Short and simple. Neptune is a gas planet, and some of that gas is Nitrogen, Hydrogen, and Methane. Maybe you can see where I'm going with this. What would happen someone/something tried to set Neptune on fire?

The nitrogen dimer (it's gas form - about 70% of outside air) is inert. Hydrogen gas (another dimer) and methane are both very reactive, but not with each other. Neither will react with the nitrogen gas.

Unless there are other gasses in that area, big fat nothing will be going on.

EDIT - above post came in as I was posting. Trace amounts of oxygen gas with hydrogen and methane will give you trace amounts of water, methanol, formic acid and formaldehyde.

It won't work because comets and such hit the outer planets literally all the time. Meteors produce WAY more heat via friction than your average match and the planet hasn't gone up in a ball of flames yet.

I won't pretend to be an expert on atmospheric pressures and ideal gas laws ans such, but I'm willing to bet that the pressure on gas planets is the reason why they don't burst into flame.

You need three things for fire: Fuel, Heat, Oxygen

Neptune doesn't have oxygen in a large enough amount to fireball the planet.

Why do you think it's still there? Why do you think it hasn't been burned up by some meteor in the billions of years it's been there?

But sure, it'd make a hell of a firework!

I like your way of thinking there...

Maybe you could get a combustion effect if there was some form of oxidizer (like that in rocket engines). There's a lot of fuel so...

Anyways I really like Neptune and it's probably my favorite planet apart from the one that is begrudgingly keeping me alive right now I'm not exacly keen on blowing it up.

Right! Pluto is now defined as a star....a very cold star.....:p
Not even close to what a star is =P


Anyways, the universe and space has always fascinated me. I want to go to college for something with it, but im not sure what would be profitable to me that deals with astronomy.

Actually ,if I recall correctly, its now a dwarf planet.
actually it's called a plutoid at least according to Neil DeGrasse Tyson, the man who killed Pluto
I still think it should be a large comet.

Obviously Neptune in planning to kill the Earth by exploding upon us, I suggest we attack first all I need is about 10,000 oxygen tanks, a spacesuit, 1 lighter and two small paperclips

Cooler still, Jonathan Coulton made a song about how Pluto has a binary orbit with it's moon Charon, and how due to this orbit, they face each other as they spin, like dancers.

Its mixed into a nitrogen/hydrogen/methan hymogenous mess. Nothing would really happen because nitrogen is not flammable at all. It also has an assload of helium which is not flammable at all. Think about it this way the earth is made of 80 percent nitrogen and 20 percent oxygen. Does the earth blow up whenever someone lights a stove? It holds a flame but does not blow up.
