Earth is the only planet known to have only 1 moon.
because it wanted to. :)
Mercury and Venus. They are the only planets without a moon.
none of them have more than 1 moon
because only half of the visible moon is lite. we only see half the moon so only a quarter of the moon is lite.===================================Another take:After the New Moon . . .-- The 'first quarter' is the phase that's seen after 1/4 of the timeuntil the next New Moon has passed.-- The 'third quarter' is the phase that's seen after 3/4 of the timeuntil the next New Moon has passed.
On Earth, there is more gravity than on the moon. There is no air resistance on the moon.
Only Earth has exactly one moon.
The Earth has only 1 moon.
Our Earth has only the one moon.
Mercury, Venus, Earth and Mars
1/2 moon
No the earth only has one moon in its orbit
The reason you only see one side of the moon is because you only see side of the moon is facing towards the Earth which means the back of the moon is nonvisible.
Earth
because it wanted to. :)
Gravity is there on moon, but its only 1/6th that there on earth
Because the gravity of the moon is only 1/3 of that on Earth.
no because there is only one you just like there is only moon and that is what makes us original.
