The Planets in June
Mercury will be difficult to see at any time in June. In the evening Jupiter gets low to set fairly soon after sunset, Mars and Saturn are visible all evening. Venus remains a brilliant morning "star" but gets a little lower during the month.
MERCURY sets some 80 minutes after the Sun at the beginning of June. It will be at magnitude 1.4. 45 minutes after the Sun sets Mercury will be only 4.5Â° above the horizon. With the Sun 8.7Â° below the horizon the sky will be bright in the direction of the planet, making it a very difficult object.
Over the following evenings Mercury will get even lower especially after it is stationary on June 7. This leads up to the planet being at inferior conjunction between the Earth and Sun on the morning of June 20. At conjunction Mercury will be 82.9 million km, 0.554 AU, from the Earth and 0.464 AU from the Sun.
Following conjunction Mercury will become a morning object rising before the Sun. By the end of the month, 45 minutes before sunrise, the planet will be only 4.2Â° up with a magnitude 2.7, so not visible
VENUS, in the morning sky, will rise just over 3 hours before the Sun on the 1st dropping to just over 2 hours before it on the 30th. Thus it will get a little lower, but remain a prominent object to the northeast in the dawn sky.
Towards the end of June, Venus will be in Taurus and move to be between the Pleiades and Aldebaran at the end of the month. On the morning of the 27th the Pleiades and Venus will ruse at the same time, with the star cluster 7Â° to the left of the planet.
On the morning of the 25th a very thin crescent moon, 6% lit, will be 3.5Â° to the right of Venus, with the moon slightly lower.
MARS remains a bright object in the evening sky throughout June. It will lose brightness a little, dimming from magnitude -0.5 to 0.0 during the month. It sets just before 3 am on the 1st and by 1.25 am on the 30th. It is in Virgo, by the end of June just over 6Â° from Spica.
The 73% lit moon will be about 3.5Â° to the right of Mars early in the evening of June 8. During the evening their separation will slowly increase as the moon moves towards Spica. The moon is closer to Spica the following night.
The two asteroids Ceres and Vesta will be near Mars all month, some 12Â° from the Planet on the 1st and 9Â° away on the 30th.
JUPITER gets low in the early evening sky during June. It sets 170 minutes after the Sun on the 1st, half this, 85 minutes later on the 30th. Hence by then it will be very low once the sky begins to darken following sunset.
Jupiter remains in Gemini during June, about 7Â° from Pollux which will be lower than the planet.
The moon passes Jupiter twice during June. On the 1st the crescent moon, 11% lit will be just under 5Â° to the upper left of Jupiter early evening. On the 29th the moon and Jupiter are closest about 1pm. At 6 pm the moon as a very thin crescent only 3% lit, will be again be 5Â° from the planet, and again to its upper left. At 6pm Jupiter will be only 4Â° up as seen from Wellington.
SATURN will be a prominent object throughout the evening. It transits and so is to the north and at its highest a few minutes before 11 pm on the 1st, advancing to 2 hours earlier by the 30th. The planet will be in Libra, between the two brightest stars of the constellation. By the 30th the 3 will almost be in line.
The 90% lit moon will be 5Â° from Saturn on the evening of June 10. They are only half this distance apart before Saturn and moon set about 5am the following morning.
This month's occultation of Saturn by the moon is mostly over the southern Indian Ocean and parts of the Antarctic. Early on the northern edge of the occultation path crosses southern parts of Namibia and South Africa. Towards its end the extreme northern edge touches the southeast corner of Western Australia, with a graze well south of Perth. By then the moon will be very low and close to setting.
OUTER PLANETS Uranus rises shortly before 3 am on June 1st and just after 1 am on the 30th. Thus it remains a morning object. The planet is in Pisces with a magnitude ranging from 5.9 to 5.8 during the month.
Neptune rises 20 minutes before midnight on the 1st and nearly 2 hours earlier by the 30th. The planet is in Aquarius with a magnitude 7.9
BRIGHTER ASTEROIDS: (1) Ceres and (4) Vesta get even closer during June. On the 1st they are about 2Â° apart, by the 30th the separation will drop to only 25', less than the diameter of the full moon. This presents an unusual opportunity to view two asteroids in the same binocular field. Vesta'a magnitude ranges from 6.6 to 7.0 during June, Ceres's 7.8 to 8.4.
The two asteroids are also close to Mars, all three being in Virgo. On the 1st the two asteroids will be some 12Â° to the right of Mars, by the 30th they will about 9Â° to its right. Spica will then be about 6Â° above Mars as seen late evening.

- apogee: Furtherest point in the orbit of a body orbiting the Earth
- declination: 'Latitude' for celestial objects. The distance in degress above (north) or below (south) the celestial equator.
- inferior conjunction: Conjunction where a solar system object is between the Earth and the Sun
- perigee: Nearest point in the orbit of a body orbiting the Earth
