00:00:02,335 --> 00:00:05,071
JAMES: HAVE YOU EVER WONDERED WHICH SEASON 
IS THE LONGEST OR SHORTEST?

2
00:00:05,171 --> 00:00:09,843
DEAN: MOST SCHOOL KIDS WOULD SAY SUMMER IS 
THE SHORTEST BECAUSE IT JUST FLIES BY.

3
00:00:09,943 --> 00:00:11,277
BUT IS THAT REALLY TRUE???

4
00:00:11,378 --> 00:00:15,382
DEAN: EARTH'S ORBIT IS NOT A PERFECT CIRCLE, 
BUT IS AN ELLIPSE.

5
00:00:15,482 --> 00:00:18,985
SO EARTH ACTUALLY VARIES ITS DISTANCE FROM 
THE SUN DURING THE YEAR.

6
00:00:19,085 --> 00:00:23,323
WHEN IT'S CLOSER TO THE SUN, IT TRAVELS FASTER, 
WHEN IT'S FARTHER AWAY IT TRAVELS SLOWER.

7
00:00:23,423 --> 00:00:27,761
JAMES: AND BELIEVE IT OR NOT, THE EARTH IS 
CLOSEST TO THE SUN IN JANUARY AND TRAVELS

8
00:00:27,861 --> 00:00:31,598
OVER 2,200 MILES PER HOUR FASTER THAN IT DOES 
IN JULY.

9
00:00:31,698 --> 00:00:35,769
SO WINTER IS 89 DAYS LONG, AND SUMMER IS 94 
DAYS LONG.

10
00:00:35,869 --> 00:00:37,637
THEREFORE, SUMMER IS THE LONGEST SEASON!

11
00:00:37,737 --> 00:00:42,075
DEAN: ALSO, IF YOU GO OUTSIDE, ANY NIGHT THIS 
WEEK, ABOUT AN HOUR AFTER SUNSET, AND FACE

12
00:00:42,175 --> 00:00:48,081
SOUTHWEST, HIGH IN THE SKY YOU'LL SEE DAZZLINGLY-BRIGHT 
VENUS AND JUST ABOVE IT AND TO THE LEFT, IS

13
00:00:48,181 --> 00:00:49,382
THE RED PLANET MARS.

14
00:00:49,482 --> 00:00:53,482
BOTH: KEEP LOOKING UP!
