- This Week January 3 through January 9 - A PASSEL OF PLANETS
- ___________________________________________________________
-
- Planets * Mercury is in superior conjunction (behind the sun) on the
- 23rd and so is too close to the sun to be seen this month.
-
- * Venus is the bright evening star in the southwest.
-
- * Mars rises at sunset in Gemini and is visible all night.
-
- * Jupiter rises around midnight in the constellation Virgo.
-
- * Saturn is very low in the western evening sky. At month's
- end, it lies too near the sun to be seen.

- Events 3 The planet Mars is nearest Earth, 94 million km, (58,
- million miles).
-
- 3 Earth is at perihelion--closest to the sun--147,162,802 km
- (91,445,226 mi).
-
- 3 The Quadrantid meteor shower (active between January 1-5)
- peaks this morning before dawn.
-
- 7 Mars is at opposition. It is opposite the sun in the sky,
- rising at sunset, overhead at midnight, and setting at
- sunrise.
-
- 8 Full moon, called the Old Moon or Moon after Yule.
- ___________________________________________________________
-
- The January January opens with three planets in the evening sky: Saturn,
- Planets low in the west (and soon to disappear behind the sun),
- Mars, rising in the east at sunset, and of course Venus.
- Little Mercury is currently behind the sun and won't
- reappear until the latter part of February low in the west
- after sunset.
-
- You can't miss Venus. It's the bright white beacon in the
- southwest. Venus looks like a distant jet plane with its
- landing lights on. It is so bright that it looks closer
- than it is, which prompts some people to mistake the planet
- for a UFO. In dark skies, Venus will even cast a shadow,
- especially on snow or a light-colored background. The only
- two celestial objects brighter than Venus are the moon and
- the sun.
-
- Nearby, the planet Saturn is putting in its farewell
- performance before slipping behind the sun February 9.
- Already it is approaching too near the sun in the sky to be
- seen for long after sunset. Take a last look early in the
- month, for by the end of January, Saturn will be out of
- sight. We'll then have to wait until late April to see
- Saturn again, this time in the morning sky.
-
- The planet Mars is the bright red "star" in the east. It
- lies near the bright stars Castor and Pollux in Gemini. On
- the 3rd, Mars lies nearly opposite the sun as seen from
- Earth (it is exactly opposite on the 7th). At this time,
- the planet is brightest and is nearest to Earth for this
- orbit. These circumstances make it a good time to study the
- planet in the telescope. If you have a small telescope, put
- in a medium-power eyepiece (with a focal length around 16mm
- or 12mm) and see if you can see the dark "continental"
- features on the disk. These are real surface features, by
- the way--not clouds or shadows, as with Jupiter or Saturn.
- The most prominent feature will be a bright spot at one
- pole. This is Mars's northern polar cap. Since springtime
- began on Mars just this past November, the polar cap is
- just beginning to shrink, so it should remain easily visible
- in small telescopes over the next couple of months.
-
- The largest planet in our solar system makes its appearance
- in the early morning sky this month. If you have a fairly
- flat view to the east, clear of trees, buildings and other
- obstructions, look for Jupiter to peek above the horizon
- around midnight. (You may have to wait until around one AM
- for the planet to clear the cluttered horizon.) Jupiter
- lies near the bright star Spica in Virgo, but it is much
- brighter than this star. In fact, over the next two months,
- Jupiter will grow even brighter as Earth swings nearer the
- planet in our orbit around the sun.

- FINAL ISSUE As most of you know by know Jeff Kanipe decide to
- UPDATE discontinue SKYWATCH. However, he has received many
- personal messages from his electronic readership.
- Jeff is still mulling it over ... however, he is
- amazed at how widespread and caring the SKYWATCH
- readership has become over the last year (in the
- online world).
-
- So, keep those electronic cards and letters coming.
- I'm hoping to get an answer from Jeff within the
- next couple of weeks.
