Some meteorites probably were in the cores of asteroids, once. A meteoroid is a space rock traveling through space, while a meteor is the brief streak of light caused when a space rock hits the Earth's atmosphere. Many meteors burn up completely or explode high in the atmosphere, while some survive to strike the Earth.
Where do the meteoroids come from? Some are probably leftovers from the formation of our solar system. Others may be rocks blasted into space from explosions caused by asteroid impacts on the Earth, or Venus, or Mars, long ago. At least one meteorite found on Earth has been identified as Martian in origin, and other meteorites may have been left over from the time 4 billion years ago when another planet collided with the proto-Earth and formed the Moon!
Asteroids do occasionally collide, breaking into smaller rocks, and it is likely that at least a few of those chunks eventually find themselves falling into the Earth's gravitational well.
That is called a meteorite. It is basically the same thing as an asteroid, but anything smaller than about 10 meters is called a meteorite.
The difference between asteroid and meteorite is basically the size. Anything more than about 10 m in diameter is called an asteroid.
An asteroid is space debris made up of rock and metal and can range drastically in size. When an asteroid makes a collision course for Earth, it is called a meteor. A meteor that manages to hit the Earth is called a meteorite.
There is currently no known imminent threat of a significant meteorite or asteroid impact on Earth. Efforts are being made by scientists and space agencies to monitor and study near-Earth objects to prevent any potential collisions in the future.

chunks of the core of a larger asteroid that was shattered by a collision.

Neither, Jupiter is a planet.
It could perhaps be called an asteroid.
It is simply referred to as the Chelyabinsk meteorite.
A meteorite is an asteroid that is pulled into the Earth's atmosphere.
I think it becomes a meteor in our atmosphere & a meteorite when it strikes.

It is called an asteroid if it has more than about 10 meters diameter. Smaller objects are called meteorites.
Technically, if it hits the Earth it's not an "asteroid", it's a "meteorite". And yes, meteorites hit the Earth all the time.
