What is the true diameter of the Moon?
2,159.2 miles
The moon’s mean radius is 1,079.6 miles (1,737.5 kilometers). Double those figures to get its diameter: 2,159.2 miles (3,475 km), less than a third the width of Earth. The moon’s equatorial circumference is 6,783.5 miles (10,917 km).
How many moons can fit in the Earth?
50 moons
The Earth is significantly larger than the moon so around 50 moons would fit in the Earth.
How big is the Moon compared to Pluto?
The diameter of Pluto is only 2,390 km across. Just for comparison, that’s about 70% the diameter of the Moon. And it’s a fraction of the size of the Earth; about 18% of the Earth’s diameter. In terms of volume, Pluto only has 6.39 x 109 km3.

How many moons would fit into the sun’s diameter?
64.3 million Moons
It would take around 64.3 million Moons to fit inside the Sun, filling it whole. If we were to fill the Earth with Moons, we would need approximately 50 Moons to do so.
How big can a moon be?

Moon/Radius
How big is the diameter of the Moon in miles?
The diameter of the Moon is 3,474 km. (Diameter of the Moon in miles: 2,159 miles) And the polar diameter of the Moon is 3,471.94 km.
How big is the Moon from pole to pole?
Because it’s rotating, the Moon slightly flattens out. I say slightly, because we’re going to need decimals to really tell the difference. The equatorial diameter of the Moon is 3,476.28 km. And the polar diameter of the Moon is 3,471.94 km. In other words, the Moon’s diameter from side to side is 4.34 km more than its distance from pole to pole.
Is the Moon the same size as your thumb?
One way to test whether it’s just an illusion is to hold your thumb up next to the moon and compare the moon’s size with your thumbnail. When the moon is higher in the sky, look at it again; the moon will be the same size compared to your thumbnail.
