DESCRIPTION
First, a few orders of business…. Experiment #6: The Orbit of Mercury. “A Dead, Inert World”. Greatest Eastern and Western Elongations. Times when Mercury has greatest angular separation from the Sun in the sky Rises/sets ~2 hours before/after the Sun, so we can actually see Mercury!. - PowerPoint PPT PresentationTRANSCRIPT

EXPERIMENT #6: THE ORBIT OF
MERCURY

“A Dead, Inert World”
![Page 4: First, a few orders of business…](https://reader036.vdocuments.us/reader036/viewer/2022081604/5681620d550346895dd2382f/html5/thumbnails/4.jpg)
Greatest Eastern and Western Elongations
Times when Mercury has greatest angular separation from the Sun in the sky
Rises/sets ~2 hours before/after the Sun, so we can actually see Mercury!

Why Do We Care? Can’t generally tell where interior planets
are hanging out… There is a contrast problem!
Where do you think those numbers in your textbook came from?
Let’s figure out the orbit of Mercury!!

What This Looks Like in the Sky

What This Looks Like to God

Western Elongation: to the RIGHT of the Sun
Eastern Elongation: to the LEFT of the Sun

On To Business… You will plot table 6.1 on the Elongations of
Mercury, thus tracing its orbit
Remember Earth moved around Sun (about 1 degree per day) while these measurements were taken, so swing your protractor around to match this rotation
Hint: Label your points

WAYS TO LOSE ALL 28 POINTS
FOR THE PLOT TURNING IN A SLOPPY PLOT, INCLUDING:
DRAWING LINES USING PEN INSTEAD OF PENCIL NOT DRAWING STRAIGHT LINES
GETTING THE POINTS WE PLOT TOGETHER WRONG CONFUSING EASTERN AND WESTERN
ELONGATIONS
