No. Neptune is not nearly massive enough to sustain any sort of nuclear reaction akin to the Sun. It simply does not have enough mass.
Not compared to earth!
No. Neptune's atmosphere is almost entirely hydrogen and helium with small amounts of methane. There is no oxygen.
Yes, in fact, it is the third-largest moon on Neptune, and is commonly referred to as Neptune II.
The names of Neptune's seas, or large dark spots, are: The Great Dark Spot The Dark Spot The Scooter The Small Dark Spot
yes, the planet Neptune includes water in all the gases on the planet, like methane, ammonia, helium and hydrogen.
small
Because you create a pop! It is done by placing a glowing splint into the area. It will ignite the hydrogen and create a pop. It is only done with small quantities, not large ones.
Neither. It is large.
It is a giant.
Not compared to earth!
Not unless a small amount of energy (e.g. an electric spark) is added to ignite the mixture, then the reaction explosivelyproduces hot water vapor (i.e. steam).
No, a piezoelectric crystal generates an electrical current when compressed, but it does not produce enough heat to ignite gunpowder on its own. Gunpowder ignition typically requires a small spark or flame with sufficient heat to initiate the combustion process.
No, Neptune is a planet. Stars are hot, glowing with the heat from nuclear fusion in their core. Neptune is cold, and much too small to have fusion.
No, it is one of the larger planets.
Neptune has no solid surface to land on although it may have a small rocky core.
It is one of the four outer giants, Jupiter, Saturn, Uranus and Neptune.
Neptune is primarily comprised of hydrogen and helium, with small amounts of methane, water and ammonia. This makes Neptune one of the gas giants of the Solar System.
