The Solar System By Julie Dort
The Solar System • Our solar system consists of: the sun • the nine planets (and their moons) • It also has an asteroid belt, and many comets and meteors.
The Moon • The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust. • The moon dust is called regolith.
SUN • Our sun is a star located at the center of our solar system. • It is a huge, spinning ball of hot gas and nuclear reactions that lights up the Earth and provides us with heat.
Mercury • Mercury is the planet closest to the sun in our solar system. • It is small, rocky planet has almost no atmosphere.
VENUS • Venus is the second planet from the sun in our solar system. • It is the hottest planet in our Solar System.
EARTH • The Earth is the third planet from the sun in our solar system. • It is the planet we evolved on and the only planet in our Solar System that is known to support life.
MARS • Mars is the fourth planet from the sun. • It is about half the size of Earth. • It has a dry, rocky surface and a very thin atmosphere.
JUPITER • Jupiter is the fifth and largest planet in our solar system. • This gas giant has a thick atmosphere, 17 moons, and a dark, barely-visible ring.
SATURN • Saturn is the sixth planet from the sun in our solar system. • It is the second-largest planet in our solar system.
URANUS • Uranus is the seventh planet from the sun in our solar system. • This huge, icy planet is covered with clouds and is encircled by a belt of 11 rings and 18 moons.
NEPTUNE • Neptune is the eighth planet from the sun in our solar system. • This giant, frigid planet has a hazy atmosphere and strong winds.
PLUTO • Pluto is the ninth and usually the farthest planet from the sun in our solar system. • It also the smallest planet in our solar system and the last to be discovered.
COMETS AND ASTEROIDS • A comet is a small, icy celestial body that orbits around the sun. It is made up of a nucleus, a gaseous coma and a tail. • The tail can be up to 250 million km long. • Asteroids are rocky or metallic objects, most of which orbit the Sun in the asteroid belt between Mars and Jupiter
