What is the relative size of the Earth sun and moon?
Earth, Moon and Sun
| Object | Eq. Diameter (km) | Diameter Relative to Earth |
|---|---|---|
| Earth | 12,756 | 1.0x |
| Moon | 3,475 | 0.27x |
| Sun | 1,391,016 | 109.1x |
What is the sun’s relative size to Earth?
The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8\% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
Why does the sun and the Moon appear to be the same size from Earth?
Believe it or not, it actually is just a coincidence — and a happy one at that. The Moon and Sun have virtually the same angular size in our sky because the Sun is about 400 times wider than the Moon, but it’s also about 400 times farther away.
What is the Moon’s size relative to the 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 miles (1,737.5 kilometers).
Who is bigger in size sun or Earth?
Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.
Is the moon and sun the same size?
The sun and the moon are about the same size when you look at them in the sky, though that’s just thanks to the coincidence that the sun is about 400 times farther away than the moon and also about 400 times bigger. Another fun coincidence is that the radius of the sun is about twice the distance to the moon.
What is the size of the moon?
1,079.6 mi
Moon/Radius
What is the size of the Earth?
3,958.8 mi
Earth/Radius
Is the sun bigger than the Earth and moon?
Bottom line: The sun’s diameter is about 400 times larger than that of the moon – and the sun is also about 400 times farther from Earth. So the sun and moon appear nearly the same size as seen from Earth.
