    planets THE PLANETS THIS MONTH.

    mercury MERCURY.

    Mercury becomes a favourable object again. Looking to the North of West some 40 minutes after Sunset this elusive planet will be at its best between the 11th and the 26th. With the crescent Moon paying a visit toward the end of that peroid you should stand a good chance of locating the solar systems innermost world.This table describes the apparition as it progresses. Jupiter and Saturn, in their hasty journey towards the Sun, offer further pointers although it has to be said that saturn is pretty unfavourable. Mercury is brighter during the first half of May.

    venus VENUS.


    Venus does a little double take, stopping its motion along the horizon and increasing its altitude slightly. It is quite low down in the morning twilight but it will soon improve.

    mars MARS.


    Mars, rising at midnight at the end of May, is visible for most of the night in southern Ophiuchus. In January its apparent diameter was a mere 5.2" of arc but it now sports a healthy 14-19" disk as it heads towards next months opposition. On the 10th the Moon passes 1.5° north of Mars at 01hrs

    ASTEROIDS.


  • 1 Ceres is in Sagittarius at Mag 8.5 ( Opposition next month).
  • 2 Pallas is at opposition on May 27th at mag 9.2 in Hercules.
  • 7 Iris is at opposition on May 9th at mag 9.6 in Libra.
  • 15 Eunomia is at opposition on May 23rd at mag 9.9 in Lupus.

    JUPITER.


    Jupiter quickly heads towards the Sun in the evening sky and becomes unfavouable.

    Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.

    SATURN.


    Saturn is at solar conjunction on the 25th, thus isunfavourable for observations. It reappears in the morning sky in July.

    URANUS and neptune NEPTUNE.


    Uranus is starting to become favourable among the stars of Capricornus. It shines at Mag 5.8.

     Positions for the 1st May:

                          R.A.                   DEC                    TRANSIT TIME           MAG
                      21h:48m:12s           -14°:01':08"                   07h:23m             5.8

    Bluish Neptune is also in Capricornus at this time,less brigher than Uranus. Both should be seen in dark sky location with clear skies.

     Positions for the 1st May:

                          R.A.                   DEC                    TRANSIT TIME           MAG
                      20h:44m:35s           -17°:55':17"                   06h:20m           7.9

    PLUTO.


    Best time to look for the almost 14 mag planet is around New Moon. The dates below will be a guide for planning observations.

     Positions for May are when pluto's elongation angle is greater than 90°.

    
DATE                      R.A.                   DEC                   TRANSIT TIME

May  11th              16h:57m:53s            -11°:52':23"                 01h:52m

May  21st              16h:56m:53s            -11°:50':28"                 01h:12m

May  31st              16h:55m:50s            -11°:49':04"                 00h:31m

    On June 3rd Pluto at 13.8 Mag reaches opposition in Ophiuchus. It can be found between Zeta Ophiuchi Mag 4 and 20 Ophiuchi mag 4.7. You will need an 8-inch or larger telescope and the best time to see Pluto is when the Moon is not around.
    It is best seen between May 15th - May 29th.
