In Ice Age: Collision Course, what object is on a path toward Earth?

In Ice Age: Collision Course, an asteroid is on a path toward Earth.

The film’s main story begins when Scrat’s pursuit of an acorn triggers events in space. His accidental actions set a large asteroid on a collision course with Earth, creating the central threat faced by Manny, Sid, Diego, and their families.

The characters respond by searching for a way to prevent the impact. Their journey combines the franchise’s prehistoric setting with a science-fiction-style disaster plot, while Scrat’s space sequence provides the film’s recurring comic interruptions.

The asteroid storyline is fictional and deliberately exaggerated for animated adventure. It should not be confused with the smaller celestial bodies or space phenomena featured in other science-fiction films. Collision Course uses the asteroid as a clear, singular threat rather than presenting several equally possible causes of danger.
