, combined dating and microscopic analysis of the Chelyabinsk meteorite -- which fell to Earth and hit the headlines in 2013 -- to get more accurate constraints on the timing of ancient impact events.

Strange Glass Balls Found on Moon Hint at Asteroid Impact
China has discovered semi-transparent glass balls on the surface of the moon, and they're thought to be the result of ancient asteroid impacts.
The glass balls were spotted by China's Yutu-2 lunar rover, which landed on the far side of the moon in January, 2019 as part of the Chang'e 4 mission .
Science in a Minute: Asteroid 16 Psyche May Not be as Rich in Iron as Thought
Brown and Purdue University researchers say they found evidence that an asteroid, thought to have unusually high iron content, may not have as much of the metal as thought.
Nagin Cox: The inspiring story of NASA's Nagin Cox, who has an asteroid named after her
Nagin Cox, Tactical Mission Lead on the Perseverance Rover, talks about the Mars 2020 Mission and being a woman in STEM.
NASA's $2.7 billion robotic explorer named Perseverance , completed a year of operations on February 18, 2022.
Cox is also sleeping better, now that she's working on a modified Mars time. For the uninitiated, a Martian day, referred to as sol, is approximately 40 minutes longer than a day on Earth.
