Galactic Navigation
Degrees Latitude
Look at the Degrees Latitude diagram again. See the large pink circle. If all
objects in outer space were exactly on the circle*, then an object that was at
+10o would always be the same distance from the galactic plane as
would an object that was at -10o. However, this is not the case. None
of the objects in the diagram are exactly on the circle. Some are nearer, and
some are farther.
(*Actually, the yellow circle is just imaginary. It could be
much bigger or much smaller. The circle is there to help the diagram show the
degrees of latitude in galactic coordinates.)
The objects at +10o and -10o are at different distances
from the galactic plane; object 2 is closer to the galactic plane than object 1
is because it is at the same latitude and is closer to the Earth. Try to figure
out where objects 1, 2, 3 and 4 would be on the black and white map.
