Answer: When asteroids enter the atmosphere of Earth or any other planet, they are called meteorites. Typically, asteroids are too small to form a circular shape, unlike dwarf planets or comets.
Explanation:
Why are meteoroids not considered dwarf planets?
Key difference: A dwarf planet is “a celestial body in direct orbit of the Sun that is massive enough for its shape to be controlled by gravitation, but that unlike a planet has not cleared its orbital region of other objects.” An asteroid, on the other hand, is a large chunk of rock that orbits around the sun.
