PLANETS in OCTOBER 2019

MERCURY and VENUS are evening objects, by the 31st they set about 5 minutes apart. Mercury is at its greatest elongation, 25° east of the Sun on the 20th. Subsequently its easterly motion slows allowing Venus to catch up with it. The two planets are 2.6° apart on the 31st. Mercury will be to the left of the brighter planet and slightly higher. The two will be rather low, about 9° above the horizon at 8.50 pm.

On the 30th, the crescent moon, only 6% lit, will be about 9° to the upper right of the planets.

JUPITER is also an evening planet. On the 31st it sets 2 hours after Venus. Earlier that evening the moon is about 5° below Jupiter. The moon is also a few degrees from Jupiter on the evenings of October 3 and 4.

SATURN is an evening object setting after midnight. This month's lunar occultation on the 6th is visible from parts of southern Africa and the south-eastern Atlantic Ocean.

PLUTO, like Saturn, is in Sagittarius, the two planets are 5.5° apart at the end of the month.

MARS is a nominal morning object but, even by the end of the month, rises only 45 minutes before the Sun.

URANUS is at opposition on the 28th, so becomes observable all night.

NEPTUNE is in Aquarius well placed for viewing in the evening.

VESTA brightens in Taurus and is best seen as a morning object, although it will rise a little before 9pm by the 30th.

METIS is at opposition on the 26th with a magnitude 8.6 making it the second brightest asteroid. It crosses from Cetus to Pisces on the 26th.
