Harvest Moon meets Mars tonight + other stuff in the October night sky

from https://www.forbes.com/sites/jamiecartereurope/2020/10/01/your-stargazin...

Here’s exactly what you need to know about when, where and how to catch October 2020’s stargazing highlights:

1. Draconids meteor shower

When: Anytime after dark on Wednesday, October 7, 2020

Where to look: all-sky

Most meteor showers are at their best around midnight when the viewer is firmly on the night-side of the planet. Not so the Draconids meteor shower, which peaks tonight and is best seen right after dark.

The calling card of a short-period comet called 21P/Giacobini-Zinner, which was last in the Solar System in 2018, its dust and debris will create around 10 “shooting stars” per hour as it collides with atmosphere.

That makes it a great opportunity to go stargazing as soon as it gets dark with the likelihood of at least a few easily visible “shooting stars.”

As the Earth orbits through a cloud of cometary dust it creates a spectacular display of celestial ... [+]

2. Mars at Opposition

When: Anytime after dark this month (but especially on Tuesday, October 13, 2020)

Where to look: Mars will rise in the east, shine all night long in the south and set in the west

Every 26 months Earth and Mars get close. That's because Mars has an orbital period of 687 days while Earth’s year lasts 365 days. Occasionally, Earth catches up on Mars. That's what's happening on Tuesday, October 13, essentially placing us between Mars and the Sun. Consequently, not only is Mars larger in the night sky from our point of view, but it’s 100% illuminated by the Sun—much like the Moon is during a full Moon. So as well as being at its biggest, it's also at its brightest. Not surprisingly, this is the best night to view it, though in practice anytime this month is a good time. Technically speaking, Mars will be bigger and brighter than at any time since 2003.

So get outside this week and watch Mars rising in the east at dusk, and setting in the west at dawn. It’s looking fabulous right now after dark—and unmistakably red.

The Moon will be 1% alongside the bright planet Venus. 

3. A delicate crescent Moon and Venus

When: an hour before sunrise on Wednesday, October 14, 2020

Where to look: east

Getting up early to go planet-hunting and Moon-gazing isn't everyone's idea of fun, but if you are an early-riser it's worth looking due east this morning to see an incredibly bright planet Venus very close to a delicate crescent Moon.

Our waning satellite will be merely 1% illuminated while a 76%-lit Venus will be shining at a majestic -4.0 magnitude.

4. Orionids meteor shower (caused by Halley’s Comet)

When: Very early hours of Wednesday, October 21, 2020

Where to look: all-sky

There are two meteor showers in October, with the Draconids followed soon after by the Orionid meteor shower, which peaks in the very early hours of Wednesday, October 21, 2020.

The result of debris left in the Solar System by Halley’s Comet, expect to see about 10 and 20 “shooting stars” per hour. Give your eyes about 30 minutes to get dark-adapted.

A 45%-lit Moon will form a triangle with bright Jupiter and dim Saturn. 

5. A triangle of Jupiter, Saturn and the Moon

When: After dark on Thursday, October 22, 2020.

Where to look: southwest

Tonight there’s a mighty celestial triangle on show as the bright planet Jupiter teams-up with a 45%-lit young Moon and dimmer Saturn in the south.

Your best time to look is right after darkness falls, before the trio set together in the southwest.

How and when to see a bright planet Mars and an near-full Moon. 

6. An almost full Moon and Mars

When: Thursday, October 29, 2020

Where to look: east

Look any time of night tonight and through the early hours of Friday to see a an almost full Moon close to Mars. The red planet, though now slightly past its bright opposition, will still be shining at a super-bright magnitude -2.2.

Look left to see the beautiful Pleiades star cluster, a sure sign that winter is coming.

7. ‘Halloween Hunter’s Blue Moon’

When: moonrise where you are on October 31, 2020

Where to look: east

No, it’s not going to look blue. As the second full Moon of the month after the “Harvest Moon” on October 1, 2020, tonight’s “Hunter’s Moon” on Halloween will also be known as a “Blue Moon.”

There’s nothing specifically different to see compared to any other full Moon. Just be sure to catch it at Moonrise—in the east at dusk—to fully appreciate the beautiful orangey hues of a rising full Moon.

As a bonus, the rise of the “Halloween Hunter’s Blue Moon” also signifies the middle of the season of fall/autumn. We’re already halfway to the winter solstice ...

Wishing you clear skies and wide eyes.
