The word planet is derived from the Greek word for "wanderer." Unlike the background stars, planets seem to move around the sky, keeping mostly to a narrow track called the ecliptic, the path of the Sun across the stars. Dwarf planets and small solar-system bodies are not so constrained, often moving far above or below the ecliptic.
Object | Location | Description |
---|---|---|
Sun | Libra -> Scorpius -> Ophiuchus |
|
Mercury | Libra | Mercury is a busy planet this month. Inferior conjunction takes place on 8 November but this event is a special one as this nearest planet to the Sun actually transits our star. The last transit of Mercury took place in 2003 and the next one won't happen until 2016. Mercury is visible in darkened skies from mid-month and is best observed from the northern hemisphere as it climbs above the eastern horizon before sunrise. This tiny planet reaches greatest elongation west on 25 November. |
Venus | Libra -> Scorpius -> Ophiuchus |
The "evening star" slowly rises above the western horizon after sunset but will be difficult to spot due to its very low position. It will become a little easier to view (higher in the sky) next month. |
Mars | Virgo -> Libra |
At conjunction last month, Mars stays stubbornly close to the Sun and is difficult if not impossible to view this month. |
Jupiter | Libra | The largest planet in the solar system reaches conjunction on 21 November and is lost in the solar glare this month. It re-emerges as a morning sky object next month. |
Saturn | Leo | This is an excellent time to view Saturn and its rings through a telescope. Quadrature enhances interesting disc and ring shadow interplay and Saturn reaches west quadrature on 17 November. Why not have a look for it after midnight whilst you're watching the Leonids! |
Uranus | Aquarius | Barely visible to the naked eye, this planet sets about two hours after its outer solar system neighbour Neptune. |
Neptune | Capricornus | The most distant planet in the solar system reaches east quadrature on 9 November. Look westwards after sunset for it; this gas giant sets before midnight. |
Constellations are patterns of stars in the sky. The International Astronomical Union (IAU) recognises 88 different constellations. The brightest stars as seen from the Earth are easy to spot but do you know their proper names? With a set of binoculars you can look for fainter objects such as nebulae and galaxies or some of the closest stars to the Sun.
Descriptions of the sky for observers in both the northern and southern hemispheres are available for the following times this month. Subtract one hour from your local time if summer (daylight savings) time is in effect.
