Jupiter is a really big object, its the largest planet in our solar system, so big that 1321 Earth’s can fit into it. This gas giant has 67 moons — four large moons and dozens of smaller ones.

The largest Jovian moon is Ganymede, the ninth largest object in the Solar System even larger than the planet Mercury; Ganymede is big enough to be a respectable planet in its own right, if it were orbiting the sun instead of Jupiter.

Ganymede is a half of the diameter of the Earth, but unlike Earth, its inhospitable although the recent studies show that a salty ocean is lurking beneath its surface — it could actually harbor more water than all of Earth’s surface water combined.

But what if Ganymede were size of Earth, instead? Actually, a better question would be, What if Earth were a moon of Jupiter? I know, the Earth will crash into Jupiter in less than 1 day, but assuming that nothing would change, only thing it would be a HUGE gas giant in our sky. So, What would it look like? It would be a great view in twilight! Here’s a render (we have to make some allowances for imagination):

Who else looks at this video and gets excited as if it were real? I do, It looks so cool!!!﻿

Its also interesting to imagine what the night sky might look like; Also can you imagine a solar eclipse with Jupiter?

What If the Moon were Replaced with Some of Our Planets? (link)



While Earth will never be a moon of Jupiter, this rendering still amazing; But maybe in the far future our descendants will be able to terraform one of Jupiter’ moon and then they could enjoy such amazing landscape.
