154
Correct Answer
C. 1930Explanation
Pluto was discovered in 1930. This was the year when astronomer Clyde Tombaugh first observed the celestial body while working at the Lowell Observatory in Arizona. After several months of studying photographs, Tombaugh identified Pluto as the ninth planet in our solar system. However, in 2006, the International Astronomical Union redefined the definition of a planet, and Pluto was reclassified as a "dwarf planet."Rate this question:

Correct Answer
A. 2006Explanation
Pluto was demoted as a planet in 2006. This decision was made by the International Astronomical Union (IAU) during their General Assembly. The IAU redefined the criteria for what qualifies as a planet, and Pluto no longer met the new definition. It was reclassified as a "dwarf planet" instead. This decision was controversial and sparked debates among scientists and the general public.Rate this question:

Who discovered Pluto?
- A.
Paul Lopez
- B.
Clyde Tombaugh
- C.
Percival Lowell
Correct Answer
B. Clyde TombaughExplanation
Clyde Tombaugh is the correct answer because he was the American astronomer who discovered Pluto in 1930. He made this discovery while working at the Lowell Observatory in Flagstaff, Arizona. Tombaugh's meticulous observations and analysis of photographic plates led to the identification of the ninth planet in our solar system. His discovery of Pluto was a significant contribution to the field of astronomy and expanded our understanding of the outer reaches of our solar system.Rate this question:

What's the average temperature on Pluto?
- A.
-275 F
- B.
-620 F
- C.
-125 F
- D.
-375 F
Correct Answer
D. -375 FExplanation
Pluto, being the farthest planet from the Sun in our solar system, experiences extremely low temperatures. The average temperature on Pluto is approximately -375 degrees Fahrenheit. This frigid temperature is due to the lack of sunlight and the thin atmosphere on Pluto, which is composed mostly of nitrogen and methane. The extremely low temperatures make Pluto an inhospitable and frozen world.Rate this question:

Pluto, MakeMake, Haumea and ____________ are Plutoids.
Correct Answer
ErisExplanation
Pluto, MakeMake, Haumea, and Eris are all classified as Plutoids. The term "Plutoid" refers to dwarf planets that are similar to Pluto in terms of their characteristics and location in the solar system. These objects are located beyond Neptune in the Kuiper Belt, a region filled with icy bodies. Eris, like Pluto, possesses a sufficient mass to be rounded by its own gravity and is considered one of the largest dwarf planets. Therefore, Eris fits the criteria to be classified as a Plutoid alongside Pluto, MakeMake, and Haumea.Rate this question:

Pluto is a _________ planet.
Correct Answer
DwarfExplanation
Pluto is referred to as a dwarf planet because it does not meet the criteria to be classified as a full-fledged planet. In 2006, the International Astronomical Union redefined the definition of a planet, and Pluto did not meet the requirement of clearing its orbit of other debris. As a result, it was reclassified as a dwarf planet, which is a distinct category of celestial bodies that share some similarities with planets but do not fulfill all the criteria.Rate this question:
- 7.
Pluto's orbit is _______ years.
Correct Answer
248Explanation
Pluto's orbit is 248 years long. This means that it takes Pluto approximately 248 Earth years to complete one orbit around the Sun. This is a significant amount of time compared to the shorter orbital periods of other planets in our solar system.Rate this question:
- 8.
Pluto has _____ moons.
Correct Answer
3Explanation
Pluto has three moons. This means that there are three natural satellites that orbit around Pluto. These moons are named Charon, Styx, Nix, Kerberos, and Hydra. While Pluto was once considered the ninth planet in our solar system, it was reclassified as a dwarf planet in 2006. Despite its change in classification, Pluto still has a significant number of moons compared to other dwarf planets.Rate this question:
- 9.
Pluto is composed of ______________________ and other ______________.
Correct Answer
Frozen Methane and IcesExplanation
Pluto is composed of frozen methane and other ices. This means that the surface of Pluto is primarily made up of frozen methane, as well as other types of ices. Methane is a volatile compound that freezes at low temperatures, making it a common component of Pluto's icy surface. The presence of other ices suggests that there are various frozen compounds on Pluto, contributing to its composition.Rate this question:
