A 5 mm object is quite small but still visible to the naked eye. To help you understand its size, I will compare it to some common objects:
- Eraser on the end of a pencil: This can vary, but it is typically around 7 mm wide. Therefore, a 5 mm object would be a bit smaller than this.
- Sesame seed: Sesame seeds can be around 3-4 mm in size, so a 5 mm object would be just a bit bigger than a sesame seed [4].
- Standard piece of rice: A grain of rice is about 5-6 mm long, so a 5 mm object would be roughly the size of one [5].
- Around three stacked U.S. pennies: U.S. pennies have a thickness of 1.52 mm, so three of them would be 4.56 mm [6]. Therefore, a 5 mm object would be slightly larger than three stacked pennies.
