Ganymede is the largest moon of Jupiter. It also happens to be the largest moon in our Solar System. Bigger than planet Mercury actually. It was discovered by Simon Marius in 1610, who named it Ganymede, after Zeus' cup-bearer. Its diameter is 5,268.2 km and it takes 7 days and 3 hours for it to orbit Jupiter. Ganymede's distance from Big J is 1.070 million km. Ganymede's core is iron-rich and liquid, it also has an internal ocean, [...]
If you've ever wondered where the actual hell could be located (if it were real), I'm here to tell you it would be in our Solar System. On Jupiter's moon Io, actually. It was named Io (which means "moon" in ancient greek) after one of Zeus' lovers. This little guy is packed with about 400 active volcanoes. In fact, it is the most active (volcanically) body in our Solar System. A total badass! It's a bit bigger [...]
Europa is one of 79 and the 4th largest moon of Jupiter. It was discovered by Simon Marius in 1609, who named it "Europa", after a princess from Greek Mythology. Its diameter is 3121.6km, just a bit smaller than Earth's moon. It takes roughly 3.5 days for Europa to orbit Jupiter. Europa's distance from Jupiter is about 670.900km. Scientists believe that Europa has an iron core and an atmosphere (mostly oxygen). The surface is smooth and icy. Under [...]
The Moon(or Luna) is Earth's only natural satellite. It was created as a result of collision between Earth and Mars-sized protoplanet Teia 4.53 billion years ago. It's 384399 km away from Earth and moves away from our planet at a rate of 3.8 cm per year. The Moon's gravity is 1/6 of Earth's and it has no atmosphere. In 2009 NASA announced that they have found water on the moon. The Moon's cycle is 29 days, 12 hours, [...]
