KOMPAS.com – Before astronomers knew there were celestial bodies Should (Currently), Pluto is known as the ninth planet after Neptune.

However, when astronomers discovered the FY9 2005 celestial body in 2005, it changed its name to Makemake in 2008; Pluto has been excluded from the category of planets in our solar system.

Why? Here are some facts you need to know about makeup:

1. Invention and naming of makemake

Page As reported by the official page NASA, March 31, 2005 by astronomers M.E. Brown, C.A. Trujillo, d.

Before it could be officially confirmed, the sky was named 2005 FY9. Meanwhile, the name Make Make is derived from Rapanui, the fertility god of Easter Island.

Make Make is the smallest planet outside the Solar System and is located on it Kuiper belt (Kuiper Belt), i.e. the area outside the orbit of Neptune.

The Kuiper Belt is a universe of thousands of miniature ice and rocks that formed in the early history of the Solar System 4.5 billion years ago.

Make-up becomes the fourth object of identification Dwarf planet This is one of the reasons why Pluto is losing its status as a planet.

3. The second brightest dwarf planet

Although slightly smaller than Pluto, MakeMake is the second brightest object in the Kuiper Belt visible from Earth.

Pluto is the smartest.

Although astronomers have not been able to see the details of the make-up surface, it is said that its surface is similar to that of Pluto, which is red. Methane and frozen ethane were then found on the surface.

4. Create size and distance

About 444 miles, or 715 kilometers, is the ninth part of the Earth. As an image, if the earth is the size of a nickel, the make-up is the size of a mustard seed.

Make-up is 45.8 astronomical units from the Sun at an average distance of 6,847,000.00 km. Note, the distance from the sun to the earth.

From that distance, it takes 6 hours and 20 minutes for sunlight to reach the make-up.

5. Orbit and rotation

It will take about 305 Earth years for this dwarf planet to orbit the Sun.

Astronomers call the recent journey of the dwarf planet Nigotiona to determine that Makeover has no atmosphere.

Meanwhile, in 2015, astronomers finally discovered a small object (the moon) orbiting Makemake using NASA’s Hubble Space Telescope.

This month is S / 2015 (136472) 1, also known as MK2. It’s 1,300 times duller than make – up.

MK2 is visible at a distance of 13,000 miles or 20,000 km from the dwarf planet, and its distance is estimated to be 50 miles or 80 km.

6. Studies change the history of the solar system

NASA says Makemake has an important place in the history of the study of the solar system because, along with Eris, he was one of the inventors of the International Astronomical Union (IAU) to rethink the definition of planets and create a new group. Dwarf planet.

Reported as follows Space.com, (2/5/2016), in 2006 the International Astronomical Union finally created a new celestial body. “Dwarf planet“Or a dwarf planet.

As a result, they rearranged the definition of planets.

According to Brown, a planet’s orbit is large enough to orbit its own gravity, and nothing else is large enough, as well as its orbital objects are clear.

In this case, Pluto was excluded from the planetary category for not removing debris from its orbit.
