APOD: Orbits of Potentially Hazardous Asteroids (2013 Aug 12) Image Credit: NASA, JPL-Caltech http://apod.nasa.gov/apod/ap130812.html Explanation: Are asteroids dangerous? Some are, but the likelihood of a dangerous asteroid striking the Earth during any given year is low. Because some past mass extinction events have been linked to asteroid impacts, however, humanity has made it a priority to find and catalog those asteroids that may one day affect life on Earth. Pictured above are the orbits of the over 1,000 known Potentially Hazardous Asteroids (PHAs). These documented tumbling boulders of rock and ice are over 140 meters across and will pass within 7.5 million kilometers of Earth -- about 20 times the distance to the Moon. Although none of them will strike the Earth in the next 100 years -- not all PHAs have been discovered, and past 100 years, many orbits become hard to predict. Were an asteroid of this size to impact the Earth, it could raise dangerous tsunamis, for example. Of course rocks and ice bits of much smaller size strike the Earth every day, usually pose no danger, and sometimes creating memorable fireball and meteor displays. http://photojournal.jpl.nasa.gov/catalog/PIA17041 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130812 #APOD
