Which of the following statements regarding the Moon is TRUE?

The statement that the Moon is iron-poor is accurate because, in comparison to Earth, the Moon has a significantly lower abundance of iron. The composition of the Moon is primarily made up of silicate minerals, and while it does contain iron, about 10% of its overall composition, this is less than what is found in Earth's crust and mantle.

The other statements do not hold true upon examination. For instance, visible starlight is not the same on the Moon as on Earth due to the difference in atmospheric conditions; the Moon lacks a significant atmosphere, resulting in clearer visibility of stars. Additionally, while the Moon is about one-quarter the diameter of Earth, when considering volume and mass, it is even smaller than that proportion would suggest. The Moon actually takes about 27.3 days to orbit the Earth, rather than the 30 days mentioned.
