Hello, kids. I'm Make Make. I am a dwarf planet.

Scientists discovered me in 2005. I'm smaller than Pluto, and I'm red.

I have no atmosphere. My surface is extremely cold.

I have only one moon. I'm the second brightest Cooper belt object because Pluto is brighter than me.

You can easily see me if you have a telescope.

Hello, kids. I'm Pluto.

Clyde Tumbo discovered me in 1930.

I was the ninth planet in the past, but in 2006, scientists said that I was a dwarf planet

because I was very small. Now, everybody knows that I'm a dwarf planet.

I'm even smaller than the Earth's moon, but I'm bigger than Make Make.

I have five moons. I have a thin atmosphere of nitrogen, methane, and carbon monoxide.
