Hubble just detected an orbital companion around Makemake.

Quote
Peering to the outskirts of our solar system, NASA's Hubble Space Telescope has spotted a small, dark moon orbiting Makemake, the second brightest icy dwarf planet — after Pluto — in the Kuiper Belt.

The moon — provisionally designated S/2015 (136472) 1 and nicknamed MK 2 — is more than 1,300 times fainter than Makemake. MK 2 was seen approximately 13,000 miles from the dwarf planet, and its diameter is estimated to be 100 miles across. Makemake is 870 miles wide. The dwarf planet, discovered in 2005, is named for a creation deity of the Rapa Nui people of Easter Island.

If MK 2 will be implemented in the future, we should wait until has a proper name and until we know more about its orbit. We know almost nothing about its orbital period or mass. I heard about this yesterday, but I am out of a computer for the week. This is exiting. Anyone thinking of potential names?

I think it should be named Tangata or Manu becuase https://en.wikipedia.org/wiki/Tangata_manu is a mythological figure from the same tribe that has a figure called Makemake.

It's orbit most probably is circular and have zero inclination in relation to Makemake's equator. Further observation could give us a value of it's inclination in relation to view direction (thus obliquity of Makemake's rotation axis) and period (thus mass of the planet+moon system).

We'll never know what? The name of Makemake's moon? Yeah we will, it will probably get one in a few years.
