Does the moon have a core?

Uncovering details about the lunar core is critical for developing accurate models of the moon's formation. The team's findings suggest the moon possesses a solid, iron-rich inner core with a radius of nearly 150 miles and a fluid, primarily liquid-iron outer core with a radius of roughly 205 miles.

What would happen if the sun exploded?

The good news is that if the Sun were to explode ? and it will eventually happen ? it wouldn't happen overnight. During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth. What if Earth had no gravity? Without gravity, humans and other objects would become weightless. That's because the planet would continue spinning, without exerting gravity to keep objects tied to it [source: Domanico]. A loss of gravity would also mean that the planet would stop pulling down air, water and Earth's atmosphere.

Keeping this in consideration, what 2 planets have 53 moons?

Saturn. Saturn has 53 moons that have been named. Saturn also has 29 moons awaiting confirmation. And another question, what is a ghost moon? A pair of so-called "ghost moons" have been documented orbiting Earth. These ghost moons, otherwise known as Kordylewski clouds, are large hazy clouds of dust. Discovered by Polish astronomer Kazimierz Kordylewski in 1961, his evidence was too faint to convince other scientists of their existence.

What if Earth had 2 moons?

If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth's rotation, causing the day to get longer.
