A comet first spotted over 90 years ago will result in a meteor shower on Tuesday at about 1 a.m. EDT.

The meteor shower, named the tau Herculids shower, is likely to be visible from a majority of the United States, south-central and eastern Canada, Mexico, Central and South America, and a small slice of West Africa, according to astronomers. It can be best seen in a dark sky. The new moon happens to line up with the shower, providing a dark canvas for the comet.

Tau Herculid particles will encounter the Earth at a velocity of 10 miles per second, which is considered slow by astronomers. Since the faster the meteoroid is the brighter its light appears, this shower may not end up being visible at all.

"NASA has stated that this meteor shower is going to be boom or bust. It's either going to be a fantastic meteor shower where you may get thousands of meteors per hour, or you aren't going to get any. It's going to be one or the other," said Tom Wildoner, Darkside Observatory, according to a report.

Comet 73P/Schwassmann-Wachmann 3, otherwise known as SW 3, was spotted on May 2, 1930, by two German astronomers who serve as its namesake. Later, astronomers noticed that it orbited the sun every 5.4 years, but they occasionally lost sight of SW 3 over the years.

Then, in 1995, SW 3 inexplicably shattered into four pieces under astronomers' observation. Ever since, its fragments have been headed to Earth. At its last appearance in March 2017, astronomers could count 68 fragments.

This comes after the Leonid showers in November of last year. Those showers are expected by astronomers to be seen roughly every 33 years.
