It is not known for certain whether the asteroid impact that is believed to have led to the extinction of the dinosaurs affected the Earth's orbit. Some scientists have suggested that the impact may have caused a temporary change in the Earth's orbit, but the evidence for this is not conclusive.
It is generally accepted that the asteroid impact, which is thought to have occurred around 66 million years ago, was a catastrophic event that had a major impact on the Earth's climate and environment. The impact is believed to have caused widespread wildfires, tsunamis, and other disasters that likely had a profound effect on the Earth's ecosystems. However, the precise effects of the impact on the Earth's orbit are not well understood and remain a topic of ongoing research.
