As usual with Russan media we should consider them unreliable. This kind of stories sometimes also occur in the press here in the west but nothing happens.

Pravda used to be an official government newspaper, in the old Soviet Union. Today, it's a sensationalist tabloid.
This story is about the object 2016 WF9, probably a large comet with most of its ices depleted , so resembling an asteroid. It will pass Earth at a very safe distance of 51 million kilometers, on February 25th.
