THE PLANETS in JUNE 2021
MERCURY is at inferior conjunction between the Earth and Sun on June 11. At conjunction the planet will be just over 3° south of the Sun.
Before conjunction as an evening object Mercury will be too low for observation. Following conjunction it is a morning object rising nearly 100 minutes before the Sun by June 30. It will then be briefly visible, very low, an hour before sunrise at 6.45 am. the planet will be just over 6° above the horizon In a direction some 30° to the north of east.
VENUS is an evening object and moves further out from the Sun during June. It will be visible low to the northwest shortly after sunset getting a little higher as the month progresses. By June 30 it will be some 8° above the horizon at 6pm, an but obvious object in the northwest sky.
On June 12, at about 5.45 pm, when the Sun is about 9° below the horizon, Venus will be only 5° up, the moon as a very thin crescent may be seen even lower, some 2.5° below the planet.
MARS is also a low early evening object in June, setting about 3 hours after the Sun on June 1 and about 20 minutes less on the 30th. Mars moves across the Beehive star cluster (M44) on the 23rd and 24th . As seen from NZ, the planet is closest to the centre of the cluster on the latter date.
The crescent moon will be just over 5° to the right of Mars early evening on June 14.
JUPITER will be a reasonably placed, late evening object by the end of June but, especially early in the month, remains best observed as a morning object. It is stationary on June 21.
The moon passes Jupiter twice in June. At midnight on June 1/2 the moon, near last quarter, will be 4° to the right of Jupiter. Then on the morning of June 29, the moon will again be 4° from Jupiter. The two are closest a little after sunrise.
SATURN rises about 90 minutes before Jupiter, so is becoming well placed for viewing in the late evening sky.
Saturn is a little under 4° to the left of the moon on the 27th. The two are closest late evening.
URANUS and NEPTUNE move further up into the morning sky during June, Neptune being the higher. The moon passes the two planets during daylight hours on the 7th and 4th respectively.
PLUTO, still in Sagittarius, rises fairly early evening by the end of the month.
