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.

Asteroids are rocky objects that orbit the sun, predominantly found in the asteroid belt between Mars and Jupiter. Sedna is a dwarf planet-like object that lies in the outer reaches of the solar system, beyond the Kuiper Belt. Sedna has a highly elliptical orbit that takes it far from the sun, unlike most asteroids.

Is sedna an asteroid?
No. Sedna is currently classified as a planetoid.
Is planet sedna the closest to the asteroid belt?
no
What is the difference between an asteroid meteorin our solar system?
The difference between asteroid and meteorite is basically the size. Anything more than about 10 m in diameter is called an asteroid.
What is the difference between Pluto and sedna?
Pluto is a dwarf planet in our solar system located in the Kuiper Belt, while Sedna is a trans-Neptunian object with an extremely elongated orbit that takes it far beyond the Kuiper Belt. Pluto is larger and has been visited by a spacecraft (New Horizons), whereas Sedna remains largely unexplored.
What is the difference between an asteroid and a asteroid belt?
An asteroid is a small rocky body that orbits the sun, while an asteroid belt is a region in our solar system located between the orbits of Mars and Jupiter where many asteroids are found. The asteroid belt is like a "belt" of smaller objects orbiting the sun, with the largest asteroid being Ceres.

Which asteroid is the greatest distance from the sun?
90377 Sedna is currently the known asteroid with the greatest distance from the sun, with an average distance of about 80 astronomical units (AU).
What is the difference between Pluto and sedna?
Pluto is a dwarf planet in our solar system located in the Kuiper Belt, while Sedna is a trans-Neptunian object with an extremely elongated orbit that takes it far beyond the Kuiper Belt. Pluto is larger and has been visited by a spacecraft (New Horizons), whereas Sedna remains largely unexplored.
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 is Sedna?
In between the kuiper belt and the Orrot cloud.
What is the difference between meteor meteorid and asteroid?
A meteoroid is a small rock in space, typically smaller than an asteroid. When a meteoroid enters Earth's atmosphere and burns up, it is called a meteor. If a meteoroid survives the atmosphere and lands on Earth's surface, it is referred to as a meteorite. Asteroids are larger rocky bodies in space that orbit the Sun, typically found in the asteroid belt between Mars and Jupiter.
Where does the asteroid belt sit in the solar system?
The asteroid belt is located between the orbits of Mars and Jupiter in our solar system. It is a region where millions of rocky objects, varying in size from small pebbles to large asteroids, orbit the sun. The largest object in the asteroid belt is Ceres, which is classified as a dwarf planet.
