Question

Which planet is called the dwarf planet?
A)Mercury
B)Pluto
C)Mars
D)Uranus

Answer 1

Hint: A dwarf planet, a body other than a natural satellite (moon) orbiting the Sun, which, for practical purposes, is smaller than the planet Mercury but large enough for its own gravity to significantly surround its shape.

Complete answer:
Mercury- Mercury is the Solar Systems smallest and nearest planet to the earth. It takes 87.97 Earth days to orbit around the Sun, the shortest of all the planets in the Solar System.

Pluto- Pluto is known to be a minor planet since it has not cleared the neighborhood surrounding its orbit. It orbits in a disc-like field outside Neptune's orbit called the Kuiper belt, a remote region filled by frozen bodies left over from the forming of the solar system.

Mars- Mars is the Sun's fourth planet and the second smallest planet in the Solar System, larger than Mercury alone. Mars bears the name of the Roman god of war in English and is also referred to as the Red World. Mars is almost half the circumference of the Globe, having a surface area just marginally smaller than the average dry land area of the Earth. Mars is less compact than Earth, having only 15 percent of the volume of Earth and 11 percent of the density of Earth, resulting in about 38 percent of the gravity of the Earth's surface.

Uranus- Talking about the Solar System, it has the third-largest planetary radius and the fourth-largest planetary mass. Uranus is identical to Neptune in structure, and both have bulk chemical compositions that vary from those of Jupiter and Saturn, the larger gas giants.

Hence, the correct answer is option (B)

Note: 1)In our solar system, Eris is one of the largest known dwarf planets. It is about the same size as Pluto.
2)Venus doesn’t have any moons.
3)Neptune has supersonic winds.
