When travelling in the solar system, asteroids often form into a solid rock like structure whilst passing through the warmer inner solar system planets such as Mars and Jupiter.
The discovery comes following another near miss, when an asteroid came within just 4,000 miles of colliding with Earth on Thursday.
The C0PPEV1 – since renamed 2019 UN 13 – travelled 3,852 miles (6,200km) above the Earth, which makes it one of the closest near-misses in recorded history.
