The distance between the Moon and Earth varies from around 356,400 km (221,500 mi) to 406,700 km (252,700 mi) (apogee), making the Moon's distance and apparent size fluctuate up to 14%. [202] [203] On average the Moon's angular diameter is about 0.52°, roughly the same apparent size as the Sun (see § Eclipses).
3.476 Mm – diameter of Earth's Moon; 3.643 Mm – diameter of Io, a moon of Jupiter; 4.821 Mm – diameter of Callisto, a moon of Jupiter; 4.879 Mm – diameter of Mercury; 5.150 Mm – diameter of Titan, the largest moon of Saturn; 5.262 Mm – diameter of Jupiter's moon Ganymede, the largest moon in the Solar System; 6.371 Mm – radius of ...
A lunar distance, 384,399 km (238,854 mi), is the Moon's average distance to Earth. The actual distance varies over the course of its orbit. The image compares the Moon's apparent size when it is nearest and farthest from Earth.
An enormous mosaic of Stephan’s Quintet is the largest image to date from NASA’s James Webb Space Telescope, covering about one-fifth of the Moon’s diameter.
Charon, discovered in 1978, has the distinction of being the solar system's largest moon relative in size to the planet it orbits. It is about half the diameter and an eighth the mass of Pluto, a ...
Schematic illustration of the internal structure of the Moon. Several lines of evidence imply that the lunar core is small, with a radius of about 350 km or less. [5] The diameter of the lunar core is only about 20% the diameter of the Moon itself, in contrast to about 50% as is the case for most other terrestrial bodies.
The moon’s surface is dominated by hydrocarbons, highly combustible organic compounds, like methane and ethane. ... At 525 feet in diameter, Dimorphos, which orbits the asteroid Didymos, is ...
Size comparison of Europa (lower left) with the Moon (top left) and Earth (right) Europa is slightly smaller than the Earth's moon . At just over 3,100 kilometres (1,900 mi) in diameter , it is the sixth-largest moon and fifteenth-largest object in the Solar System .
