Asteroid
Although their location in the asteroid belt excludes them from planet status, the three largest objects, Ceres, Vesta, and Pallas, are intact protoplanets that share many characteristics common to planets, and are atypical compared to the majority of "potato"-shaped asteroids. The fourth largest asteroid, Hygiea, has an undifferentiated interior, like the majority of asteroids. Between them, the four largest asteroids constitute half the mass of the asteroid belt.
Armageddon (1998 film)
In an interview with "Entertainment Weekly", Bay admitted that the film's central premise "that NASA could actually do something in a situation like this" was unrealistic. However, the largest known Potentially Hazardous Asteroid(PHA) is (53319) 1999 JM8 which is actually only 7 km in diameter. Additionally, near the end of the credits, there is a disclaimer stating, "The National Aeronautics and Space Administration's cooperation and assistance does not reflect an endorsement of the contents of the film or the treatment of the characters depicted therein."
