00:00:02,502 --> 00:00:06,272
DEAN: THE PLANETS MERCURY, VENUS, EARTH, AND 
MARS HAVE A FEW THINGS IN COMMON.

2
00:00:06,373 --> 00:00:11,244
JAMES: THEY'RE ALL ROUND, ROCKY OBJECTS THAT 
CIRCLE THE SUN AND YOU CAN SEE THEM THIS WEEK.

3
00:00:11,344 --> 00:00:16,149
DEAN: WE HAVE OUR SKY SET TO DECEMBER 15 AT 
ABOUT 5:45PM.

4
00:00:16,249 --> 00:00:20,620
LOW ABOVE THE SOUTHWEST HORIZON, YOU MIGHT 
BE ABLE TO MAKE OUT THE PLANET MERCURY.

5
00:00:20,720 --> 00:00:26,292
JAMES: HIGHER UP IN THE SOUTHWEST IS THE DAZZLINGLY-BRIGHT 
PLANET VENUS AND HIGHER STILL AND OVER TO

6
00:00:26,393 --> 00:00:28,228
THE LEFT IS THE RED PLANET MARS.

7
00:00:28,328 --> 00:00:32,665
JAMES: THIS IS HOW MERCURY, VENUS, EARTH, 
AND MARS REVOLVE AROUND THE SUN.

8
00:00:32,766 --> 00:00:36,136
DEAN: MERCURY IS THE CLOSEST TO THE SUN AND 
MOVES THE FASTEST.

9
00:00:36,236 --> 00:00:38,805
VENUS IS SECOND, EARTH IS THIRD, AND MARS 
IS FOURTH.

10
00:00:38,905 --> 00:00:43,610
JAMES: THE DISTANCE FROM THE SUN DETERMINES 
HOW FAST A PLANET WILL MOVE AND HOW LONG IT

11
00:00:43,710 --> 00:00:46,146
TAKES TO MAKE ONE TRIP AROUND THE SUN.

12
00:00:46,246 --> 00:00:47,814
THAT'S ITS YEAR.

13
00:00:47,914 --> 00:00:50,817
DEAN: BUT DONT SPEND ANOTHER YEAR ON EARTH 
WITHOUT SEEING THE OTHER PLANETS.

14
00:00:50,917 --> 00:00:51,818
SO

15
00:00:51,918 --> 00:00:55,918
BOTH: KEEP LOOKING UP!
