1.
Venus is the ______ planet from the Sun.
Correct Answer
C. 2nd
Explanation

2.
Venus is named after the Roman goddess of what?
Correct Answer
D. Love
Explanation
Venus is named after the Roman goddess of love. In Roman mythology, Venus was the goddess of love, beauty, desire, sex, fertility, and prosperity. She was often associated with the qualities of love, passion, and desire, which is why the planet Venus was named after her. The planet is known for its beauty and brightness, just like the goddess herself.
3.
Venus has clouds made of ______.
Correct Answer
C. SulpHuric acid
Explanation
Venus has clouds made of sulphuric acid because the atmosphere of Venus is composed mostly of carbon dioxide with traces of other gases, including sulphur dioxide. The high temperatures and pressure on Venus cause the sulphur dioxide to react with other substances in the atmosphere, forming sulphuric acid clouds. These clouds completely cover the planet and create a thick, toxic atmosphere.
4.
How many moons does Venus have?
Correct Answer
A. 0
Explanation
Venus does not have any moons. Moons are natural satellites that orbit around a planet, and Venus does not have any objects orbiting around it. Therefore, the correct answer is 0.
5.
One solar day on Venus is equal to how many solar days on Earth?
Correct Answer
D. 117
Explanation
One solar day on Venus is equal to 117 solar days on Earth. This means that it takes Venus approximately 117 Earth days to complete one full rotation on its axis. In comparison, Earth takes approximately 24 hours to complete one rotation. Therefore, Venus has a much longer day-night cycle than Earth.
6.
Venus rotates in the _______ direction as most other planets.
Correct Answer
B. Opposite
Explanation
Venus rotates in the opposite direction as most other planets. This means that while most planets rotate counterclockwise when viewed from above the North Pole, Venus rotates clockwise. This is known as retrograde rotation. The exact reason for Venus' opposite rotation is not fully understood, but it may be due to a collision with a large object in the past or gravitational interactions with other celestial bodies.
7.
How many rings does Venus have?
Correct Answer
C. 0
Explanation
Venus does not have any rings. This is because Venus is a terrestrial planet, similar to Earth, and does not have the necessary conditions or gravitational forces to form and maintain rings around it. Unlike gas giants such as Saturn, which have prominent ring systems, Venus lacks the necessary material and dynamics to support ring formation. Therefore, the correct answer is 0.
8.
Venus is the _______ brightest in the night sky.
Correct Answer
A. 2nd
Explanation
Venus is the second brightest in the night sky. This means that there is only one other celestial object that is brighter than Venus when observed at night.
9.
Who sent the first mission to Venus in 1961?
Correct Answer
D. Russia
Explanation
In 1961, Russia was the first country to send a mission to Venus. This mission, known as Venera 1, was an unmanned spacecraft that aimed to study the planet's atmosphere and collect data on its surface. Although the mission was not entirely successful and failed to make a direct impact on Venus, it marked a significant milestone in space exploration as the first attempt to reach another planet.
10.
Venus has what kind of core?
Correct Answer
B. Iron
Explanation
Venus is a terrestrial planet similar to Earth, and like Earth, it is believed to have a core made primarily of iron. This is based on studies of Venus's magnetic field, which suggests the presence of a solid iron core. Additionally, the composition of Venus's mantle and crust also supports the idea of an iron core. Therefore, the correct answer is iron.
