Jupiter, the Solar System’s largest planet, reaches opposition on the evening of 7 April and lies closest to Earth for 2017 the following night. Don’t miss the 14-day-old Moon passing close by on the night of 10 April too. Here’s our comprehensive guide to what to see on Jupiter and phenomena of its bright moons for the month ahead.
Jupiter is now less than a month from opposition (7 April), so it’s very much open season for the Solar System’s largest planet. If you’re unsure where to find it, the rising 17-day-old waning gibbous Moon passes just two degrees from Jupiter on the UK evening of 14 March. Virgo’s brightest star, first-magnitude Spica, makes it a great binocular triumvirate.
Before sunrise on Thursday 19 January, observers in Western Europe can see an interesting celestial conjunction in the southern sky. At about 6am local time, the waning gibbous Moon, largest planet Jupiter and Spica — the brightest star in the constellation of Virgo — all lie in a line encompassed by the field of view of a typical 7x or 8x binocular.
