One might safely say that a turnip is neither luminous nor a planet - but given the astronomical context, it's a safe inference that the subject of interest would be celestial bodies. Some stellar remnants would qualify, one in particular being a black dwarf - which is basically a white dwarf that has cooled down through the brown dwarf phase to a point where it no longer emits radiation (per current calculations, the time taken for this to happen is very long indeed). Other candidates might be a neutron star, or a black hole - in both cases presuming luminosity excludes nearby effects such as highly energetic accretion disks or relativistic polar jets such as are found at active galactic nuclei or quasars (ironically, among the most luminous regions known). Other solar system objects which would qualify would include objects too small to be planets such as asteroids, or others that don't fit the planet definition (such as moons). Although most of these objects could reflect light, strictly speaking, they are not usually themselves luminous.

How can a flashlight can be luminous and nonluminous?
A flashlight can be luminous when turned on, emitting light from the bulb. It can be nonluminous when turned off because at that point it is not emitting any light.
Are light bulbs nonluminous?
Yes, light bulbs themselves are considered nonluminous because they do not produce light on their own. They require electricity to pass through a filament, which then emits light, making the bulb appear luminous.
Can a flashlight be luminous and nonluminous?
No, a flashlight is considered luminous because it generates its own light by converting battery power into light energy. Nonluminous objects do not produce their own light and rely on external light sources for illumination.
What does nonluminous body mean?
A nonluminous body is an object that does not emit light of its own. Instead, it reflects light from other sources, such as the Sun or artificial light sources. Examples of nonluminous bodies include the Moon, planets, and most asteroids.
Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
Is a mirror non-luminous and why?
Yes, a mirror is nonluminous. It does not emit light by itself, it only reflects light emitted by other things.
Why can flashlights be nonluminous?
Flashlights can appear nonluminous if there is a malfunction in the bulb, battery, or wiring. If any of these components are faulty, no light will be emitted even when the flashlight is turned on. Additionally, a depleted or improperly installed battery can also prevent a flashlight from producing light.
