    Which planet is the largest planet?  

    • Pluto

    • Jupiter

    • Uranus

    • Earth

    • The sun

    Correct Answer
    A. Jupiter
    Explanation
    Jupiter is the largest planet in our solar system. It has a diameter of about 86,881 miles, making it more than 11 times the size of Earth. Jupiter's large size is due to its massive atmosphere, which is primarily composed of hydrogen and helium gases. Its immense size and strong gravitational pull have also allowed it to accumulate a large number of moons, with over 80 currently known.

     The sun has a life cycle.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the sun, like all stars, has a life cycle. It is currently in the main sequence phase, where it fuses hydrogen into helium in its core. Eventually, it will exhaust its hydrogen fuel and expand into a red giant. After that, it will shed its outer layers and become a white dwarf. Eventually, it will cool down and fade away, marking the end of its life cycle.

    The sun will burn out.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement "The sun will burn out" is true. According to scientific theories, the sun is a finite source of energy and will eventually exhaust its fuel. This process is known as stellar evolution, where the sun will expand into a red giant and eventually shed its outer layers, leaving behind a dense core called a white dwarf. While this process will take billions of years, it is inevitable that the sun will eventually burn out.

    Rate this question:

    What is a white dwarf?

    • A small guy with a beard

    • A meteorite that got stuck in the atmosphere

    • A burnt out star

    Correct Answer
    A. A burnt out star
    Explanation
    A white dwarf is a burnt out star. After a star exhausts its nuclear fuel, it undergoes a series of transformations. If the star is not massive enough to explode in a supernova, it will collapse under its own gravity and become a white dwarf. These objects are extremely dense and hot, but they no longer generate energy through nuclear fusion. Instead, they radiate away their residual heat over billions of years until they eventually cool down and fade away.
