Jan 30, 2025 · Earth's Moon has a core, mantle, and crust. The Moon’s core is proportionally smaller than other terrestrial bodies' cores. The solid, iron-rich inner core is 149 miles (240 kilometers) in radius. It is surrounded by a liquid iron shell 56 miles (90 kilometers) thick.

Jan 19, 2024 · By dividing Earth’s radius by the Moon’s, we find that Earth is roughly 3.67 times larger in radius than the Moon. This means, that roughly it would take almost 4 moons placed end-to-end to equal the radius of the Earth.

Both of those are important, but most important is the moon’s relative size to Earth, as the moon is just about a quarter of Earth’s diameter with about 1/81th of its mass, with most moons being much, much smaller.

May 29, 2023 · How big is the Moon compared to the Earth? It is almost four times smaller. The Earth’s dimensions are as follows: the average radius is approximately 6,371 km; diameter is 12,742 km; equator circumference – 40,075 km. Simple mathematical calculations show us …

The Earth’s diameter is 12,742 km (7,918 mi) which is almost 4 times that of the Moon. The Moon’s volume looks like a daunting figure. But factually it is a mere 2% of the Earth’s volume.

Sep 5, 2016 · The moon diameter is always 2,159 miles (3,474 km), which is 27% of Earth's diameter of 7,901 miles (12,715.43 km) at the poles.

Mar 7, 2022 · How big is the moon compared to Earth? The moon, like the Earth, isn’t a perfect sphere, so we measure its size by its mean radius, which is 1,079.6 miles (about 1,737.4 kilometers), with a...

28 light-seconds. This is about thirty times the diameter of Earth. The Moon's apparent size in the sky is almost the same as that of the Sun, since the star is about 400 times the lunar distance and diameter. Therefore, the Moon covers the Sun nearly precisely during a total solar eclipse.

Jan 3, 2023 · Earth’s moon is the fifth largest moon in the solar system with a diameter of 2,159-miles (3,475-kilometers), making it about 25% the size of Earth.

The Moon is Earth's only natural satellite.We usually see it in the night sky but also during the day. Some other planets also have moons or natural satellites. Our moon is about one-fourth of the width of the Earth. [8] Because it is far away it looks small, about half a degree wide. The …

28 light-seconds. This is about thirty times the diameter of Earth. The Moon's apparent size in the sky is almost the same as that of the Sun, since the star is about 400 times the lunar distance and diameter. Therefore, the Moon covers the Sun nearly precisely during a total solar eclipse.

Jul 12, 2022 · How big is the Moon compared to Earth? – The moon is a bit more than one-fourth (27 percent) the size of Earth, a much larger ratio (1:4) than any other planets and their moons. Earth’s moon is the fifth largest moon in the solar system. The moon’s mean radius is 1,079.6 …

Feb 23, 2025 · Size compared to Earth's Moon: 89.8% Year discovered: 1610 Europa is one of Jupiter’s biggest moons and easily one of the most interesting. Its surface is covered in cracked ice, with long, dark streaks that suggest the ice shifts and moves over time. Beneath that …

Aug 8, 2024 · In comparison, the volume of the Moon is about 2.195 x 10^10 cubic kilometers, while the volume of Earth is about 1.08321 x 10^17 cubic kilometers. This means that the Moon is about 0.0203...
