- The Planets:1994
-
- Visibility of Planets:
-
- MERCURY can only be seen low in the east before
- sunrise, or low in the west after sunset (about
- the time of the beginning or end of civil
- twilight). It is visible in the mornings between
- the following approximate dates: February 27 to
- April 22, July 4 to August 5, and October 28 to
- November 27. The planet is brighter at the end of
- each period (the best conditions in northern
- latitudes occur around the first week of November,
- and in southern latitudes from mid-March to early
- April). It is visible in the evenings between the
- following approximate dates: January 18 to
- February 14, May 8 to June 16, August 23 to
- October 15, and December 30 and 31. The planet is
- brighter at the beginning of each period (the best
- conditions in northern latitudes occur during the
- first week of February and, especially in low
- northern latitudes, during the last two weeks of
- May and southern latitudes from the beginning of
- September until towards mid-October).
-
- VENUS is too close to the Sun for observation
- until the end of February when it appears as a
- brilliant object in the evening sky. By late
- October it again becomes too close to the Sun for
- observation until mid-November when it reappears
- in the morning sky. Venus is in conjunction with
- Mercury on November 12.
-
- MARS is too close to the Sun for observation
- until late February when it appears in the morning
- sky in Capricornus. Its westward elongation
- gradually increases as it passes through Aquarius,
- Pisces, Aries, Taurus (passing 5 degrees N. of
- Aldebaran on July 18), Gemini (passing 6 degrees
- S. of Pollux on September 24), Cancer and into Leo
- (passing 2 degrees N. of Regulus on December 8),
- where it can be seen for more than half the night.
- Mars is in conjunction with Mercury on February 27
- and April 4, and with Saturn on March 14.
-
- JUPITER can be seen in the morning sky in Libra
- at the beginning of the year and by the beginning
- of February it can be seen for more than half the
- night. Its westward elongation increases until on
- April 30 it is at opposition when it is visible
- throughout the night. Its eastward elongation then
- gradually decreases as it passes into Virgo in
- late May; in mid-August it passes back into Libra
- where it can be seen in the evening sky until the
- beginning of November when it becomes too close
- to the Sun for observation. It reappears at the
- beginning of December in the morning sky, passing
- into Scorpius in mid-December.
-
- SATURN can be seen in the evening sky from the
- beginning of the year in Aquarius in which
- constellation it remains throughout the year. In
- early February it becomes too close to the Sun for
- observation until early March when it reappears in
- the morning sky. Its westward elongation gradually
- increases until September 1 when it is at
- opposition and is visible throughout the night.
- Its eastward elongation then gradually decreases
- and by early December it can only be seen in the
- evening sky. Saturn is in conjunction with Mercury
- on February 2 and March 24 and with Mars on March
- 14.
-
- URANUS is too close to the Sun for observation
- until early February when it appears in the
- morning sky in Sagittarius, in which constellation
- it remains throughout the year. It is at
- opposition on July 17 when it can be seen
- throughout the night, after which its eastward
- elongation gradually decreases and from mid-
- October it can only be seen in the evening sky
- until late December when it again becomes too
- close to the Sun for observation.
-
- NEPTUNE is too close to the Sun for observation
- until the beginning of February when it appears in
- the morning sky in Sagittarius, in which
- constellation it remains throughout the year. It
- is at opposition on July 14 when it can be seen
- throughout the night, after which its eastward
- elongation gradually decreases and from mid-
- October it can only be seen in the evening sky
- until late December when it again becomes too
- close to the Sun for observation.
-
- DO NOT CONFUSE (1) Mars with Mercury around the
- beginning of March when Mars is the brighter
- object. The reddish tint of Mars should assist in
- its identification. (2) Saturn with Mars from
- around mid-March, when Saturn is the brighter
- object. (3) Mercury with Saturn in early February
- and late March and with Mars at the end of March
- and early April; on all occasions Mercury is the
- brighter object. (4) Venus with Mercury mid-
- November when Venus is the brighter object.
