Mars, Saturn and Jupiter will be prominent in the evening sky with the latter low by late evening. Mercury will start June as an easy morning object in the dawn sky. It will brighten during the month but get too close to the Sun to observe towards the end of June.

Venus is at superior conjunction on June 7, it then becomes an evening object but remains too close to the Sun to observe.

MERCURY starts June as a morning object rising more than 2 hours before the Sun on the 1st. With a magnitude 0.9 it will be 10° up an hour before sunrise. Look for Mercury in a direction nearly 30° north of east. The planet is at its greatest elongation 24° west of the Sun on the 5th. During the rest of June Mercury will slip back towards the Sun but also gain in brightness, reaching a magnitude -1.6 on the 30th. But by then it will rise only 30 minutes before the Sun.

On the morning of June 4 a very thin crescent moon will be 6° from Mercury, the moon to the lower right of the planet. An occultation of Mercury by the moon, shortly before midnight NZ time, will only be visible from parts of the southern Atlantic Ocean including South Georgia.

VENUS is close to the Sun all month. Too close for observation. On the first it rises into the morning sky only 7 minutes before the Sun.

The planet is at superior conjunction on the far side of the Sun on June 7. At this conjunction Venus will pass behind the Sun as "seen" from the Earth. In fact the "occultation" of Venus by the Sun lasts from about 11 am on June 6 (June 5, 23hr UT) to 9am on June 8 (June 7, 21 hr UT), that is for some 46 hours. At conjunction Venus will be 108 million km (0.72 au) beyond the Sun

After conjunction Venus will become an evening object. By the end of June it will set only 25 minutes after the Sun.

MARS starts June at magnitude -2.0, the same as Jupiter. But the colours are very different, Mars being distinctly orange. Following conjunction late in May, the Earth will be pulling away from Mars during June. As a result the planet will dim a little, but still be at magnitude -1.6 on the 30th.

During June Mars will be in Libra moving to the west towards alpha Lib and away from Antares and Saturn. The planet is stationary on June 30.

The 90% lit moon will be at its closest to Mars for the month on the evening of the 17th when the two will be a little over 8° apart..

JUPITER will be best placed for viewing early evening as it sets shortly after midnight on the 1st and at 10.42 pm on the 30th. The planet remains in Leo, its position changes little during the month, being stationary on June 10.

The 41% lit moon will be about 5° below Jupiter an hour or so before they set on June 11. They will be considerably closer, while below NZ's horizon, a few hours later.

SATURN is at opposition on June 3, so will be rising close to the time of sunset and setting near the time the Sun rises. At opposition Saturn will be 1.35 billion km from the Earth (9.01 AU) and a further 150 million km from the Sun.

The planet is in Ophiuchus moving slowly to the west a few degrees below Antares, as seen in the evening. With a zero magnitude Saturn is noticeably brighter than Anatares or any other star near it. Mars, brighter still, is 18° from Saturn.

The moon passes Saturn on the 19th but the two will be closest soon after midday. By the time they are visible in the evening the almost full moon will be 5° below Saturn. The latter will be about 22° up to the east.


URANUS is a morning object in Pisces at magnitude 5.9. It rises about 4 hours before the Sun on June 1 and 6 hours earlier on the 30th. The moon passes Uranus twice during June.

On the morning of June 2 at about 7am, the 15% lit crescent moon will be just over 3° from Uranus. The planet will be to the left of the moon and a little higher. It should be easy to spot Uranus using binoculars, there are two stars a little fainter than Uranus between the two.

The moon passes Uranus again on the 29th. This time the two are closest at midday, at 7am they will again be just over 3° apart, with the 38% lit moon above and a little to the left of Uranus..

NEPTUNE rises at midnight on June 1 and nearly 2 hours earlier on the 30th. So the planet is beginning to move into the evening sky, but will still be best placed for viewing in the morning a while before sunrise. The planet, at magnitude 7.9, is in Aquarius.

Neptune is stationary on June 14 after which it will start to move slowly to the west. It will be about half a degree from the 3.7 magnitude star lambda Aqr. The planet will be to the upper right of the star. No stars as bright as Neptune are between the two.

PLUTO at magnitude 14.3 rises early evening during June, less than half an hour after sunset by the end of the month. The planet remains in Sagittarius. It passes the 2.9 magnitude star pi Sgr during June, with the two only 3 arc-minutes apart, one-tenth the diameter of the full moon, on the 25th.


(1) Ceres, magnitude 9.3, is in Cetus during June. It rises at 2.45 am on the 1st and just under an hour earlier by the 31st.

(4) Vesta is a dawn object in Taurus. At the beginning of June it rises half an hour before the Sun, by the end of the month some 95 minutes before the Sun. Mercury passes Vesta during June as the two move east. They are closest on the mornings of June 22 and 23 when Vesta (magnitude 8.4) will be 2° to the upper right of Mercury (magnitude -0.8)
