Read the following question and post your answer to the discussion board.
Respond to at least one of your classmate's posts.
As our home, Earth holds a special place in our collective hearts, and serves as the example on which we base our comparisons to the other terrestrial worlds. We have even named the class after it, as terrestrial means "Earth-like."
Choose one other terrestrial world (Mercury, Venus, Mars, or Earth's moon) and explain which differences (or similarities) you find most fascinating about it, and why. Would you ever want the chance to visit your chosen world?
