well the difference is that asteroids are giant rocks floating around and they are part of the asteroid belt. Dwarf planets are bigger and are too big to be an asteroid and too small to be a planet. Did you know that one dwarf planet Ceres is actually one of Jupiter's largest moons!!!! :)
A planet has is own rotation, gravity and atmosphere. A moon revolves around a planet and has no atmosphere. An asteroid is a large space debris moving around. A comet is consistent on mainly forzen ice moving through space at fast speeds.
There is no difference between the name meteor and meteorid and meteorite but the real difference of an asteroid and a meteor is well meteors move really fast around space and an asteroid they just kinda stay there thats why they call it an asteroid field cyndaquil831 is out
