There’s something comforting about a map with “You are here” marked on it, but not when the arrow points to a spot where giant asteroids are whizzing by like cannon balls in a pirate movie. NASA has released a map of the inner Solar System showing the orbits of the 1,400 Potentially Hazardous Asteroids (PHA) known as of early this year. According to the agency, the plots show the orbits of asteroids over 460 ft (140 m) in diameter that pass within 4.7 million miles (7.5 million km) of Earth.
