What size object typically transitions from being classified as a meteoroid to an asteroid?
Answer
Larger than about one meter across
The distinction between a meteoroid and an asteroid hinges primarily on size. A meteoroid is generally defined as a small piece of rock or metal orbiting the Sun, usually ranging up to about one meter in diameter. If an object exceeds this size threshold, typically larger than approximately one meter, it graduates in classification and is subsequently referred to as an asteroid. While the boundary can sometimes appear fluid depending on location or context, the one-meter mark serves as the general dividing line for initial classification based on dimension.
