The Eta Aquarids are named after the radiant point of the meteor shower, from which the meteors appear to the viewer to originate and which aligns with the faint star Eta Aquarid, one of four stars which make up the Water Jar asterism in the northern part of the constellation Aquarius the Water Bearer.
The meteors are viewable in both the Northern and Southern hemispheres in the hours before dawn, though less meteors will fall in the Northern Hemisphere, with an hourly rate of only about 10 meteors. However, viewers may be able to catch a glimpse of 'earthgrazers,' meteors that skim along the upper part of the atmosphere, appearing when the radiant of a meteor shower is near the horizon, spewing meteoroids not down, but horizontally overhead.
Around October 21, the Earth will cross the orbital path of Halley’s Comet again, leading to the Orionids meteor shower, the second of the year to originate from Halley's Comet, whose nucleus sheds ice and rocky dust into space each time it returns to the inner solar system.This video, produced using time-lapse photography, shows the Eta Aquarids meteor shower in 2013.
Halley's Comet, first recorded by astronomers in at least 240 BC, crossed the Earth's orbit in 1986 and is scheduled to visit again in 2061; its current position is beyond the orbit of Neptune.
