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 ...

The seventh full moon of 2024, also known as the “Thunder Moon” and the “Buck Moon,” made a spectacular appearance in evening skies on Saturday. Rising in the east against the stars of the ...

(For humans, that means “down.”) In this formula, M is the mass of the planet or moon and R is its radius. OK, we already know what walking is like on Earth. Now what happens if you move to ...

Since a moon isn’t human-made, it’s a natural satellite. Currently, there are two main theories for why some planets have moons. Moons are either gravitationally captured if they are within what’s ...

Coronas also tend to circle tighter around the moon, creating a 10-degree rather than 22-degree radius. Fogbows are white rings, similar to lunar halos, forming low to the ground. They ...

The moon likely has a salty ocean underneath its ... It takes Ganymede about seven Earth days to orbit Jupiter. Ganymede's mean radius is 1,635 miles (2,631.2 km). Although Ganymede is larger ...
