The night sky in May 2027

What happens in the sky in May 2027, worked out from orbital data. Open the calendar to see each event in 3D. Times in UTC.

7 sky events this month
  • 6 Thu New Moon · around 10:49 AM
    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.
  • 6 Thu Eta Aquariid meteor shower peaks (about 50 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 0% lit that night.
  • 7 Fri Venus and Saturn meet, 0.6° apart · around 09:04 PM
    Seen from Earth the two planets line up in the sky, though in space they are hundreds of millions of kilometres apart. In the east before sunrise.
  • 12 Wed The Moon passes Jupiter, about 1.2° apart · around 09:49 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.
  • 13 Thu The Moon passes Mars, about 2.9° apart · around 05:07 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.
  • 20 Thu Full Moon · around 11:17 AM
    The Moon is opposite the Sun, so its whole face is lit. It rises around sunset and is up all night.
  • 28 Fri Mercury at greatest eastern elongation: best after sunset
    Mercury is as far from the Sun in our sky as it gets this time, 23°. Look low in the west soon after sunset.
