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
Phases of the Moon
The Moon shines by reflected light
Like the planets, the Moon also follows a path close to the ecliptic across the night sky.
On the Internet, you can use John Walkers Earth and Moon viewer site, to see how the Moon
would look now both

When the Moon moves into the Earths shadow,
a lunar eclipse occurs. Can only occur during Full Moon.

while it is within the Earths shadow.
