* Shape and Density: Asteroids are irregularly shaped, not spherical like Earth. Additionally, they have different densities, meaning the amount of matter packed into a given space can vary greatly.
* No Perfect Fit: Even if we knew the exact volume of 274 Philagoria, you can't perfectly pack spheres (like Earth) into an irregularly shaped space. There would be gaps and wasted space.
Instead of "fitting" Earths, we can compare the asteroid's size to Earth:
* 274 Philagoria's Diameter: Approximately 14 kilometers (8.7 miles)
* Earth's Diameter: Approximately 12,742 kilometers (7,926 miles)
Therefore, Earth is about 913 times larger in diameter than asteroid 274 Philagoria.
