26Rhea
Rhea, a moon of Saturn, is showing signs of a breathable atmosphere and is a good canidate for an oxygen and water refill station for future missions.
27. The moons of Uranus are the only moons in the universe not given Roman/Greek names, they are given names from Shakespeare's characters.
28. Phobos, Mars's largest moon, is set to collide with Mars or break up into a ring in 50 million years due to tidal forces.
29. One of Jupiter's moons, Callisto, has about 99% of the diameter of the planet Mercury, but only about a third of its mass.
30. It is Venus, not Earth, that has the least orbital eccentricity or most circular orbit in the solar system.

15 Most Controversial & Costly Blunders in History
31Neptune's Moon Neso
Neso, one of the moons of Neptune, is the farthest moon from its planet in the Solar System. It takes 26 Earth years to orbit Neptune planet once and it is as far away from the planet as the Earth is to Venus.
32. Because of Uranus' axial tilt, it "rolls" around the sun like a marble. Its poles each experience 42 years of light and 42 years of darkness during the summer and winter solstices.
33. Raindrops on Saturn's largest moon, Titan (the only other known world with seasonal rainfall) would be twice as big as raindrops on Earth and would fall as slow as snowflakes. Also, they're made of liquid methane, not water.
34. The atmosphere of Venus is so thick that it has 4 times more Nitrogen than Earth even though its Nitrogen only makes up 3.5% of its atmosphere, compared to 78% of Earth's atmosphere.
35. Venus could have had habitable conditions for billions of years in the past, long enough for life to have developed.
36Mercury's Diameter
Mercury's diameter is only 1/194th of that of the sun, as seen from Earth. A telescope with a magnification of 50 to 100x shows Mercury as a small black dot crossing the sun's face during a transit, which will happen again in 2032.
37. The planet Uranus was originally named "George" after the British King George III.
38. Saturn's moon Iapetus was discovered in 2007 to have a unique equatorial ridge that has peaks up to 8 mi (13 km) high and only exists in the dark region of the moon. There is no definitive explanation for how it formed.
39. Mars' moons, Phobos, and Deimos orbit in opposite directions along the equator. At certain longitudes, you wouldn't be able to see them at all.
40. Saturn's largest ring, the Phoebe ring, is so big that if it were visible to the naked eye, it would span the width of two full moons in our sky.
41Mimas
Saturn’s moon Mimas is the smallest known astronomical body to still have a round shape due to self-gravitation. Its total surface area is approximately the same as Spain.
42. Jupiter's moon Ganymede has a thin oxygen atmosphere and also likely has a saltwater ocean 200 km below the surface.
43. Europa's (Jupiter's moons) ocean is 62 miles deep meaning you could fit seven Mount Everest one on top of the other inside it. The deepest part of our ocean, Marianas Trench, could only fit one with 2 miles to spare.
44. The Great Depression was an international event. Between 1929 and 1932, worldwide GDP fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Unemployment in the U.S. rose to 25%, while in some countries it rose as high as 33%.
45. Kraft Foods introduced its boxed macaroni and cheese in 1937 when America was in the throes of the Great Depression with the promise that buyers could feed a family of four for 19 cents. Kraft sold 8 million boxes of its quick-and-easy macaroni and cheese in the first year.
46Popeye The Sailor Man
‘Popeye the Sailor Man’ became so popular during the Great Depression that consumption of spinach increased by 33%. His popularity also led to American children listing spinach as their third favorite food, after turkey and ice cream.
47. Milton Hershey kept his employees working during the Great Depression by having them construct buildings in Hershey, Pennsylvania including a school, arena, and hotel. When a steam shovel was brought in for construction, Hershey told his foreman to get rid of the shovel and hire 40 men instead.
48. During the Great Depression, there was a fleet of "book women" who delivered books, regardless of weather, to rural communities in Appalachia. These women would ride 100-120 miles every week on horseback, traversing dangerous terrain, to ensure that their readers received their books on time.
49. Mr. Goodbar was created in response to the Great Depression. It was marketed as a "meal replacement bar" for lunch and allowed the Hershey company to be one of the only major companies to not lay off a single employee.
50. During the Great Depression of the 1930s, flour manufacturers saw women turning their flour sacks into clothing, diapers, dish cloths, and more, so they started packing their flour in pretty patterns.
