Minor Planet number 90377 Sedna has never been moved from the asteroid classification. The IAU hasn't received enough data to say it is a dwarf planet because observations to check for things like hydrostatic equilibrium is so difficult for an object in the far out scattered disc section it resides in. Asteroids do not have hydrostatic equilibrium whereas Dwarf Planets do. Sedna may very well qualify as a Dwarf Planet; we just don't know yet.

What is the main difference between a asteroid and a meteoroid?
An asteroid is larger than a meteoroid, though the actual size requirement is not defined.
Where does the asteroid belt sit in the solar system?
Between the orbits of Mars and Jupiter. Also there's the Kuiper Belt after Neptune, and the scattered disk. After that, farther away than Sedna, is the Oort Cloud.
What is the difference between an asteroid and an asteroid belt?
An asteroid is a relatively small object in space composed primarily of rock and/or metal. An asteroid belt is a region in space around a star that has a higher then normal concentration of asteroids.
Where is Sedna?
In between the kuiper belt and the Orrot cloud.
