Clara Young

"According to latest calculations of its final trajectory, the asteroid 2020 NA, or most of you like to call it Clara, is projected to impact somewhere in western Europe on October 10, approximately 2:47 pm, Central European Time."

Clara Young is a character played by Rebecca Rittenhouse that is planned to appear in the 2020 Toho disaster film, #JusticeForLove: End of the World, but did not appear in the final cut of the film.

#JusticeForLove: End of the World
An astronomer working at an unspecified observatory, she would discover an unidentified object, which turns out to be an asteroid. After additional observations and calculating its orbit, she realizes that the object is 10-kilometers wide, and is on a collision course with Earth, large enough to trigger an extinction-level event. She informs NASA regarding her discovery, and the object is given the provisional designation "2020 NA" by the MPC.

Following the destruction of Tokyo, Japan from an asteroid impact, she discovers that smaller fragments were responsible, and insists that the world should be informed regarding the threat, but the United States government still refuses her request by assuring the destruction of Tokyo was an isolated incident. Another fragment is later discovered that will hit Northern California, but she is unable to warn the people of the San Francisco Bay Area due to the government prohibiting her from making any public appearances. As the asteroid becomes visible to the naked eye, the United Nations finally reveals the asteroid's existence to the public, and the United States government makes a public apology to her.

She returns on making public appearances on television as the discoverer of the asteroid. After the attempt to deflect the asteroid using ICBMs failed, she publishes the object's final trajectory to NASA, which shows that the asteroid will impact somewhere in western Europe on October 10, 2020. To her dismay, despite years of studying asteroids and its potential threat to Earth, mankind had failed to prevent the incoming catastrophe, and is now about to meet the same fate as the non-avian dinosaurs during the Cretaceous–Paleogene extinction event 66 million years ago.

Trivia

 * Despite all of her scenes being cut in the film, Adam McKay was certainly aware of the film's production, and Rittenhouse's role in the story influenced McKay to include a similar character in his own film, Don't Look Up, with Jennifer Lawrence being cast for the role.
