  1. Our Solar System Big Idea 5: Earth in Space and Time SC.5.E.5.1, SC.5.E.5.2, SC.5.E.5.3

  2. Planets in Our Solar System • The inner planets of Mercury, Venus, Earth, and Mars are small and mostly solid. The outer planets of Jupiter, Saturn, Uranus, and Neptune are large and made mostly of gases. • Between the inner and outer planets is a belt of rocks called asteroids that orbit the sun. • Comets are icy gaseous objects that leave dust trails when their orbits come near the sun.

  5. Planet Characteristics Inner Planets Outer Planets Size: Large Composed of gas and dust Many moons Temperature: Cool to cold Jupiter Saturn Uranus Neptune Size: Small Rocky and Solid Few or no moons Temperature: Hot to warm . • Mercury • Venus • Earth (one moon) • Mars

  6. Sun • The sun is the closest star to Earth. • The sun is a big ball of hot gases. • The sun gives off two kinds of energy: light and heat. This is called solar energy. • All eight planets orbit, or revolve, around the sun. • The sun is so large that more than a million Earths could fit inside it.

  7. Sun and Stars • Stars come in all different sizes. • Our Sun is the standard used for comparing all other star sizes. • The biggest stars are called supergiants. Some are 500 times larger than the Sun. • Some of the smallest stars are white dwarfs. Many are 1/100 the size of the Sun - roughly the size of Earth

  8. Planet • A planet is a large ball of rock or gas that follows a path round the sun. • There are eight planets. Sun  Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune (My Very Educated Mother Just Showed Us Neptune!)

  9. Thesolar systemincludes the sun and eight planets.

  10. Earth • Earth is the planet that we live on. It is the 3rd planet from the sun. It is called a “Rocky Planet,” because it is made of rocks. • Sometimes Earth is called the “Water Planet,” because it is the only planet with the water we need to live. • Earth orbits, or circles, the sun in 365 days, or one year. • While it is orbiting the sun, it also spins like a top! It spins 1 time in 24 hours, and that is why Earth’s day lasts for 24 hours. • Earth is the only known planet where plants and animals live.
