Pluto (if you still consider it as a planet),
They are planets and natural satellites [moons].
Not exactly. An object is called a "moon" if it orbits a planet; not if it orbits the star directly.
A planet or a dwarf planet

A dwarf planet.
No. For one thing, a planet-like object that orbits a planet is a moon, not a planet. Mars does have two moons but they are captured asteroids, and would not be considered planets if the had their own orbits around the sun.
The moon is the closest heavenly body to the earth and because of its relatively high albedo it reflects a lot of the light falling on it hence it is the brightest object in the night sky. Similar reasons also apply to Venus, which is also a very bright object.
They have their own orbits, around the star they formed around, just like how our planet orbits our sun.
Chemosynthetic prokaryotes can make their own food in the absense of light.
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.

Moon
A luminous object can reflect light off other light sources. But it can also produce its own light.
A planetary body is a non-luminous object rounded by it's own gravity that orbits a star or a stellar remnant. A moon, or satellite, orbits a planetary body.
A planet
A dwarf planet.
The light hits its own motion to make its speed
The sun is capable of producing its own light.
Correct. A planet is defined as orbiting a sun. The moon orbits the Earth - so it's a satellite. It doesn't shine under its own 'power' but reflects the light of the sun shining on its surface.It is a non-luminous object
According to the primary level science the object which emit their own light are the luminous object.....
Luminous objects usually give out the light that they make on their own. An example of a luminous object is a star or an LED lamp.
