1.
Which is the hottest planet in our solar system?
Correct Answer
C. Venus
Explanation
The Giant Red Spot is hypothesized to be a raging storm which has been around for thousands of years.
2.
Which planet in the solar system sports a giant red spot?
Correct Answer
A. Jupiter
Explanation
Jupiter is the correct answer because it is the only planet in the solar system that has a giant red spot. The giant red spot is a massive storm that has been observed on Jupiter for over 300 years. It is a high-pressure system that is twice the size of Earth and is characterized by its distinct red color. The spot is constantly changing in shape and size, but it has remained a prominent feature of Jupiter's atmosphere.
3.
Which planet in the solar system has a tilt of almost 90 degrees so that it almost rotates on its equator?
Correct Answer
B. Uranus
Explanation
Uranus is the correct answer because it is the only planet in the solar system that has a tilt of almost 90 degrees. This means that its axis of rotation is almost parallel to its orbital plane, causing it to almost rotate on its equator. The other planets mentioned in the options have different tilts and do not exhibit this unique characteristic.
4.
Between which two planets lies the Asteroid Belt?
Correct Answer
A. Mars and Jupiter
Explanation
The Asteroid Belt lies between Mars and Jupiter. This region is filled with numerous small rocky objects called asteroids. The gravitational pull of Jupiter prevented these asteroids from forming into a planet, resulting in the formation of the belt.
5.
How many days does Mercury take to go around the Sun once?
Correct Answer
A. 88
Explanation
Mercury takes 88 days to go around the Sun once. This is because Mercury is the closest planet to the Sun and has the shortest orbital period of all the planets in our solar system. Its close proximity to the Sun causes it to have a faster orbital speed, completing its journey around the Sun in just 88 days.
6.
Which planet is named after the Roman god Of War?
Correct Answer
C. Mars
Explanation
Mars is named after the Roman god of war because of its reddish appearance, resembling the color of blood. In Roman mythology, Mars was the god of war and second in importance only to Jupiter. The planet's reddish hue is due to iron oxide, or rust, on its surface. The association with the god of war is fitting, as Mars is often referred to as the "Red Planet" and has long been associated with conflict and aggression.
7.
Who planet was accidentally discovered by William Herschel in 1781, during his search for double stars?
Correct Answer
C. Uranus
Explanation
William Herschel accidentally discovered the planet Uranus in 1781 while he was searching for double stars. This discovery was a significant contribution to astronomy as it expanded our understanding of the solar system and challenged the existing beliefs about the number of planets.
8.
How many planets in the Solar System have been found to have rings?
Correct Answer
D. 4
Explanation
Four planets in the Solar System have been found to have rings. These planets are Saturn, Jupiter, Uranus, and Neptune. Saturn is the most well-known planet with rings, but the other three also have faint ring systems. These rings are made up of small particles of ice and rock that orbit around the planets. The rings of Saturn are the most prominent and easily visible, while the rings of the other three planets are much less noticeable. Nonetheless, all four planets have been confirmed to have rings.
9.
Which planet has the highest number of natural satellites in the Solar System?
Correct Answer
B. Jupiter
Explanation
Jupiter has the highest number of natural satellites in the Solar System. It is known to have at least 79 moons, with more potentially yet to be discovered. This is significantly more than any other planet in our Solar System. Jupiter's large size and strong gravitational pull allow it to capture and retain a large number of moons, making it the planet with the highest number of natural satellites.
10.
Which planet has the lowest density in our solar system, so much so that it would float on water if we were to bring it to earth.
Correct Answer
C. Saturn
Explanation
Saturn has the lowest density in our solar system, which is why it would float on water if we were to bring it to Earth. This is due to its composition, primarily consisting of gases such as hydrogen and helium, making it less dense than the other planets.
