The Sun is over 300,000 times larger than Earth. Big deal, I'm way bigger than an ant ... even a bull ant.


Light from the Sun reaches Earth in around 8 minutes. Farts reach the nostrils in about 30 seconds.


The Sun’s surface temperature is around 5,500 degrees Celsius (9,941 degrees Fahrenheit). That's hotter than when my wife makes curry.


The Sun loses up to a billion kilograms a second due to solar winds. That's one very effective diet.


Venus is the hottest planet in our solar system with a surface temperature of over 450 degrees celcius. That's not quite as hot as my wife's curry.


Venus is the only planet that rotates clockwise. It's a bit dopey.


The Earth's moon in the fifth largest moon in our Solar System. The four biggest moons in order of size are:

  • Ganymede (Jupiter)
  • Titan (Saturn)
  • Callisto (Jupiter)
  • Io (Jupiter)

Ganymede and Titan are both larger than the planet Mercury! That makes Mercury a little, weeny girl-baby.


The effect of gravity is only about one fifth (17%) as strong on the surface of the Moon compared to the strength of gravity on the surface of the Earth. That's means I could lift more than the Incredible Hulk ... if I was on the moon. 


The Earth’s tides are largely caused by the gravitational pull of the Moon. It could also be caused by a group of elephants jumping into the water at the exact same time.


Footprints and tyre tracks left behind by astronauts on the moon will stay there forever as there is no wind to blow them away ... unless someone wipes them away.


Every year the moon moves about 3.8cm further away from the Earth. I hope they are not considering a divorce.


Each time you see a full moon you always see the same side. That's lucky for us, because the other side is Uuuugly.


Because of its lower gravity, a person who weighs 100kg on earth would only weigh 38kg on the surface of Mars. Women would be very excited about that!


Mars’s volcano Olympus Mons is the biggest in the solar system. It covers the same area as Ireland and is three times higher than our Mount Everest. Some people in England wish it would cover Ireland.


Halley's comet passes the Earth every 76 years (the next time it will return will be 2062). I probably should have taken more interest the last time it came by....


The inner planets of the Solar System are smaller and made mostly of rock and metal. I think I know some people whose heads are filled with rock and metal.


The outer planets of the Solar System are much larger and made mostly of hydrogen, helium and other gases. They are also known as the Gas Giants. I think my youngest son's bottom is a gas giant (although it isn't all that big, there's just seems to be a lot of gas).


There are five dwarf planets: Pluto, Ceres, Eris, Makemake & Haumea. What silly names! They should have been called things like: Mini, Tiny, Shorty, or Junior.


Saturn isn't the only ringed planet. Jupiter, Uranus and Neptune also have rings, they are just less obvious. Our toilet sometimes has rings around the bowl. Am I allowed to say that? My wife will probably get angry. Oh well, I'm not deleting it now. 


The rings of Saturn are made up of millions of ice crystals, some as big as houses and others as small as specks of dust.

My refrigerator has ice blocks.


Saturn is so light, that if you were able to find a pool of water big enough, it would float. Ah yes, but can it swim?


Jupiter is the largest planet in our Solar system. It is so big that more than 1300 Earths could fit inside it. Well, good on Jupiter. But I don't see it sustaining any life, hey?


Jupiter has many storms raging on the surface, most notably the big red spot which is the largest hurricane in our Solar System. It's been raging for over three hundred years. I wonder if Jupiter has ever seen a Mother get really mad - then it would know what a storm really was.


Our Galaxy (the Milky Way) is moving through space at a speed of 1,908,000 km per hour. That's even faster than my sister-in-law drives.


When we look at the stars in the night sky we are staring into history. That's because the light we see from distant stars and galaxies, has taken hundreds, thousands and sometimes millions of years to reach us. Those planets could all be gone now ... that's a bit depressing.


There is no sound in space. But could you still smell a fart?


The first animals to be sent into space were fruitflies in 1947. Only to realise there was no fruit in space.


Recently scientists discovered a planet made entirely of diamond. And what did the scientists called it? Diamond Planet? Gem Planet? No. PSR J1719-1438 b. How can scientist be so smart, yet be so dumb?


The first person to sleep in space was Russian cosmonaut Gherman Titov on August 6, 1961. He was later arrested for falling asleep while operating a vehicle.


There are billions of galaxies in space, each consisting of billions of stars and even more billions of planets. So yeah, of course Earth is the only planet with life on it....
