Thankfully, there is nothing to fear tomorrow because NASA’s asteroid trackers expect DF31 to miss Earth entirely.
Asteroid DF31 is a so-called “Near-Earth Object” (NEO), which means its orbit sometimes intersects Earth’s journey around the Sun.
When NEOs threaten to swing by our home planet, NASA’s radar systems calculate their velocity, size and trajectory.
In most cases, NEO comets and asteroids swing by without striking Earth but NASA pays close attention to their paths regardless.
