Questions and Answers
1.
What Planet is closest to the sun?
A.
Earth
B.
Mercury
C.
Jupiter
Correct Answer
B. Mercury
Explanation Mercury is the closest planet to the sun. It orbits the sun at an average distance of about 36 million miles, which is much closer than Earth's average distance of about 93 million miles. This proximity to the sun also means that Mercury has a shorter year, completing one orbit in just 88 Earth days. Additionally, Mercury has a very thin atmosphere and extreme temperature variations, ranging from extremely hot during the day to extremely cold at night.

Pluto is No Longer a Planet
A.
True
B.
False
Correct Answer
A. True
Explanation Pluto is no longer considered a planet because of a reclassification by the International Astronomical Union (IAU) in 2006. According to the new definition, a planet must meet three criteria: it must orbit the Sun, it must be spherical in shape, and it must have cleared its orbit of other debris. While Pluto orbits the Sun and is spherical, it has not cleared its orbit, as it shares its path with other objects in the Kuiper Belt. Therefore, it is now classified as a "dwarf planet" rather than a full-fledged planet.
