Part 1. Definition
In this task, a passage will be given and the goal is to generate a question about temporal relations based on that passage. A temporal relation describes the relation between two things with respect to time e.g., something happens/starts/terminates/... immediately/shortly/usually/... before/after/during/... something else.
Your question should include an event, or ask about an event, and should not be a yes/no question.
Part 2. Example
Passage: I submitted the hit. The hit was approved, and then I was paid.
Answer: What happened after I submitted the hit?
Explanation: This is a valid temporal question based on the given paragraph. Events approved and paid have a temporal relation "after" with the event submitted.

Near-earth objects are comets and asteroids that have been nudged by the gravitational pull and may collide with earth.
