Question

Quizplus · Accepted Answer

The flow of solar wind past the comet's head is responsible for aligning the ion tail in space. As solar wind passes over the comet's head, it ionizes the gas in the comet's coma and creates a plasma tail. The solar wind then pushes this plasma tail away from the Sun in a straight line, creating the characteristic curved shape of the comet's ion tail.
