Depending on size, and some other factors, that can be a planet, a dwarf planet, an asteroid, or a meteor. Depending how you look at it, you might or might not include moons (they orbit a planet, and together, planet and moons orbit the star).
It could be called a planet, dwarf planet, comet, meteor, dust particle.
A black dwarf, I think.
A satellite (or a planet).
Lamp
A planet.
the moon
The bouncing of light is called reflection.
Its an opaque object.
spectrum
There are many objects that no light can pass through, although of course, it depends on what type of light you're talking about. The name of the type of object that visible light cannot pass through is called opaque.
darkness is produced in absence of light darkness is produced in absence of light
Pluto (if you still consider it as a planet),
Reflection
It is our Moon.
They aren't. Stars and moons are two different types of object. A moon is an object that orbits a planet or similar object. A star is a far more massive object that emits its own light.
A luminous object can reflect light off other light sources. But it can also produce its own light.
If light travels through an object, it is still called light. If you want to specify, you might say "light travelling through an object".
No. Any object that is hot enough will produce light, regardless of what heated it.
Heat can not produce light without heating a certain object or material meaning heat by itself cannot produce light on its own.
We call it 'wingardiem leviosa'
A luminous object is an object that can reflect light! examples of these objects are the moon, etc. hope that helped :)
An Object which reflects light is called an illuminous object. e.g) The Moon: Reflects off sunlight
Absorption; the light is absorbed by the object.
