00:00:02,535 --> 00:00:04,304
GREETINGS STAR GAZERS!

2
00:00:04,404 --> 00:00:08,441
THIS WEEK IS THE GREAT WESTERN ELONGATION 
FOR VENUS AND THE AFTERMATH OF THE GREAT EASTERN

3
00:00:08,541 --> 00:00:11,111
ELONGATION FOR MERCURY!

4
00:00:11,211 --> 00:00:15,448
ELONGATION IS A MEASURE OF WHERE THE PLANETS 
ARE RELATIVE TO THE SUN AND US ON EARTH!

5
00:00:15,548 --> 00:00:19,652
PUT YOUR ARMS OUT LIKE THIS, POINT AT THE 
SUN WITH ONE HAND, AND VENUS WITH YOUR

6
00:00:19,753 --> 00:00:20,653
OTHER HAND.

7
00:00:20,754 --> 00:00:23,023
THIS ANGLE IS THE ELONGATION!

8
00:00:23,123 --> 00:00:27,060
AND BOTH VENUS AND MERCURY ARE HITTING THEIR 
GREATEST ELONGATIONS THIS TIME OF YEAR -- OR

9
00:00:27,160 --> 00:00:29,896
THEIR LARGEST ANGLES RELATIVE TO THE SUN.

10
00:00:29,996 --> 00:00:36,036
VENUS WILL REACH ABOUT FORTY FIVE DEGREES 
BEFORE SUNSET, AND MERCURY WILL PEAK AT ABOUT

11
00:00:36,136 --> 00:00:38,004
TEN DEGREES BEFORE SUNRISE.

12
00:00:38,104 --> 00:00:43,276
REMEMBER TEN DEGREES IS ABOUT THE SAME AS 
THE HEIGHT OF A FIST ON AN OUTSTRETCHED ARM.

13
00:00:43,376 --> 00:00:47,280
BY WATCHING THE PLANETS LIKE THIS COPERNICUS 
WAS ABLE TO CALCULATE THE DISTANCES OF THEIR

14
00:00:47,380 --> 00:00:49,282
ORBITS BACK IN THE FIFTEEN HUNDREDS!

15
00:00:49,382 --> 00:00:51,551
IMAGINE, JUST, FIGURING THAT OUT

16
00:00:51,651 --> 00:00:52,552
WOW.

17
00:00:52,652 --> 00:00:56,652
GO ELONG-- AND KEEP LOOKIN UP!
