I AM THE NIGHT

The planets, moons and Death Stars seen in the original (theatrical) Star Wars trilogy to scale.

Alderaan, famous for being destroying in A New Hope, is the closest in size to the Earth with a diameter of 12,500 km vs Earth’s 12,742 km average diameter.

Hoth is larger, but still the closest in size to Mars, with a diameter of 7,200 km vs Mars’ 6,779 km.

Endor, the smallest of the bodies to appear in the original trilogy, has a diameter of 4,900 km which makes it very slightly larger than our solar system’s smallest planet, Mercury which has a diameter of 4,879 km.

Of the gas giants seen in Star Wars, Bespin is very similar in size to Saturn (116,464 km average diameter) but is still quite a bit smaller than Jupiter (139,822 km), which in turn is much smaller than Yavin Prime, the largest planet to appear in the original trilogy.

What if the Moon was colonized?

Cassini Approaches Saturn

(via APOD; Image Credit: Cassini Imaging Team, SWRI, JPL, ESA, NASA )

Cassini, a robot spacecraft launched in 1997 by NASA, became close enough in 2002 to resolve many rings and moons of its destination planet: Saturn. At that time, Cassini snapped several images during an engineering test. Several of those images were combined into the contrast-enhanced color composite featured here. Saturn’s rings and cloud-tops are visible toward the image bottom, while Titan, its largest moon, is visible as the speck toward the top. When arriving at Saturn in July 2004, the Cassini orbiter began to circle and study the Saturnian system. A highlight was when Cassini launched the Huygens probe that made an unprecedented landing on Titan in 2005, sending back detailed pictures. Now nearing the end of its mission, Cassini is scheduled to embark on a Grand Finale phase in late 2016 where it will repeatedly dive between the giant planet and its innermost rings.
