It is a meteor or meteorite depending on whether or not it has entered the Earth atmosphere.It can also be a comet if it is mostly or only frozen materials.
comet
An asteroid-sized chunk of rock with a tail would be a comet.
There are sand-sized rock fragments in the solar system, but when they get to that size they are not considered asteroids. They are called meteoroids.
Size matters All things being equal, size matters. If you have a truck-sized hunk of, say, lead (Pb), it will have more mass than a peanut-sized piece of the same material. But if you have two dissimilar materials, then size can be deceiving. Because materials have different densities, a small object may actually be more massive (that is, it may weigh more) than a much larger object. Shape has nothing to do with mass or weight. +++ To summarise, Mass = Volume X Density.
There are no known asteroids the size of Texas that have even the slightest chance of hitting Earth. The only known Texas-sized asteroid is Ceres, which has a stable orbit in the asteroid belt and could never hit Earth.
Scientist aren't sure yet but they have a theory that a huge comet or asteroid collided with the blue planet causing it to spin on its side.
The most common rocky objects in space are asteroids. An asteroid can range from a small rock to known sizes of hundreds of kilometers in diameter.

A Meteoroid if the chunk is boulder sized or smaller, or just another Asteroid if it is house-sized or bigger.

No. The moon formed after a planet-sized object collided with Earth.
Mars actually has 2 asteroid-sized moons Deimos and Phobos. Does that answer your question?
No. For a star, the sun is 'medium sized', but it's by far the largest single object in the solar system.
The vast majority of the volume of space called the "Asteroid Belt" is just that; space. It's mostly empty, with a very few large bodies, thousands of medium-sized rocks, and millions of small rocks.

Drilling accurate sized holes in a number of materials.
They are called planets >.>
