Space And Solar System Quiz!

Pluto is considered 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 one of the criteria which requires a planet to have cleared its orbit of other debris. As a result, it was reclassified as a dwarf planet.

Jupiter is the correct answer because it is the largest planet in our solar system. It is known for its massive size and is more than twice as large as all the other planets combined. Jupiter's immense size is due to its strong gravitational pull, which allows it to gather a large amount of gas and dust during its formation. This makes Jupiter a gas giant, consisting mostly of hydrogen and helium. Its size also contributes to its distinct features, such as its iconic Great Red Spot and numerous moons.

Neil Armstrong is the correct answer because he was the first person to set foot on the Moon. On July 20, 1969, Armstrong, along with Buzz Aldrin, became the first astronauts to land on the Moon as part of NASA's Apollo 11 mission. Armstrong famously took his first step onto the lunar surface and uttered the iconic words, "That's one small step for man, one giant leap for mankind." His historic achievement marked a significant milestone in human space exploration.

Saturn is the correct answer because it is the only planet listed that has a ring system. Jupiter, Mars, and Neptune do not have visible ring systems like Saturn does. The rings around Saturn are made up of ice particles, dust, and rocks, and they are one of the most distinctive features of the planet.

The first living creature to be sent into space was a dog. This is a well-known fact in the history of space exploration. The Soviet Union launched a stray dog named Laika aboard the spacecraft Sputnik 2 in 1957. Unfortunately, Laika did not survive the mission, but her journey paved the way for human space travel.

Venus is known as the morning star or evening star because it is often visible in the sky during these times. Due to its proximity to the Sun, Venus can be seen shortly before sunrise or shortly after sunset, appearing as a bright star-like object. Its brightness and visibility make it easily distinguishable, hence earning the title of morning star or evening star.

The correct answer is Mars & Jupiter. The Asteroid Belt is a region in our solar system located between the orbits of Mars and Jupiter. It is filled with numerous small rocky objects, known as asteroids, which orbit the Sun. These asteroids are remnants from the early formation of our solar system and their presence in the Asteroid Belt is due to the gravitational influence of Jupiter, which prevented them from coalescing into a planet.

Deimos and Phobos are the correct answer because they are the two satellites of Mars. Deimos is the smaller and outermost moon, while Phobos is the larger and innermost moon. They were both discovered in 1877 by American astronomer Asaph Hall. These two moons are irregularly shaped and are thought to be captured asteroids. They play a significant role in the study of Mars and its gravitational influence on them provides valuable information about the planet's interior and evolution.

Aryabhata is the correct answer because it was the first Indian satellite launched into space. It was named after the famous Indian mathematician and astronomer, Aryabhata. Launched on April 19, 1975, Aryabhata played a significant role in kickstarting India's space program and paved the way for future satellite missions.
