What’s In Outer Space? Kristine Benhoff Grade 2 Outer Space • What are some of the things that are in outer space? – – – – – – – Sun Stars Planets Constellations Moon Comets Asteroids The Sun • The sun is a star. • The sun is the largest thing in our solar system. • The sun is in the center of the solar system • The planets revolve around the sun. Mercury • Mercury is the closest planet to the sun. • Mercury is the second smallest planet in the solar system. • The sky is always black because Mercury has no atmosphere to scatter light. • Mercury has many craters and lava-flows. Venus • Venus is the second planet from the sun. • Venus is Earth’s “sister planet.” • 1 day in Venus is like 243 days in Earth! ***Watch Venus Rotate!*** Earth • Earth is the 3rd planet from the sun. • It takes Earth 365.256 days to revolve around the Sun. • Earth is the only planet that is known to have life. • Earth’s atmosphere protects us from meteors which burn up before they hit the surface. Mars • Mars is the 4th planet from the sun. • Mars is known as the “red planet.” • Mars has 2 moons – Phobos – Deimos ***Pack your bags and travel to Mars!*** Jupiter • Jupiter is the 5th planet from the sun • Jupiter is the largest planet in the solar system. • More than 1,000 Earths could fit inside Jupiter! • Jupiter has a “Great Red Spot.” • Jupiter has 16 moons. Saturn • Saturn is the 6th planet from the sun. • Saturn is the 2nd largest planet in the solar system. • Saturn’s day is only 10 hours and 39 minutes long. • Saturn is so dense that if a large enough ocean could be found, it would float in it. • Saturn has rings around it that make it very beautiful. Uranus • Uranus is the 7th planet from the sun. • Uranus has a blue-green color. • Uranus is the farthest planet away from the sun that can be seen with a telescope. • Uranus has 11 known rings and at lest 21 moons. Neptune • Neptune is the 8th planet from the sun. • If Neptune were hollow, 60 Earths could fit inside. • Each season in Neptune lasts 40 years in Earth. ***Color a picture of Neptune!*** Pluto • Pluto is the farthest planet from the sun. • Pluto is the smallest planet in our solar system (smaller than our moon!). • Pluto is a cold, dark, frozen planet. Meteors • A meteor is like a baseball flying at 30,000 miles per hour. • Most meteors are the size of a grain of sand. • A meteor is a metallic piece of debris that travels in outer space. • A meteor is called a “shooting star.” Our Solar System • Because of the different gravity on the planets, we would weigh different on each planet. • Now that you know the order of the planets from the sun, see if you can place them in the right spots.
