THE PLANETS THIS MONTH.
Mercury ends the rather poor evening apparition which started last month and swiftly heads towards next month’s inferior conjunction.
Venus, rising at 03h:00m in the middle of the month, passes very close to two stars at the feet of Gemini and close to another open star cluster (remember Venus passing the Pleiades last month?). On the 21st Venus lies 1°.5 south of M35 and between the 22nd and 24th passes 17′ north of eta and mu Geminorum. After this month Venus starts to head back towards the Sun.
Mars also lies in Gemini and also passes by eta and mu Geminorum, on the 11th and 14th respectively. On the 9th Mars passes just south of M35 but lies a mere 15° away from the Sun. It will be a couple of months before the red planet really starts to show again in the morning sky.
MARSWATCH – latest observations of the red planet.
- Iris is at opposition on July 20th in Sagittarius Mag 8.9
- Pallas is stationary in Pisces on July 26th at Mag 10.0
- For More information on Asteroids Click Here.
Jupiter is approaching opposition and is showing a disk with an apparent diameter of 46″ by the end of the month. Compare this with a measly 33″ at the start of the year and you will see that it is time to get the telescopes out!
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 is also starting to become better placed for observation, rising before midnight at the end of July.
URANUS and NEPTUNE.
Uranus is at opposition next month and owners of telescopes maybe able to see a tiny disk using a high magnification. Uranus is bright enough to be visible in binoculars.
Neptune is much fainter than Uranus and is more of a challenge to locate and observe. It is at opposition on the 23rd.
Uranus Positions for the 1st July: R.A. DEC TRANSIT TIME MAG 20h:58m:37s -17°:50':20" 03h:32m 5.7 Neptune Positions for the 1st July: R.A. DEC TRANSIT TIME MAG 20h:14m:07s -19°:30':24" 02h:48m 7.9
Pluto can be found on the border of Ophiuchus and Scorpius, above and to the right of the mag 2.6 star Zeta Scorpii. The best time to look for the planet is around New Moon. The dates below will be a guide for planning observations.
Positions for June are when pluto's elongation angle is greater than 90°. DATE R.A. DEC TRANSIT TIME July 10th 16h:21m:01s -09°:03':20" 22h:21m July 20th 16h:20m:20s -09°:05':44" 21h:41m July 30th 16h:19m:50s -09°:08':49" 21h:02m
Pluto is best seen between July 16th – 23rd.
