1.
Saturn is regarded as the first planet to have?
Correct Answer
D. Rings
Explanation
Saturn is regarded as the first planet to have rings. This is because Saturn's rings are the most prominent and easily visible compared to any other planet in our solar system. The rings are made up of countless small particles of ice and rock, and they encircle the planet. The discovery of Saturn's rings was made by Galileo Galilei in 1610, and since then, they have been a defining feature of the planet.
2.
How much is the density of Saturn in comparison to water?
Correct Answer
B. 0.69
Explanation
The density of Saturn is 0.69 in comparison to water. Density is a measure of how much mass is contained in a given volume. A density of 0.69 means that Saturn is less dense than water, indicating that it would float if placed in a body of water. This suggests that Saturn is primarily composed of lighter elements and gases, such as hydrogen and helium, which are less dense than water.
3.
What is the mass of Saturn in comparison to the mass of earth?
Correct Answer
A. 95 times
Explanation
Saturn's mass is 95 times greater than Earth's mass. This means that Saturn is much larger and more massive than Earth.
4.
The first spacecraft to visit Saturn is?
Correct Answer
D. Pioneer 10
Explanation
Pioneer 10 was the first spacecraft to visit Saturn. Launched by NASA in 1972, it successfully completed a flyby of the planet in 1979. It provided valuable data and close-up images of Saturn, its rings, and its moons. Voyager 1 and Voyager 2 were also spacecraft that visited Saturn, but they were launched after Pioneer 10. Pioneer 11, on the other hand, was launched before Pioneer 10 and did not reach Saturn, making it an incorrect answer.
5.
How many approximate Earth years does it take Saturn to make just one revolution all around the Sun?
Correct Answer
C. 29
Explanation
Saturn takes approximately 29 Earth years to make one revolution around the Sun. This is because Saturn is located further away from the Sun compared to Earth, so it takes a longer time to complete its orbit.
6.
In Roman mythology, Saturn is known as the god of what?
Correct Answer
B. Agriculture
Explanation
Saturn is known as the god of agriculture in Roman mythology. He was associated with fertility, abundance, and the harvest. Saturn was believed to have taught humans the art of farming and the cultivation of crops. He was also associated with the Golden Age, a time of peace and prosperity when the earth was said to have been abundant with crops. Therefore, the correct answer is Agriculture.
7.
Which of the following is mostly the atmosphere of Saturn?
Correct Answer
D. Sulfur and Hydrogen
8.
What is the thickness of Saturn's rings?
Correct Answer
A. 1 kilometer
Explanation
Saturn's rings have a thickness of approximately 1 kilometer. The rings are made up of countless small particles, ranging in size from tiny grains to large boulders. Despite their appearance from a distance, the rings are actually very thin compared to their vast width. This thinness is due to the gravitational forces of Saturn and its moons, which keep the particles confined to a relatively narrow plane.
9.
What is the diameter of Saturn?
Correct Answer
A. 120,000km
Explanation
Saturn's diameter is 120,000km. This means that if you were to draw a straight line from one side of Saturn to the other, it would measure 120,000km in length.
10.
The dark region located between the two brightest rings of Saturn is called?
Correct Answer
C. Cassini's Division
Explanation
Cassini's Division refers to the dark region located between the two brightest rings of Saturn. This division is named after the Italian-French astronomer Giovanni Domenico Cassini, who first observed and described it in the 17th century. The division is a gap in Saturn's rings caused by gravitational interactions with Saturn's moon, Mimas. The particles within this region are less densely packed, resulting in a darker appearance compared to the surrounding rings.
