Something has slung these in from the Ort Cloud. Its gonna escalate. Better be it Mars than us ,possibly, time will tell. I smell Wormood, Destroyer, or whatever you wanna call it. You know, the planet or star that every ancient civilization had a name for...the civilizations that built pyramids all over the globe, all separately, who somehow knew it was gonna return. Identified NEOs will skyrocket (no pun) in the next few years. This is just the beginning.
