    What is the fourth planet from the Sun?

    • Mercury

    • Venus

    • Jupiter

    • Mars

    Correct Answer
    A. Mars
    Explanation
    Mars is the fourth planet from the Sun. It is known for its reddish appearance, which is caused by iron oxide (or rust) on its surface. Mars has a thin atmosphere and is home to the largest volcano and the deepest canyon in the solar system. It is also a focus of scientific exploration, with several missions sent to study its geology, climate, and the possibility of past or present life.

    How many planets are in our solar system? - ProProfs

    How many planets are in our solar system?

    • 9

    • 10

    • 8

    • Millions

    Correct Answer
    A. 8
    Explanation
    There are 8 planets in our solar system. The correct answer is 8 because Pluto, which was previously considered the ninth planet, was reclassified as a dwarf planet in 2006. Therefore, the current count of planets in our solar system is 8, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

    What is at the center of the solar system? - ProProfs

    What is at the center of the solar system?

    • Earth

    • Sun

    • Moon

    • Jupiter

    Correct Answer
    A. Sun
    Explanation
    The sun is at the center of the solar system. It is a star, and all the planets, including Earth, orbit around it. The sun is much larger and more massive than any other object in the solar system, and its gravitational pull keeps all the planets in their orbits. It provides heat and light to the planets, including Earth, making it essential for sustaining life.

    Which is the last planet in the solar system? - ProProfs

    Which is the last planet in the solar system?

    • Mercury

    • Jupiter

    • Neptune

    • Pluto

    Correct Answer
    A. Neptune
    Explanation
    Neptune is the last planet in the solar system because it is the eighth and farthest known planet from the Sun. It is located beyond Uranus and is known for its deep blue color. Neptune is a gas giant and has a thick atmosphere composed mainly of hydrogen and helium. It is also known for its strong winds and the presence of a large dark spot called the Great Dark Spot.

    The sun is the biggest planet in our solar system. - ProProfs

    The sun is the biggest planet in our solar system.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is incorrect. The sun is not a planet, but a star. It is the largest and central body in our solar system, but it is not classified as a planet. Planets, such as Earth, Mars, and Jupiter, orbit around the sun. Therefore, the correct answer is False.

    Which planet rolls on its side like a bowling ball?  - ProProfs

    Which planet rolls on its side like a bowling ball? 

    • Earth

    • Jupiter

    • Saturn

    • Uranus

    Correct Answer
    A. Uranus
    Explanation
    Uranus is the correct answer because it is the only planet in our solar system that rolls on its side. This is due to its unique axial tilt, which causes it to rotate almost perpendicular to its orbital plane. As a result, Uranus appears to roll on its side like a bowling ball as it orbits the Sun. This distinctive feature sets Uranus apart from the other planets and makes it an interesting object of study for astronomers.

    Mercury is the hottest planet in our solar system. - ProProfs

    Mercury is the hottest planet in our solar system.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The correct answer is False because although Mercury is the closest planet to the sun, it is not the hottest planet in our solar system. Venus holds the title for being the hottest planet, with a thick atmosphere that traps heat and creates a runaway greenhouse effect, resulting in extremely high temperatures.

    The solar system has millions of stars. - ProProfs

    The solar system has millions of stars.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The solar system actually has only one star, which is the Sun. While there are millions of stars in the universe, the solar system specifically refers to the Sun and all the celestial bodies that orbit it, such as planets, moons, asteroids, and comets.

    Rate this question:

  • 10. 
    How many stars does our solar system have? - ProProfs

    How many stars does our solar system have?

    • 1

    • 10

    • 532

    • Millions

    Correct Answer
    A. 1
    Explanation
    Our solar system has only one star, which is the Sun. The Sun is a yellow dwarf star located at the center of our solar system. It provides heat, light, and energy to the planets and other celestial bodies in our system. The other options, 10, 532, and millions, are incorrect as they do not represent the number of stars in our solar system.
