Moon-Sized Impactor May Explain Venus' Strange Rotation
Venus' unusually slow and retrograde rotation has long perplexed planetary scientists. A new paper, presented at the European Geosciences Union General Assembly in Vienna, suggests a potential explanation. Models developed by the authors indicate that a high-angle, moon-sized, high-velocity impactor likely initiated Venus' distinctive 248-day rotation, a significant event believed to have occurred within the first 50 million years of the planet's formation.
Planetary scientists have long been puzzled by Venus' bizarre and extraordinarily slow retrograde rotation on its axis. The planet's unique rotational pattern, with a day lasting 248 Earth days, differs significantly from most other planets in our solar system.
New research presented at the recent European Geosciences Union General Assembly in Vienna offers a potential explanation. The authors of the paper argue that their models suggest a high-angle, moon-sized, high-velocity impactor was likely responsible for triggering Venus' unusual rotation.
This significant impact event is theorized to have occurred relatively early in the planet's history, specifically within the first 50 million years of Venus' formation. The findings aim to shed light on one of the long-standing mysteries in planetary science regarding Venus' evolution.
According to Phys.org, this theory provides a compelling hypothesis for the planet's distinctive rotational characteristics.
