What is Earth’s second moon called?
Cruithne
Its period of revolution around the Sun, approximately 364 days in the early 21st century, is almost equal to that of Earth. Because of this, Cruithne and Earth appear to “follow” each other in their paths around the Sun. This is why Cruithne is sometimes called “Earth’s second moon”.
What are dust moons?
They are cosmic dust clouds first reported in 1961 by Kazimierz Kordylewksi, the Polish astronomer.

Known as Theia, the Mars-sized body collided with Earth, throwing vaporized chunks of the young planet’s crust into space. Gravity bound the ejected particles together, creating a moon that is the largest in the solar system in relation to its host planet.
What are the 3 layers of the Moon?
