10 Best Fictional Planets In Sci-Fi Movies

10. Paradise, Alien

Featuring in Ridley Scott's Alien: Covenant (2017), Paradise was, at one time, a haven of the best things nature had to offer, with two moons and a serenely, supremely inhabitable environment.

Also known as Planet 4, Paradise was perhaps the home of a city of Engineers, perhaps not; only Ridley Scott (and his upcoming Alien: Paradise) knows for sure. An alternative theory runs that the planet was inhabited by another race created in the Engineers' image, who awaited the return of their gods - something backed by their welcoming of the android David's Juggernaut upon its return above their city.

Either way, the seemingly peaceful inhabitants of Paradise are toast, laid to waste by David, who unleashed a dark plague upon the planet that reaped it of its natural resources, tore apart its ecosystem and brought it to ruin. Now, the planet is overrun with every breed of -morph that David brought to life (Neo-, Praeto-, Ovo-, etc) and, Xenomorph Prime be damned, this looks more like the Xenomorph's origin planet than the Engineers'.
