Explanation: 

Detailed explanation-1: -The Fastest Orbiting Asteroid In The Solar System Has Been Discovered. Astronomers have discovered a new asteroid, dubbed 2021 PH27, which is an object of records.

Detailed explanation-2: -A team of researchers led by Scott Sheppard, a staff scientist at the Carnegie Institution of Science, has discovered the fastest-orbiting asteroid in the solar system.

Detailed explanation-3: -The space rock, known as 2021 PH27, completes one lap around our star every 113 Earth days, its discoverers determined. That’s the shortest orbital period of any known solar system object except the planet Mercury, which takes just 88 days to loop around the sun.

Detailed explanation-4: -Before entry in Earth’s atmosphere, the meteoroid probably had an absolute magnitude (H) of roughly 31. The meteoroid entered at a record speed of 64, 000 ± 1, 600 mph (28.6 ± 0.7 km/s), the fastest fireball on record from which meteorites were later recovered.
