The universe has been around for so long and contains so many millions of objects that it can give us a headache just trying to think about it.

Here are some truly mind-boggling facts

Planets

1. The temperature on Neptune is -214 °C.

2. The temperature on Mercury can reach a whopping 462 °C. However, the side facing away from the Sun may well be covered in ice.

3. Saturn has the most complex magnetic field in the Solar System - its magnetic north pole lies in exactly the same place as its geographical north pole.

4. Storms of high-energy particles in the Sun's magnetotail are so disruptive that they can cause power cuts here on Earth.

5. Mars has the highest volcano in the Solar System, Olympus Mons. This stands at a staggering 27 Km high and 600 km across. Three times the size of Everest.

6. Mars has a gigantic rift valley, the Valles Marineris, that runs for 4000 km. This is made all the more impressive when considering the Grand Canyon is a mere 450 km long!

7. Most of Uranus' 27 moons are named after characters from the works of Alexander Pope and William Shakespeare.

8. Mercury's year is 88 Earth days and its day is 59 Earth days. Consequently, it's the ideal place to take a weekend break in the future.

9. The Sun's gravity is about 28 times that of Earth. This would mean that an 8lb baby on Earth would weigh a whopping 224lbs or 16 stone on the Sun!

10. Neptune was discovered by a French astronomer, Leverrier, and an English astronomer, John Couch Adams, in 1846. They both had difficulty calculating Uranus' orbit and realised that there must be another planet - there was!

11. The Hubble Space Telescope has taken pictures of the surface of Pluto, although it has been noted that trying to observe the surface of Pluto from Earth is as hard as trying to read the writing on a golf ball held 30 miles away!

12. Trans-Neptunian Object Sedna is so far away that if you stood on its surface, you could block the entire Sun with the head of a pin held at arm's length.

I think the fact that women seem to feel permanently cold and can put their hands into dishwater that would take the skin off a human male all point to them coming from a far hotter world than Earth. As Richard Jeni has also pointed out they seem to crave moisture, going by the chemicals they smear themselves in, so there's a real case for them coming from a hot/dried out planet. "They came from a drying planet..."
