The Motion of the Sun
The positions where the Sun reaches its highest and lowest points are called solstices,
Latin for "the Sun stops" as it changes direction.
The Sun is highest in the sky (in the northern hemisphere) when it is at 6 h R.A.
One of the most notable behaviors of planets - retrograde motion.
Planets move relative to the stars, and they do so, generally, moving from west to east in
the sky. (they travel like the Sun from west to east but due to Earths rotatio

An important characteristic of the stars is that they have relatively fixed positions with
respect to each other, i.e. the constellations do not change with time.
The stars do actually move, but this motion is only
