NASA is always keeping an eye on space rocks that get anywhere near Earth, and 2019 has been a relatively calm year in terms of close passes. A recently discovered asteroid is going to make a not-super-close pass of Earth later this week, and while it doesn't pose much of a threat to our planet it's worth mentioning simply because of its size.
The rock, known as 2019 DN, is slated to arrive at its closest point to Earth this coming Friday, March 8th. At its nearest distance the asteroid will still be around 13 lunar distances away. One lunar distance is equal to the space between the Earth and our Moon, so it's clear the asteroid has little chance of disrupting Earth during its flyby, and that's a very good thing considering its size.
NASA estimates the asteroid to be between 91 and 200 meters wide. That's a pretty sizable chunk of space debris as far as the Earth is concerned. It's not the kind of rock that would pose a threat to humanity's existence, but it would definitely cause some commotion if it were to come down above a populated area. ...
That's nuthin'! America survived a close pass by a much bigger lump of debris two-and-a-half years ago - 2016 HRC (Code Name: "Fat Pig").
