What else can I help you with?
Why planets are not luminous?
because the heat of the crust of the planets is not enough to produce light of its own
What is different about a star from a planet?
Stars are bigger than planets until they finally collapse into dwarf stars. Stars are large enough to produce nuclear energy in their core, so they produce high amounts of heat and light.
What are two ways that planets are different from stars?
1) Although planets can be composed primarily of rock or gas, only stars are objects made of gas that are massive enough to support a nuclear fusion reaction. 2) Although planets and stars can orbit stars (as in binary systems), stars never orbit planets.
What produces its own light while a planet doen't?
A Star will produce its own light, through the nuclear fusion of hydrogen, which releases vast amounts of energy. Planets are not large enough for the required conditions to occur for this reaction, so they don't produce energy in this way.
Was Jupiter a star in the past?
No, Jupiter was never a star in the past. Jupiter is a planet in our solar system, not a star. Stars are massive balls of gas that produce their own light and heat through nuclear fusion, while planets like Jupiter do not have enough mass to sustain nuclear fusion and instead reflect light from the sun.
Why doesn't nuclear fusion occur in the core of planets?
Nuclear fusion requires extremely high temperatures and pressures, which are typically found in stars like the Sun. The cores of planets do not have the same conditions necessary for sustained fusion reactions to occur, so the fusion process is not able to take place there.
Can the moon produce light through internal nuclear combustion?
No. The moon does not produce any light of its own. It only reflects light from the sun. It does not have enough mass to ignite nuclear fusion, nor is it of the right composition. Finally, nuclear fusion and combustion are two completely different processes.
How come only earth has enough air to live on?
because the other planets have different temperatures and do not contain enough Oxygen. I think :P BECAUSE GOD CREATED IT THIS WAY!
How much electricity can a nuclear reactor produce?
Nuclear reactors vary in size the same way any engine does. On the small size, they could produce tens of kilowatts. On the large side they can produce gigawatts. Commercial nuclear reactors that provide power to electrical grids produce about half a gigawatt to about one and a half gigawatts. They do not produce power continuously, even if there are no problems. They have to be shut down periodically for refueling.
How can planets be planets if they are gas planets?
A planet is defined as any celestial body which has enough matter to form itself into a sphere (or spheroid), but without enough mass to begin nuclear reactions. This definition has no relation to what the body is made of, so a gas planet is just as much a planet as one made of rock or one made of styrofoam.
Why doesn't earth make its on light?
Stars produce energy through nuclear fusion. Earth is not massive enough for this to work. Nor does it have lots of hydrogen and helium, i.e. nuclear fuel, for that matter.
How is the different from the planets?
The Sun is a star, which means that it is made up of mostly Hydrogen and has enough mass to carry out nuclear reactions within its core and emit its own light and heat. The planets, even the gas giants, do not have enough mass to burn and glow on their own. There are more differences, but they vary from planet to planet.
