The video discusses the Dawn spacecraft's mission to the asteroid belt, focusing on its encounter with Ceres, the largest celestial body in the belt. Dawn captured images of Ceres from a distance of 1.2 million kilometers. Scientists discovered water vapor erupting from Ceres, possibly from ice geysers on its surface.

How does the distance from Ceres to Earth compare to the distance from Earth to the moon?

What are the features on Ceres that may emit water vapor?
