Halley’s Aquarids


Halley’s Comet last visited earth in 1986; far beyond the orbit of Uranus, it won’t be back until 2061. Halley laps the solar system approximately every 76 years – though light years away, it leaves behind a trail of cosmic dust. Twice a year our orbit passes this dust trail  – in May the Aquarid meteors and in October the Orionids.

The Aquarids – named for their origin in the Aquarius constellation – peak tonight and tomorrow. The southern hemisphere has the best seats for this show with over 50 meteors an hour hitting the atmosphere at 66 Km/second. Northern hemisphere viewers can still see show, even though it’s hampered by Aquarius barely rising above the horizon.
