KOMPAS.com – Before astronomers knew that there were square bodies called To (Currently), the ninth planet after Neptune was called Pluto.
However, when astronomers discovered the 2005 FY9 cloud group in 2005, the name was changed to MacMake in 2008; Pluto was extracted from the region of planets in our solar system.
Why is that? Here are some facts you need to know about MacMac:
1. invention and naming of MacMac
Reported by the official NASA page, MacMac was first launched by astronauts on March 31, 2005 at ME Brown, CA Trujillo and D. Found in Robinovitz ‘s Palomer Laboratory.
Prior to its official confirmation, this same cloud group was named 2005 FY9. Meanwhile, the name Makemake came from the name of the fertility god Rabanuy on Easter Island.

MacMake is the smallest planet outside the solar system and is located there Crios Khyber (Khyber belt), ie the area outside the orbit of Neptune.
The Khyber belt is a universe of thousands of small worlds of ice and rocks formed about 4.5 billion years ago in the early history of the solar system.
MacMake is the fourth identified object on the planet Dwarf and causes Pluto to lose its status as a planet.
3. The second brightest dwarf planet
Although slightly smaller than MacMut Pluto, he claims to be the second brightest object in the Khyber belt seen from Earth.
Pluto is elegant at first.
Although astronomers can’t see the details of MacMac’s surface, his surface is similar to Pluto’s surface, which is red. Methane and frozen ethane were then found on the surface.

4. Create scale and distance
With a radius of about 444 miles or 715 kilometers, McMake ‘s radius is the ninth on Earth. For example, if the soil is around the size of a nickel, MacMake is the size of a mustard seed.
At an average distance of 6,847,000.00 kilometers, MacMake is 45.8 celestial units (US) from the Sun. It should be noted that sa is the distance from the sun to the earth.
From that distance, it will take 6 hours and 20 minutes for sunlight to reach the Mac.
5. Orbit and orbit
This deep planet will take about 305 years on Earth to orbit the sun.
Astronomers have recently summoned the occult in front of the star in front of the deep planet to find out if there is a feeling in MacMake.
Meanwhile, in 2015, astronomers finally discovered a small object (the moon) orbiting MacMake using NASA’s Hubble Space Telescope.
This month is S / 2015 (136472) 1 and is nicknamed MK2. It is 1,300 times brighter than the MacMake.

MK2 is visible at a distance of about 13,000 miles or 20,000 kilometers from the deep planet, with an estimated radius of about 50 miles or 80 kilometers.
6. Studies change the history of the solar system
NASA says MacMac has a prominent place in the history of the study of the solar system because, along with Eris, he was one of the engineers of the International Astronomical Union (IAU) who reconsidered his explanation of planets and created a new group. Dwarf planet.
As reported Space.com, (2/5/2016), in 2006 the International Astronomical Union created a new type of square body “Dwarf planet“Or a deep planet.
As a result, they redrawn the definition of planets.
According to the IAU, a planet orbits the sun, but it orbits nothing else, large enough to orbit under its own gravitational pull, as well as destroying the planet. environment around objects.
In this case, Pluto was banned from the planetary region for not removing debris from the orbit.
