•
Centre of our solar system
•
The sun is a star made up of gases – so it does not have a solid surface
•
Does not have any rings
•
Temp. at core is 27 million degrees Fahrenheit
•
orbited by 8 planets, at least 5 dwarf planets, 10 000+ of asteroids, and

100 000+ of comets
MERCURY
•
Closest planet to the sun
•
Smallest planet in our solar system

VENUS
•
2nd closest planet to sun
•
Rocky or terrestrial planet. Also has volcanic landscape
•
No moons and no rings
•
Closest in size to earth in our solar system
•
Temp. is approx. 900 degrees Fahrenheit

EARTH
•

Called an ice giant because of its frozen exterior
•
Like Venus, Uranus spins the opposite direction
•
Also rotates on its side instead of upright
•
Has 27 moons and a faint ring system
•
