13. DWARF PLANETS is in orbit around the Sun
has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape,
has not cleared the neighbourhood around its orbit, and is not a satellite.

14. Previously considered a planet, Pluto was reclassified as a dwarf planet in 2006
2,372 km in diameter
One year on Pluto is approximately 246 years on Earth
Has 5 moons – Charon, Hydra, Nix, Kerberos, and Styx
Pluto

15. Asteroids and comets
A comet is icy and releases a trail of gas or dust. Comets are made of dust, ice, carbon dioxide, ammonia, methane, etc.
Asteroids are small rocks orbiting the sun – though some can get quite large. They are not spherical in shape

16. Comet Halley Named after British Astronomer
When this comet's orbit approaches the Sun, its 15-km (9-mile) nucleus sheds about 6 m (7 yards) of ice and rock into space,
Comet Halley will return to the inner Solar System in the year 2061.

17. THE ASTEROID BELT Located between Mars and Jupiter
Majority of asteroids in our solar system are found here – contains billions of asteroids
Some are very large, some are size of pebbles
One asteroid – Ceres –is considered a dwarf planet. It is the closest dwarf planet to the sun.
