Lab #12: Charting the Milky Way's Center (continued) Page 4 Qf 4
The plane of the galaxy in the polar graph lies across the page's surface, so it depicts a view
from above the disk of stars that constitute the Milky Way. The Earth is at the center of
the graph.
• What do you notice about the plotted points? Are they scattered everywhere on the
graph or are they concentrated in a particular region?
• Are the clusters distributed fairly equally on either side of a particular galactic
longitude? If so, what longitude would you say points in that direction?
Assume that the distribution of globular clusters is roughly uniform in the Milky Way's
halo. Draw a small, distinct circle where you estimate the center of the galaxy would lie.
• How many kiloparsecs separate the Milky Way's center (the circle you drew) from the
Earth's location in the galaxy (the center of the polar graph)?
kpc
-What do you estimate the uncertainty would be in your distance value (For example, five
percent, twenty percent, fifty percent)?
Use reputable Internet sites to find the accepted distance and find the percent difference
between your distance estimate and the actual one.
