sun
Planets just give off light and heat reflected from the Sun, basically. However
if the planet has an internal heat source it can give off some heat.
Earth and Jupiter are obvious examples.
small body that orbits a celestial body other than the sun
Any star can create it's own light and heat (such as our sun), however the Earth's core is a hot iron core, even though it's a planet.

When any element is excited to the point where it emits visible light, it emits a unique spectrum. The mercury in a florescent lamp emits a spectrum in the ultraviolet spectrum. It excites phosphorus powder on the inside of the bulb. The ultraviolet rays strike the phosphorus and it emits white light. Sodium emits yellow light. Potassium emits purple light. Sodium actually emits two different yellows. Each element emits several different colors.The above is not wrong, but it doesn't really answer the question. I believe the answer the poster was looking for is emission spectrum.You may be correct. I have no intention of giving the emission spectrum of every element. I only wished to help the questioner understand what happens when an emission spectrum is produced. I had the idea that the questioner had the idea that every element produced the same emission spectrum. We interpreted the question differently.
That depends on the type of light bulb in question. Traditional incandescent light bulbs have four main pairs: The filament, which glows and emits light, when electricity runs through it; The inert gas, which keeps the filament from burning; The outer casing, which keeps the inert gas in place; and, The electrical connection, which screws into the socket to provide electricity.
It is released into the atmosphere, but some of it is used later on in cellular respiration
Neon signs give off a characteristic bright red to reddish-orange light. Other colors are created by using argon and mercury, and coating the inside of the tube with phosphors that emit the desired color when ionized. The mercury ionizes and emits ultraviolet (UV) radiation. The UV light slams into the phosphor coating, and the phosphor emits light. The color of that light will be determined by the composition of the phosphor coating.
A large celestial body that is composed of gas and emits light is called a star.

This question answers itself. A star is a large celestrial body made of gas that emits light and the sun is an example of a star
That sounds like the description of a star, except for the part "composed of light". Stars are composed of plasma, which is basically a type of gas.
Neon
Gases emits light. When an electric current is passed through a gas, the gas emits light. For ex. Fluorescent lamps, neon lamps. In case of sun, most of the photons are released from the surface of the sun with wavelength 400 and 700nm, so we are able to see light that the sun emits.
A star emits light because it is hot enough to emit electromagnetic waves in the visible spectrum.
1. The gas surrounding a celestial body. 2. A surroundings influence
I think you are looking for the Photosphere. That is the part of a star that emits visible light.
