Which of the following planets of the inner solar system has zero moons ?

  • A.Venus
  • B.Mars
  • C.Pluto
  • D.Neptune

Answer: A

The inner planet with no moons is Venus.

The inner (terrestrial) planets are Mercury, Venus, Earth and Mars. Mercury and Venus have no natural satellites.

Mars has two moons, Phobos and Deimos. Neptune is an outer planet with many moons, and Pluto is a dwarf planet beyond Neptune with five moons, so neither is an inner planet at all.

Earth has one moon, the only moon among the inner planets other than the two small moons of Mars.
