Question

Which of the given two planets are the only planets without moons ?
A. Mercury, Venus
B. Mars, Venus
C. Jupiter, Saturn
D. Earth, Mercury

Answer 1

Hint: Planets are the celestial body moving in an elliptical orbit around a star (like sun). Because the sun is also a star.

Complete step-by-step answer:

As we know that the planets are the celestial bodies that are in orbit around the Sun and have cleared the neighbourhood around its orbit.

And there are total eight major planets in our solar system and that were,

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

The moon is known as natural satellites and its most common usage is that it is an astronomical body that orbits a planet or minor planet. And moons are non-luminous because they do not have their own light, they reflect the light from the sun.

And out of eight major planets six of them have moons. And that were,

Earth has one moon.

Mars has 2 moons.

Jupiter and Saturn have 53 moons.

Uranus has 27 moons and Neptune have 14 moons,

So, only Mercury and Venus have no moon.

Hence, the correct option will be A.

Note: Whenever we come up with this type of problem then we should remember that the number of moons on each planet can increase after some years because research is always going on. So, counting might go up and down after more and more research on solar system
