Luminous objects are things that generate their own light such as The Sun and Fireflies. Illuminated objects are things that reflect light that has come from another source, things like The Moon or anything in your room when you switch on your light.
Luminous objects are sources that emit light, while illuminated objects are those that reflect or scatter light from a different source.
Two examples of energy transfer by conduction between two objects are when a metal spoon heats up in a hot cup of coffee and when a person's hand warms up when holding a warm water bottle.
The two flames that flicker both non-luminous and luminous are a candle flame and a gas stove flame. When burning normally, these flames emit light due to combustion. However, if they are disturbed or lack sufficient oxygen, they can flicker and may become non-luminous.
Examples of two objects that rub together include rubbing a balloon against fabric to create static electricity or rubbing two sticks together to start a fire.
Two examples of non-contact forces are gravitational force and electromagnetic force. Gravity acts between two objects without direct contact, while electromagnetic force can attract or repel charged objects without physical contact.

The Sun and a lighted candle are luminous.
Luminous - bodies are objects which exhibit their own light.EXAMPLE:-SUNnon-luminous bodies are objects that reflect light from luminous bodiesEXAMPLE:-moonLuminous bodies are insects that give a light, such as the glow worm. Non luminous bodies do not glow o their own. it can also refer to things in space; such as planets, moons and stars

In 99.99%+ of the known cases, planets would be illuminated objects. For a planet to be luminous it would need to provide a source of light beyond reflected light. In theory there might be a planet or two out there that could provide its own light. A few planets in our solar system (Venus, Jupiter, Saturn, Uranus, and possibly Neptune) are known to generate some lightning storms, but those are irregular, localized, and usually low enough in the atmosphere that they don't provide much light visible from the surface. A recently formed planet might glow hot enough to put out a little bit of light, but probably not very much even if it were covered in magma.
The sun is a self-luminous celestial body that emits its own light and heat through nuclear fusion reactions in its core. Fireflies are insects that are self-luminous due to a chemical reaction in their bodies that produces light, often used as a signal for communication and mating.
