  4. The solar system is around 4.6 billion years old. Scientists estimate that it will probably last another 5,000 million years.
  5. Enceladus, one of Saturn’s smaller moons, reflects some 90% of the sunlight, making it more reflective than snow.
  6. The highest mountain known to man is the Olympus Mons, which is located on Mars. Its peak is 15 miles (25 km) high, making it nearly 3 times higher than Mount Everest.
  7. The Whirlpool Galaxy (M51) was the very first celestial object to be identified as being spiral.

  22. Our moon is around 4.5 billion years old.
  23. There are more volcanoes on Venus than any other planet within our solar system.
  24. Uranus’ blue glow is down to the methane in its atmosphere, which filters out all the red light.
