From LiveScience:
An asteroid discovered Tuesday (April 9) made an extremely close, but harmless, pass by planet Earth today (April 11).
Asteroid 2024 GJ2 is roughly the size of a car and, since its discovery this week, astronomers calculated that the space rock would graze by Earth at a mere 12-thousand-mile (19.3-thousand-kilometer) distance — that’s just three percent the distance between the Earth and the moon. 2024 GJ2 measures between 2.5 and 5 meters (8.2 and 16 feet), according to the European Space Agency (ESA). This means it’s an asteroid with a weight-class that would have burned up in Earth’s atmosphere, if its orbit happened to intersect ours more directly.
