We record the elements present in each unknown astronomical object according to metallicity.

 

  • Moon one - Helium
  • Moon two - Sodium
  • Planet one - Hydrogen -Carbon
  • Planet two - Lithium - Nitrogen

To understand these answers, we need to know what metallicity.

What is metallicity?

In astronomy and physical cosmology, metallicity (also called Z) of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium. Because stars, which make up most of the visible matter in the universe, are composed primarily of hydrogen and helium, astronomers conveniently use the generic term "metal" to describe all other elements collectively.

With this information, we can conclude that we have recorded the elements present in each unknown astronomical object according to metallicity.
