Trivia: What astronomical feature is between Mars and the fifth planet, Jupiter?
Asteroid belt
Kuiper belt
Oort cloud
Goldilocks zone
Correct Answer: Asteroid belt
So why is this answer correct? : Between Mars and Jupiter lies anywhere from 1.1 million to 1.9 million asteroids at least 0.6 miles (1 kilometer) in size. For a time, scientists worried spacecraft couldn’t escape this “asteroid belt,” but NASA’s Pioneer 10 proved them wrong on February 15, 1973, when it became the first spacecraft to travel through the belt during its visit to Jupiter and beyond.
