Venus (page 2)

based on 3 ratings
Author: Janice VanCleave

For Further Investigation

Sometimes Venus is seen above the western horizon in the evening and is called the "evening star." Do Venus's phases wane (decrease in size) when it moves from superior to inferior conjunction? A project question might be, What are the phases of Venus during one orbit?

Clues for Your Investigation

  1. Repeat the investigation, moving the ball in a complete counterclockwise circle around the light.
  2. Make note of the visible lighted side of the ball as it moves around the light. Diagram the different phases as Venus moves from inferior to superior conjunction, and then from superior to inferior conjunction.
