On the 1st the Moon will be at Perigee – its closest approach to Earth in 2000 at a distance of 337,362km. On the 4th the Earth is at aphelion – the furthest distance from the Sun in its orbit – at a distance of 1.016742 Astronomical Units (1AU = 149.6km).
THE PLANETS THIS MONTH.
MERCURY.
Mercury is at inferior conjunction on the 6th but starts a morning apparition on the 24th, the details of which can be found from this TABLE.
VENUS.
Venus is starting to recover from last month’s encounter with the Sun but it will not be for a few months when it will travel far enough away from the Sun to be easily visible.
MARS.
Mars is in conjunction with the Sun on the 1st.
MARSWATCH – latest observations of the red planet.
ASTEROIDS.
- Vesta at opposition on 16th between Capricornus and Sagittarius and lies to the right of the Uranus and Neptune, (see below), close to M75 on July 1st. At just naked eye it can be seen under good clear skies.

JUPITER.
Jupiter’s apparent diameter increases as it moves away from May’s Solar conjunction. At the start of the month the planet will appear 34.3 seconds of arc across whilst at the end of the month, when Jupiter is a little better placed in the morning sky (in the constellation of Taurus), it will be 36.7″ across. On the 26th (at 21h) Jupiter is 4.5° North of the crescent Moon.
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, like Jupiter is still recovering from solar conjunction in May and it will not be until the end of the month when these two planets will be favourably placed for anyone getting up to observe in the early hours of the morning. On the 26th (at 11h) Saturn is 3° North of the Moon.
URANUS and NEPTUNE.
Uranus at Mag 5.7, having overtaken slower moving Neptune some years ago now, heads slowly through the constellation of Capricornus
Neptune, like Uranus, lies in the constellation of Capricornus and is at opposition this month on the 27th at mag 7.9
Uranus Positions for the 1st July: R.A. DEC TRANSIT TIME MAG 21h:31m:47s -15°:24':17" 03h:06m 5.7
Neptune Positions for the 1st July R.A. DEC TRANSIT TIME MAG 20h:32m:48s -18°:35':31" 02h:07m 7.9
PLUTO.
Pluto can be found inOphiuchus, 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 are when pluto's elongation angle is greater than 90°. DATE R.A. DEC TRANSIT TIME July 9th 16h:42m:29s -10°:57':51" 22h:42m July 19th 16h:41m:44s -10°:59':47" 22h:02m July 29th 16h:41m:08s -11°:02':29" 21h:22m
Pluto is best seen between June 25th – July 8th and July 24th – August 5th.
