I don't think there is a generic name for them. Some such objects in astronomy are:* Planets
* Moons
* Planetoids
* Meteorites
a luminous object
An object that produces its own heat and light energy is called a "self-luminous object." This term is often used to describe things like stars or artificial sources of light that generate their own energy.
The sun is an example of an object that produces its own light through nuclear fusion in its core.
An illuminated object reflects light that came from somewhere else. A luminous object emitts its own light.
The object that shines by its own light is called a luminous object. These objects emit light through a natural process, such as the sun or a star.
We call it 'wingardiem leviosa'
An object that cannot make its own light is called non-luminous. Non-luminous objects do not emit light on their own but can be seen when illuminated by a light source.
The sun is capable of producing its own light.
An object through which light cannot pass is known as opaque.
An object in space that emits its own light and heat is called a star. Stars generate energy through nuclear fusion in their cores, producing light and heat that can be observed across vast distances. The Sun is the most familiar example of a star, providing the Earth with light and warmth.
According to the primary level science the object which emit their own light are the luminous object.....
An object that gives out its own light is called luminous. Examples include the Sun, fireflies, and lightbulbs.
