In an unusual incident, astronomers remained unaware of an asteroid that flew closer to Earth than the Moon, however realised it two days later. It was not only the biggest asteroid to have come within one lunar distance of Earth in 2020 but also the biggest to have gotten this close since 2011. The asteroid 2020 LD is nearly 100 metres in diameter, bigger than India's magnificent monument Taj Mahal.
