FAMILY STARGAZING - ALL MONTH

There’s a chance that comet 46P/Wirtanen will be a naked-eye object throughout December. If it is, then its favourable position makes it a great target for youngsters to look for. The comet passes closest to Earth on 18 December but a bright Moon will interfere with the view at this time. The best periods to look for it will be at the beginning and end of the month (see page 52). The unpredictable nature of comets means that it is probably a good idea to have binoculars on hand, just in case it fails to become bright enough to be seen with the naked eye. www.bbc.co.uk/cbeebies/shows/stargazing
