Asteroids are part of our environment.An SUV sized space rock has spent eons traveling through the silent vacuum of space. In the past 50 years, without humans being aware of its existence, it has made 29 close approaches to planet Earth and 11 visits to the vicinity our sister planet Venus. In the relatively near future asteroid hunters will be able to find more dspace rocks like this one before they impact Earth and thus be able to issue a warning for a space rock which is about to explode over a populated area.
