Planetology is the study of sun, moon, stars, planets and other heavenly bodies. This is also known as Planet science, which looks through the existence of satellites in planets, the rotation, and revolution of the sun around each planet. This study is for bodies of the solar system and different from Geography. Take this quiz now!

Which of these planets possesses rings?
-
Jupiter
-
Pluto
-
Saturn
-
Uranus
Correct Answer
A. SaturnExplanation
Saturn possesses rings. Unlike the other planets listed, Saturn is well-known for its prominent and extensive ring system. These rings are made up of countless particles, ranging in size from tiny grains to large chunks of ice and rock. The rings of Saturn are a distinctive feature that sets it apart from other planets in our solar system.Rate this question:

16
Correct Answer
A. 12Explanation
Jupiter has 12 satellites. Satellites are natural or artificial objects that orbit around a planet. In the case of Jupiter, its 12 satellites are known as the Galilean moons, named after the astronomer Galileo Galilei who discovered them. These moons are Io, Europa, Ganymede, and Callisto, and they are the largest and most well-known satellites of Jupiter. They were first observed by Galileo in 1610 and have been studied extensively since then.Rate this question:

Which of these is not a planetary body?
-
Asteroids
-
Stars
-
Quartz
-
Neptune
Correct Answer
A. AsteroidsExplanation
Asteroids are not considered planetary bodies because they are small rocky objects that orbit the Sun, but they are not large enough to be classified as planets. Stars, Neptune, and Quartz are all considered planetary bodies in different ways. Stars are massive celestial objects that produce light and heat through nuclear reactions. Neptune is a planet in our solar system, and Quartz is a mineral commonly found on Earth.Rate this question:

What is the only source of light to the solar system?
-
Sun
-
Moon
-
Saturn
-
Uranus
Correct Answer
A. SunExplanation
The Sun is the only source of light to the solar system. It emits light and heat through a process called nuclear fusion, which occurs at its core. The Sun's light is essential for life on Earth as it provides energy for photosynthesis and regulates the planet's climate. The Moon, Saturn, and Uranus do not emit their own light and instead reflect the sunlight that reaches them. Therefore, the Sun is the correct answer as it is the primary source of light in the solar system.Rate this question:

Which of these planets is referred to as "Earth Twin"?
-
Venus
-
Mars
-
Mercury
-
Neptune
Correct Answer
A. VenusExplanation
Venus is referred to as the "Earth Twin" because it is similar in size and composition to Earth. It is often called the Earth's sister planet as it is the closest in size and has a similar rocky structure. Venus also has a similar gravity and is located in the habitable zone of the solar system. However, despite these similarities, Venus has a harsh environment with extreme temperatures and a thick atmosphere made up mostly of carbon dioxide, making it inhospitable for life as we know it.Rate this question:

What is the coldest planet in the solar system?
-
Venus
-
Mercury
-
Neptune
-
Uranus
Correct Answer
A. NeptuneExplanation
The coldest planet in our solar system is Neptune. This is largely due to its great distance from the Sun. Neptune, the eighth planet from the Sun, has an average surface temperature of around -214 degrees Celsius (-353 degrees Fahrenheit). This extremely cold temperature is because Neptune is about 30 astronomical units away from the Sun (one astronomical unit, AU, is the distance from the Earth to the Sun). Despite the presence of a hot core similar to other gas giants, which might be around 5,000 degrees Celsius, its distance from the Sun and minimal solar irradiance make its atmosphere extremely cold.Rate this question:

Which of the earth layer supports life?
-
Mesosphere
-
Biosphere
-
Hydrosphere
-
Stratosphere
Correct Answer
A. BiosphereExplanation
The biosphere is the correct answer because it is the layer of the earth that supports life. It includes all living organisms and their habitats, including plants, animals, and humans. The biosphere encompasses various ecosystems such as forests, oceans, and grasslands, where life thrives. It is the layer where interactions between living organisms and their environment occur, making it essential for the existence and sustainability of life on Earth.Rate this question:

Which of these planets has the highest number of satellites?
-
Jupiter
-
Venus
-
Uranus
-
Mecury
Correct Answer
A. JupiterExplanation
Jupiter has the highest number of satellites compared to Venus, Uranus, and Mercury. Jupiter is known for its large size and strong gravitational pull, which allows it to capture and retain a large number of moons. As of now, Jupiter has a total of 79 confirmed moons, making it the planet with the highest number of satellites in our solar system.Rate this question:
