The Universe Quiz - Quiz

It’s mind-blowing to think that there’s literally an entire universe out there just waiting to be explored, and most of us don’t know a thing about it. Think you’ve got a decent knowledge of the universe? Let’s find out.


Questions and Answers
  • 1. 

    What Planet is closest to the sun?

    • A.

      Earth

    • B.

      Mercury

    • C.

      Jupiter

    Correct Answer
    B. Mercury
    Explanation
    Mercury is the closest planet to the sun. It orbits the sun at an average distance of about 36 million miles, which is much closer than Earth's average distance of about 93 million miles. This proximity to the sun also means that Mercury has a shorter year, completing one orbit in just 88 Earth days. Additionally, Mercury has a very thin atmosphere and extreme temperature variations, ranging from extremely hot during the day to extremely cold at night.

    Pluto is No Longer a Planet

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Pluto is no longer considered a planet because of a reclassification by the International Astronomical Union (IAU) in 2006. According to the new definition, a planet must meet three criteria: it must orbit the Sun, it must be spherical in shape, and it must have cleared its orbit of other debris. While Pluto orbits the Sun and is spherical, it has not cleared its orbit, as it shares its path with other objects in the Kuiper Belt. Therefore, it is now classified as a "dwarf planet" rather than a full-fledged planet.

    C. Yottameters
    Explanation
    The correct answer is Yottameters. Yottameter is the largest unit of measurement used for measuring galaxies. It is equal to one quadrillion kilometers or one trillion astronomical units. Given the vast size of galaxies, it is necessary to use such a large unit of measurement to accurately quantify their distances.

It is located approximately 1.04 billion light-years away from Earth and has an estimated diameter of about 6 million light-years. IC 1101 is classified as a supergiant elliptical galaxy and is believed to contain trillions of stars. Its immense size and mass make it a fascinating object of study for astronomers and astrophysicists.
