-- Those are meteoroids.
-- One that happens to encounter Earth's atmosphere and burn by friction causes
a momentary streak of light in the sky called a "meteor".
-- If anything is left of it to reach the ground, the remnant is called a "meteorite".
When they are in space such objects are called meteoroids. When they enter the Earth's atmosphere they becom meteors. If they don't completely burn up but reach the ground, they are called meteorites.
In decreasing order of size, minor planets, asteroids, and meteoroids. If they also have a lot of frozen gas which occasionally vaporizes, we might call them comets.
There are too many to count, even if we could detect all of them - which we can't.

Depending on the size, and some other factors, it may be a meteorite, an asteroid, a moon, or a planet.
they are called meteoroids
Metors or metoriods
An asteroid
The particles of dust and ice that orbit the sun are called comets. They are small solar system bodies which when close enough to the sun, they display a temporary atmosphere.
A comet.
A comet.
A comet that's bound to the sun and appears periodically is in an elliptical orbit. A comet that whizzes through the solar system only once and then leaves for good is in a hyperbolic orbit. If the comet is periodic but with an exceptionally long period ... thousands of years e.g. ... then we can't tell, from the small part of its orbit that we can see, whether it's elliptical or hyperbolic.
A small galaxy with stars and very little dust is commonly called an elliptical galaxy. Elliptical galaxies are extremely small and typically made up of smaller and older stars.

They do not orbit at all. A "meteor" is the glowing streak of light in the sky caused when a space rock penetrates the Earth's atmosphere and is heated to incandescence through friction and compressive heating. The space rock (sometimes called a "meteoroid") is no longer orbiting the Sun, which it HAD been doing; the space rock will either explode, or disintegrate, or fall to Earth. The pieces that fall to Earth are called "meteorites". The pieces that disintegrate are called "dust".
A comet.
The "dust" from a volcano, more properly called ash, consists of tiny pieces of rock and glass blasted out when a volcano erupts explosively.
Pieces of dust or small meteoroids. Smaller than this are the electrons in the solar wind.
there isn't a difference in the gold. The only reason it is called gold dust is because gold dust is very small flakes of gold often found while gold panning. If you get enough gold dust you can have it melted down into a nice bigger nugget. :) Gold dust is fine particles of gold. gold nuggets are naturally occurring pieces of concentrated gold.
"Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets." -NASA
A collection of small rocks or asteroids that gets caught in the planets own orbit. It is also a ring of cosmic dust and other small particles orbiting around a planet in a flat disc-shaped region. The rings are believe to be pieces of comets, asteroids or shattered moons that broke up before they reached the planet. Planetary rings, then, consist of millions of separate small rock and ice particles, each maintaining their own orbit around the host planet.
A comet. ^.^
no, it was lots of small pieces of rock and dust colliding together making large planets, and moons
A dust devil is sometimes called a mini tornado, though it is not actually a tornado, because it looks like a small tornado.
A dust devil is a small long-lived whirlwind which is visible as a column of dust. The Navajo called them as chiindii, ghosts or the spirits of dead Navajos.
