The Fox drama is heading into its series finale with an asteroid hitting Austin, which may sound like something you’d only see in a screenplay — but was actually inspired by a real-life meteor that hit Russia in 2013.

“We based this on a meteor that hit Siberia,” 9-1-1: Lone Star co-showrunner Rashad Raisani tells Entertainment Weekly. “It was roughly the size of the Eiffel Tower, and if it had maintained its integrity when it came into the atmosphere, it would’ve eliminated Northern Europe. But fortunately, the thing broke up in the atmosphere. But it still ended up raining debris and shockwaves and shattered windows even 60 miles away.”

The event Raisani describes is known as the Chelyabinsk meteor, which began as an asteroid that entered Earth’s atmosphere on Feb. 13, 2013, at approximately 60 ft. in diameter and weighing 10,000 tons, according to the American Association for the Advancement of Science.

Thankfully, as Raisani describes, the asteroid fragmented into many meteors. Though, terrifyingly — because of its source direction’s proximity to the sun — scientists had not predicted the asteroid’s potential entrance into our atmosphere… so let that fuel your nightmares tonight.

The Chelyabinsk meteor got its name because it made impact just 25 miles from the Russian city of Chelyabinsk. While no one was directly injured by the impact, the resulting shockwave damaged around 7,200 buildings and injured approximately 1,500 people, “almost all by flying glass,” Mark Boslough, a physicist at Sandia National Laboratories in New Mexico, told Space.com a few months after the incident. (He advises that if you’re ever facing a nearby meteor impact, the most important thing is to stay away from windows.)

The 2013 event was the largest of its kind since the 1908 Tunguska event flattened an estimated 80 million trees in Siberia and eye witnesses reportedly stated it killed up to three people.

So what will happen with Lone Star‘s meteor? Monday’s penultimate episode began with a flash-forward of Owen (Rob Lowe) injured and slowly making his way through a smoke-filled facility. “Shut down reactor immediately,” a disarmingly calm robotic voice relays from speakers overhead as Owen attempts to find a button that will (hopefully) stop a possible nuclear meltdown.

“This could be the event where maybe somebody on the team doesn’t make it,” Lowe teases to EW as Lone Star barrels toward next week’s series finale. “Everything is on the table.”
