The nation will see a total lunar eclipse early on Tuesday, which is election day. According to EarthSky.org, this is the first total lunar eclipse to occur on Election Day in American history.

The next Election Day lunar eclipse won't take place until November 8, 2394, which is 372 years from now.

According to NASA, the next complete lunar eclipse that will be observed in the United States won't occur until March 2025.

According to NASA, a total lunar eclipse happens when the moon and sun are exactly on opposite sides of the planet.

When this happens, Earth blocks the sunlight that normally reaches the moon. Instead of that sunlight hitting the moon’s surface, Earth's shadow falls on it.

If the sky is clear, lunar eclipses may be seen from everywhere on the night side of Earth, according to TimeandDate.com.

While the moon will rise or set during the eclipse in certain locations, some locations won't be able to see the complete event.

According to EarthSky's Bruce McClure, if you live in the U.S., or elsewhere in North America, you can see the eclipse in the wee hours before sunrise Tuesday.

In Washington, D.C., for example, the full eclipse will begin at 5:16 a.m. EST and end at 6:41 a.m. EST.
