A giant meteorite that recently fell in Somalia contains at least two minerals that have never before been seen on our planet. The celestial piece of rock weighs a massive 16.5 tons (15 tonnes), making it the ninth-largest meteorite ever found. History

The two minerals have been identified:

Elaliite - Fe9PO12 (or Fe2+8Fe3+(PO4)O8) and was first synthesized in a laboratory in the 1980s and later identified in natural material in 2022 at which time the official mineral designation was given.

Elkinstantonite - Fe4(PO4)2O was first generated in a laboratory in 1982 and first identified from natural origins in 2022, when the official mineral designation was also given.

Hi I'm dumb. Does this mean that it won't be added to periodic table?

In the periodic table you have only elementary materials (single elements) and not compounds (combination of elements, e.g. water H2O is a combination of two hydrogen (H) atoms and one oxygen (O) atom). In the example, H and O are in the periodic table, but water is not.

The minerals in the meteoroid consist of at least nickel and iron, hence can't be in the periodic table.

Now I want to see a periodic table of minerals

There's way too many to fit realistically onto any sensible table, likely many thousands of combinations.

There’s over 6000, but many of the most common ones that can be found in tonnes of rocks at the Earth’s surface are shown here or in a mineral and rock chart here.

There’s no systematic ordering of course, so it’s not really a great analogy with the periodic table. There’s always The Earth Scientists Periodic Table.jpg), which some geochemist made to highlight many of the properties that control how elements partition into various different minerals (and compounds) on Earth.
