The meteors arrive as hunks of dust from Halley's Comet crashes into the planet's upper atmosphere, with around half of the quick-moving meteors leaving a persistent, visible trail glowing in the sky.
How to watch the Eta Aquarid meteor shower
The shower is best viewed from the Southern Hemisphere, though it's still visible in the Northern Hemisphere. In the United States, the further south you're watching, the better you'll see the remnants of Halley while the comet itself is just outside the orbit of Neptune, according to EarthSky. Its 75-year orbit is the second longest of comets that produce meteor showers here on Earth.
This year, a moon just past full will wash out many of the meteors, which is why you'll get your best viewing opportunity just before dawn. It's not the year's most active meteor shower, but it's still an impressive sight and the arrival of spring makes it a good time to catch one of this year's handful of significant meteor showers.
