PLANETS IN MAY 2019.

MERCURY will be visible about an hour before sunrise for the first week of May, a few degrees to the lower right of Venus. The moon, as a very thin crescent will be some 6° above Mercury on the morning of May 3.

Mercury is at superior conjunction on the 21st, so too close to the Sun for observation for the last three weeks of May.

VENUS drops further behind Mercury during May and remains a morning object. It will be readily visible fairly low in the morning twilight. The crescent moon will be to the right of and a little lower then Venus on the morning of May 3.

MARS is the one planet visible in the early evening. It sets about 2 hours after the Sun all month, a low object to the northwest as the sky darkens. On the 8th the crescent moon will be 3.5° above Mars

JUPITER will be easily visible to the east in the second half of the evening during May. It is also visible to the north and then west in the morning. The near full moon is just under 2° from Jupiter on the morning of May 21.

SATURN rises early evening by the end of May, so will readily be visible to the east an hour or two later. This month's occultation by the moon is visible from the south Indian Ocean.

URANUS begins to move up into the morning sky during May. It is one degree to the left of Venus on the morning of May 19.

NEPTUNE is also a morning object. It will be about 3° to the lower left of the moon on the morning of June 28, with the moon just past last quarter

PLUTO is about 3° from Saturn all month.

PALLAS rises at 6.45 pm on May 1 when it will be 9° from Arcturus. By the end of May it will rise at 4.40 pm, shortly before sunset.

VESTA will be 3.3° to the left of Venus on the morning of May 2, with the moon some 9° above the two. The following morning the three will form a triangle with the moon 3° below Vesta and to the lower right of Venus. Vesta will rise at 3.45 am on the 31st.
