Richie Diehl team charges out of the chute over trucked-in snow at the 2015 ceremonial start of the Iditarod Trail Sled Dog race in downtown Anchorage, Alaska March 7, 2015. The timed portion of the race, which typically lasts nine days or longer, begins on Monday in Fairbanks, about 300 miles (482 km) away. Traditionally held in Willow, the timed start was moved to Fairbanks this year to accommodate an alternate trail selected after race officials deemed sections of the traditional path unsafe.

The second-grader picked up the habit at the age of 3 and now smokes up to three packs a day, using the pocket money he gets from his enabling parents to feed his addiction.

If The Moon Were Replaced With Some Of Our Planets

Our moon is a pretty big object. It's big enough to be a respectable planet in its own right, if it were orbiting the sun instead of the Earth. (Actually, it is orbiting the sun in a nearly perfectly circular orbit, that the Earth only slightly perturbs... but that's a topic for another day.) The Moon is a quarter the diameter of the Earth. Only Pluto has a satellite that is larger, in proportion to the size of the planet it orbits.
