The night sky in October 2027

5 sky events this month
  • 1 Fri The Moon passes Mercury, about 1.6° apart · around 11:33 PM
    The Moon moves about its own width across the stars every hour, so it passes each planet about once a month. The gap is as seen from Earth's centre; from where you stand it can differ by up to a degree. In the west after sunset.
  • 15 Fri Full Moon · around 01:40 PM
    The Moon is opposite the Sun, so its whole face is lit. It rises around sunset and is up all night.
  • 18 Mon Saturn at opposition: brightest of the year, up all night
    Earth passes between the Sun and Saturn, so Saturn sits opposite the Sun in our sky: it rises at sunset, is up all night and is near its closest to us for the year.
  • 22 Fri Orionid meteor shower peaks (about 20 an hour in ideal skies)
    Dust shed by Halley's Comet burns up high in our air. The meteors seem to fly out of one point, the radiant. Best after midnight, far from city lights; the Moon is 58% lit that night.
  • 29 Fri New Moon · around 01:45 PM
    The Moon is on the Sun's side of the sky and can't be seen. The nights around it are the darkest of the month, the best for the Milky Way and faint meteors.
