Enceladus
On February 17 and March 9, 2005, the Cassini spacecraft flew by the moon and discovered the moon's faint and thin atmosphere.
Aurora
In Finnish, the aurora is referred to as "revontulet, " which means "fox fire".
The name comes from the legend of an arctic fox that ran north, spreading its tail sparks of fire shining in the moonlight.
Earth
Due to the Earth's rotation, the diameter of the equator is 43 km larger than the polar diameter.
The Earth is therefore a slightly flattened ball - this shape is called a geoid.
Ganymede
The surface of Ganymede is geologically very diverse.
On its surface, there are both geologically young areas and much older, darker, and covered with many craters.

President John F. Kennedy set NASA a goal—to send men to the Moon, and bring them back home safely.
NASA responded to Kennedy’s famous speech, known as “We Choose the Moon,” with the Apollo program (1960-1972).

Earth
The Earth orbits the sun in an elliptical orbit in 365.235 days.
The average distance from the Sun is 150 million km and ranges from 147.09 million km at the periapsis to 152.09 million km at the apsis.
Deimos
The Swift Crater is 1 km in diameter while the Voltaire Crater is 1.9 km in diameter.
They are located close to each other in the northern hemisphere, right near the prime meridian.
Brain
The average weight of a brain ranges from about 1,225 to 1,375 grams.
Men's brains are heavier than women's brains, but the weight does not affect the brain’s performance. An infant's brain weighs only 350 grams.
