NASA says asteroids range from 33feet to 329 miles in diameter.
I believe a 3 feet diameter object is a meteor not an asteroid.
Rocks in outer space smaller than planets or moons are asteroids.
An asteroid on an orbit taking it near enough to the Sun so that it ignites and leaves a streaming trail is a comet. Comets are normally much larger than asteroids and seem to have a different point of origin than asteroids.
Rocks that hit Earth’s atmosphere and burn up producing a long tail are meteors.
What doesn’t burn up and makes it to the surface of Earth is a meteorite.
Before it was reclassified as a dwarf planet, Ceres was an asteroid 939 miles in diameter
Exactly. I was wondering why they used “asteroid” instead of “meteor” in this article.
