THE PLANETS THIS MONTH.
MERCURY.
Mercury is at greatest Western elongation on the 9th and is therefore a morning object. However, the angle of its orbit with respect to the horizon is acute and the apparition is not a good one this month. This TABLE. however will show how you can use Venus, Jupiter, and Saturn as well as the Moon as pointers but you will need a clear, flat horizon such as the sea to have any success. This is the big challenge this month.
VENUS.
Venus is rising three before the sun, and is quite a beacon in the eastern sky and throughout this month and the next Jupiter and Saturn pay close calls, Saturn lying 43′ to the north on the 16th. The stars of Taurus and Orion are in attendance with the Pleiades star cluster lying directly above Venus on the 10th. On the 17th the Moon passes 39′ south of Venus at 09h.
MARS.
Mars is still well placed for observation after last month’s opposition. Later this month Mars halts its retrograde motion and moves est again. On the 30th at 16h the Moon and Mars passes 39′ south of Venus at 09hr.
ASTEROIDS.
- Ceres at opposition on 1st in the constellation of Ophiuchus. However, it cannot be seen with the unaided eye although photographs will reveal its presence.

JUPITER.
Jupiter is starting to recover from last month’s solar conjunction and will quickly become visible in the morning sky, heading towards Venus.
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, lying to the west of Jupiter passes 43′ north of Venus on the 16th.
URANUS and NEPTUNE.
Uranus at Mag 5.7, having overtaken slower moving Neptune some years ago now, heads slowly towards the stars within the constellation of Capricornusas seen from Earth.
Neptune, lies in the constellation of Capricornus and is at opposition this month on the 30th at mag 7.9
Uranus Positions for the 1st July:
R.A. DEC TRANSIT TIME MAG
21h:47m:57s -14°:04':57" 03h:21m 5.7
Neptune Positions for the 1st July:
R.A. DEC TRANSIT TIME MAG
20h:42m:06s -18°:05':19" 02h:15m 7.9
PLUTO.
Pluto can be found in Ophiuchus, roughly between the 4th stars Zeta Ophiuchi and 20 Ophiuchi. The best time to look for the planet is around New Moon. The dates below will be a guide for planning observations.
Positions for July 2001 are when Pluto's elongation angle is greater than 90°. DATE R.A. DEC TRANSIT TIME July 10th 16h:51m:46s -11°:49':41" 22h:50m July 20th 16h:50m:44s -11°:51':35" 22h:10m July 30th 16h:50m:08s -11°:54':09" 21h:30m
Pluto is best seen between July 13th – July 27th
