The moon is near the planet Saturn tomorrow morning.  More on
planet-watching -- in a moment.

March 11  Saturn and the Moon

The moon, a planet and a star should put on a good show for sky
watchers late Monday night and Tuesday morning.  During the day on
Monday the moon moves past the planet Saturn on the dome of the sky.
By the time our part of the globe is turned in their direction -- the
gibbous moon will still be seen near the planet in the night sky.

Saturn will be the bright object north of the moon late Monday or
before dawn Tuesday.  Nearby will be the red star Antares.  So if
you're up -- and have clear skies -- look southward for the moon,
Saturn and red Antares.

And if you look again late Tuesday night or Wednesday morning, you'll
see the moon has moved eastward on the dome of the sky.  Then it'll be
much closer to the star Antares.  It would be hard to notice -- but
Saturn will have moved WESTWARD on the dome of sky in relation to
Antares.

Saturn has just started retrograding -- drifting westward against the
background stars.  Saturn is farther out from the sun than Earth -- and
moves more slowly around the sun than our planet.  In the race of
planets around the sun -- the Earth is now gaining ground on the inside
track.  It's as though we're in a fast car on the highway.  If you look
out the window as you pass another car, it can appear to be moving
backwards against the more distant landscape.  Likewise, Saturn now
appears to be moving backwards -- or retrograde -- against the stars.
