The dwarf planets, in order from the Sun
The five dwarf planets the International Astronomical Union recognizes. Astronomers think there are many more far out in the Kuiper Belt and beyond that have not been confirmed.
In 2006 astronomers created a new group, the dwarf planets, for round worlds that orbit the Sun but have not cleared their path of other objects. Pluto is the most famous; one sits in the asteroid belt and the rest are far beyond Neptune.
Five fits in one chunk. Make a first-letter sentence for the order (C, P, H, M, E), for example "Curious Penguins Hike Many Evenings," or better, one of your own. Then give each a picture from its fact: a cereal bowl for Ceres, a heart for Pluto, a spinning football for Haumea, and a goddess with a single moon for Eris.

The dwarf planets, in order from the Sun
| From the Sun | Dwarf planet | Where it orbits | Remember it by |
|---|---|---|---|
| 1 | Ceres | Asteroid belt, between Mars and Jupiter | The first dwarf planet visited by a spacecraft (NASA's Dawn) |
| 2 | Pluto | Kuiper Belt, beyond Neptune | Found in 1930; called a planet until 2006; visited by New Horizons in 2015 |
| 3 | Haumea | Kuiper Belt, beyond Neptune | Spins so fast it is stretched into a football shape |
| 4 | Makemake | Kuiper Belt, beyond Neptune | Found in 2005; has one known moon |
| 5 | Eris | Scattered disk, beyond the Kuiper Belt | About the size of Pluto; its discovery led to the 2006 decision |
