Velocity = 67,000 x the square root of 1.944 In the northern hemisphere October means longer nights, and when the clocks change it makes stargazing a possible in the early evening. This sky map from NASA depicts the origin the Eta Aquarid meteor shower in the constellation Aquarius in the night sky. In other words, r = 1 AU and a = 17.8 AU. However, if these meteoroids were to hit Earth’s atmosphere head-on, that would push the velocity up to an incredible 160,130 miles per hour (257,704 km/h) because 93,130 + 67,000 = 160,130.

Often, astronomers like to give distances of solar system objects in terms of astronomical units (AU), which is the sun-Earth distance. The most famous comet of all — Halley’s comet — returns to our inner Solar System every ~76 years. The shower is coming up on the mornings of May 4, 5 and 6, 2020. In the early hours of Wednesday, October 21, 2020, planet Earth will plunge through a trail of dust and debris left in the in the inner Solar System by the most famous comet of them all. Cue a rare “Halloween Hunter’s Blue Moon” on October 31, 2020, which will be best caught at Moonrise. since. Halley is the only known short-period comet that is regularly visible to the naked eye from Earth, and the only naked-eye comet that can appear twice in a human lifetime. Thanks to its short period (just 3.3 years) many amateurs have already seen this comet on multiple apparitions. That’s because it deposits meteoroids in the orbital path of the Earth both on its way in, and on its way out, of the Solar System. There are two meteor showers in October, with the Draconids followed soon after by the Orionid meteor shower, which peaks in the very early hours of Wednesday, October 21, 2020.

As Earth's orbit takes the planet through that cloud each year, bits and pieces collide with our world and burn up in the atmosphere, creating bright streaks. Velocity = 93,130 miles per hour or 25.87 miles per second. The Eta Aquarids meteor shower—known for fast-moving meteors and numbering around 10-20 per hour at its peak—will take place between April 19 and May 28, 2021, and peak on the night of May 5, 2021.

That's what's happening on Tuesday, October 13, essentially placing us between Mars and the Sun. You could see up to 20 meteors per hour if you’re lucky.
