Dwarf Planets 1: Makemake

The only photo of Makemake which has taken by HST

Makemake is the second brightest known object in the outer solar system, just slightly dimmer than Pluto. Its average distance from the Sun is 45 AB (150 million kilometers).

It was discovered by Mike Brown and his team on March 31, 2005… Interestingly, the discovery of Haumea (by the Spanish team) and Makemake with Eris (27 July-29 July 2015) was announced two days apart…

Makemake's diameter is about 1450-1550 kilometers.

In this case, Makemake is the third-largest dwarf planet after Pluto and Eris in the order of magnitude.

Due to its location, Makemake is known as a Kuiper Belt Object or a Trans-Neptunian Object. Makemake was discovered in 2005 by Mike Brown and his team at Caltech University.

Makemake takes 309 years to orbit around 38.6 AU at its closest point and 52.8 AU at its furthest point. One revolution around its axis is about 7.8 hours.

Also, it has a moon!

In April of 2016, observations using the Hubble Space Telescope‘s Wide Field Camera 3 revealed that Makemake had a natural satellite – which was designated S/2015 (136472) 1 (nicknamed MK 2 by the discovery team). It is estimated to be 175 km (110 mi) km in diameter and has a semi-major axis at least 21,000 km (13,000 mi) from Makemake.
