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.

The spacecraft Cassini captured some raw images of the icy Saturn moon, Enceladus from just 30 miles away. The small crescent moon erupted a geyser at its South Pole, backlit plumes filled with salt water and organic compounds. Read full article and view these pictures here.

On the care and keeping of your scientist

Congratulations on adopting a scientist! Regardless of their field they will require much coffee, free food, and love. Here are some field specific tips for keeping your scientist happy and healthy!

Biology: make sure they don't get overly invested in their model organism by reminding them about the flaws inherent in their system on a regular basis, but also make sure to join in when they criticize other models in favor of their own

Chemistry: don't let them do that 'just one more reaction' at 10 pm. make sure they get out of the lab and see the sun on a regular basis. try to keep them from partying too hard when they do leave the lab

Geology: humor their rock puns but don't let the lick the rocks (they will tell you they need to lick the rocks to identify them, but don't fall for it)

Astronomy: try not to let them become completely nocturnal. point out nice stars to them and look suitably impressed by their "pictures" of planets that don't look like anything to you

Physics: take them to the park on a regular basis to remind them that things larger than subatomic particles exist. bring a frisbee or a ball to play catch with and be impressed by their ability to calculate trajectories

Math: always make sure to have free batteries for their calculators and a mathmatica user guide on hand. Humor them when they tell you why space without angles is important

Ecology: make sure they remember to wear sunscreen and keep an eye on them in the field. Remind them to come inside and analyze their data occasionally

Psychology: don't mention Freud or ever call them a soft or social science, but make sure you gently remind them that social factors can impact reproducibility and try to keep them from drawing sweeping conclusions about the inherent nature of humanity

Neuroscience: be suitably impressed by their newest experiment and then remind them that people are not mice as often as possible

Computer Science: make sure they take breaks while debugging by limiting their supply of coffee. Nod and smile when they go off on indexing and arrays. Make sure they always have a rubber duck.

Make sure to keep your scientist away from engineers unless they have been properly socialized to interact in a translational household. The most important thing is to remember to hug your scientist on a regular basis and remind them that there is life outside the lab
