136472 Makemake and its moon, as seen by the Hubble Space Telescope

Makemake (symbol 🝼;^[1] officially known as 136472 Makemake) is a dwarf planet. It was discovered on March 31, 2005 by astronomers Michael E. Brown, Chad Trujillo and David Rabinowitz. It was announced as a dwarf planet on June 11, 2008, and the discovery of a moon was announced on April 26, 2016. Makemake is a Trans-Neptunian object, because it orbits the Sun further out than Neptune.

Originally the object was given a codename 'Easterbunny' as it was discovered shortly after Easter.^[2] The International Astronomical Union gave it the name 136472 Makemake, the creator god of the ancient Easter Island people, to keep its connection with Easter.^[3]

Makemake appears to be made mainly of ice and rock. However, at its very low temperature, ice is as hard as many types of rock.

In 2016, it was discovered that Makemake has a small moon.^[4] Makemake's moon does not yet have a name. Instead, astronomers call it "S/2015 (136472) 1" and use a nickname of MK2. Its orbital period around Makemake is more than 12 days. The moon is about 87.5 kilometers across.

Notes:
Details on the new coding for clickable images is here: [1]
The smaller planets have a bit of an overlap just to ensure they're locatable, especially in the belts.
While it may look strange, it's important to keep the codes for a particular system in order. The clickable coding treats the first object created in an area as the one on top.
- I've placed moons on "top" so that their smaller circles won't disappear "under" their respective planets or dwarf planets.
The "poly" code would be more appropriate for the moons of Jupiter, Saturn, and Uranus. However, there appears to be a bug with that aspect of the code.
- I've compensated by using oversized circles for those moon groups, and tucking them UNDER their planets for now.
The Sun is a rectangle as that approximates the edge closely enough for the purposes of this template.
I've guessed as to the boundaries for the KB, SD, and OC - if they need adjustment, load the image into Paint and use the pencil tool to find the appropriate coordinates.
