Highlights: Venus brilliant in February’s evening sky. Jupiter dominates morning sky.
Welcome to Skymania’s guide to the night sky in February, 2017. You will find a map of the whole visible sky, which can be adjusted for any time and date, plus information on the position of the planets, phases of the Moon, and notable astronomical events to watch out for.

The sky in February 2017
Summary: Venus shines brilliantly in the evening sky, with Mars nearby. Jupiter dominates the morning sky, with Saturn rising later in the night. Asteroid Vesta is still bright enough to spot with binoculars, in Gemini. (If you don’t own an optical aid, we’ve advice on choosing binoculars or a telescope here). An annular eclipse of the Sun is visible from parts of South of America and Southern Africa on February 26.
Venus is still shining brilliantly in the evening sky and is impossible to miss, at magnitude -4.8. That is bright enough to spot with the unaided eye in broad daylight if you know just where to look. The brightness is because the planet is swinging in between Earth and the Sun. Through a small telescope, it will be seen as a crescent. Don’t expect to see any surface details though as the planet is permanently shrouded in cloud. Venus is close to Mars at the start of the month.
Mars is still hanging on in the evening sky, shining like a bright star, but is totally put in the shade by the overpowering brilliance of Venus. The planet is receding on the far side of the Sun now and its brightness fades from magnitude 1.1 to 1.3 during the month.
Jupiter, the biggest planet in the Solar System, is very well placed for is a brilliant planet in the morning sky at the start of the month, rising half an hour or so after midnight. Find it in the constellation of Virgo, not far from its brightest star, Spica. By month’s end, it rises before 11pm. The planet brightens slightly from -2.1 to -2.3, making it the brightest object in the sky after Venus. A small telescope will reveal the planet’s belts and bands as well as the four main moons, known as the Galilean satellites, Io, Europa, Ganymede and Callisto.
On February 11, a penumbral eclipse of the Moon occurs. This eclipse, where the Moon only passes through the lighter outer shadow of the Earth, called the penumbra, is entirely visible from Africa and parts of South America, with the west of that continent seeing the event already underway at moonrise. The Full Moon will appear to be slightly dimmer than usual. None of the eclipse can be seen from Australia and New Zealand. An annular solar eclipse, on February 26, where the Moon is not quite big enough to cover the Sun, will be visible from parts of southern Chile and Argentina before crossing the Atlantic into southern Africa, ending in the Democratic Republic of the Congo. Here is our guide to seeing it.

Comet 45P/Honda–Mrkos–Pajdušáková will become bright enough to see with binoculars at around magnitude 7.5 during the first couple of weeks in February. It passes close to Earth as it moves away from the Sun, and rapidly races across the sky through the constellations of Aquila, Hercules, Corona Borealis and Bootes in a matter of days. Look for it becoming high in the sky in the hours before dawn with the aid of our chart.
A second comet, C2015 V2 Johnson, will become visible in small telescopes in Hercules towards the end of the month, at around magnitude 9.5 as it heads to a closest approach to the Sun in June.
The Moon always makes a great target for a small telescope, which come into view as its phases change. We’ve a guide to where to find 50 of the best lunar features, plus a checklist to download so you can tick them off as you spot them! Don’t have a telescope? Here’s our guide to choosing one.
