Pluto is a “dwarf planet” – it is very small. A man discovered Pluto in 1930. Pluto is 7.2 billion kilometers from the earth.
For a long time, we did not have good pictures of Pluto. Now, a spacecraft flies by. It takes great pictures.
There is a video in the Level 3 section. It shows pictures of Pluto. The first picture is old, and it is not good. The last picture is the newest. It is a good picture.
Difficult words: discover (to find), earth (our planet), did (past of “to do”).
