The planets Venus and Saturn make a welcome re-appearance this month, out to the east in the morning sky. You won’t miss Venus—it’s the biggest and brightest light in sky (after the Sun and Moon, of course). Saturn will be to the north of Venus.
Mars is still in the western sky, low on the horizon after sunset and getting lower with each passing day. Mercury is doing the opposite—it is low on the western horizon after sunset but rising higher each night. It will appear close to Mars in the second half of the month.
The giant planet Jupiter is high and bright in the northern sky during November evenings. If you have a telescope and know exactly where to look, you’ll be able to spot the seventh planet, Uranus, nearby to Jupiter. Unfortunately, for most observers it is too dim to be seen with the naked eye.
The Leonid meteor shower will make its once-a-year appearance again this month, with the possibility of meteors being seen over about a one-week span in the middle of the month. The best date to try and see them will the 18th.
Except where indicated, all of the phenomena described here can be seen with just the unaided eye.
Dates and times shown here are for the Australian Eastern Daylight Time zone, and sky directions are from the point of view of an observer in the Southern Hemisphere.
The Moon will be at perigee today, which is the closest point in its orbit around the Earth. The distance between Earth and Moon will be 364,189 kilometres.
It’s New Moon today.
The thin crescent Moon will appear close to Mercury. You might have difficulty seeing them if there are buildings, trees, hills etc in the way. Assuming you do have a clear horizon, you might even need a pair of binoculars to spot them, as they’ll be very low on the western horizon.
Watch for the Moon next to Mars.
It’s First Quarter Moon today, which is halfway between New Moon and Full Moon. And take a look into the western sky after sunset, and low down near the horizon you’ll see Mars next to the red supergiant stars Antares in the constellation Scorpius. Compare the colour and brightness of Mars and Antares—Antares means “rival of Mars”.
The Moon will be at apogee today, which is the farthest point in its orbit around the Earth. The distance between Earth and Moon will be 404,634 kilometres.
Watch for the Moon near to the giant planet Jupiter tonight, high in the northern half of the sky.
There’ll be an interesting grouping low in the western sky tonight after sunset, with Mercury sitting between Mars and Antares.
The early hours of this morning will probably be your best bet to see some of the Leonid meteor shower meteors. You’ll have to be an early riser, as the best time to see them will be after 4:00am. Look to the north-east, about halfway up from the horizon. From a very dark location, you might expect to see about 20 meteors per hour. If you live in a light-polluted town or city, you can expect to see fewer.
Leonid meteors are pieces of tiny dust and debris left in the trail of a comet called Tempel-Tuttle (after its two discoverers). Floating through space, they run into Earth’s atmosphere at a huge speed (around 70 kilometres per second!), so it’s no wonder they put on a light show as they disintegrate in the upper atmosphere.
Watch for Mars and Mercury near to each other tonight, low down on the western horizon after sunset.
It’s Full Moon today. Have a look and see if you can see a faint star cluster near to the Moon. This is the Pleiades, or Seven Sisters, a pretty grouping of stars in the constellation Taurus.
It’s Last Quarter Moon today, which is halfway between Full Moon and New Moon. Take a look at the Moon, and nearby you’ll see a fairly bright, bluish-coloured star. This is Regulus, the brightest star in the constellation Leo.
