E N D
If the Sun is represented by the table, how large do you think the biggest object is going to be? • Share your answer with your shoulder partner.
Using what you know about the size of objects in our solar system, do you think all of the planet models will be able to fit on the table? Why or why not? • Share your answer with your shoulder partner.
Finish this hypothesis statement: “If the Sun is represented by a table cloth, then Earth will be represented by…… because……” • Share your answer with your shoulder partner.
Distance from Sun • Its easier to remember a song or something funny than to memorize the planets order from the Sun. • My Very Excellent Mother Just Served Us Nachos • Mr Valentine Eats Mushy Jumbo Snails Until Noon • That’s an easy way to remember the order! • Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
The Sun • About 99% of all of the Solar System’s mass is located in the Sun. • All the planets could fit into the Sun, and there would still be room to fit more.
Mercury • Closest planet to the Sun • Smallest planet • It is about 1/3 the size of Earth
Venus • Venus is called Earth’s twin because it is so similar to the Earth in both size and mass. • Venus is only a few thousand kilometers smaller in diameter than Earth. • Venus is only similar to Earth in size and mass; everything else is very different.
Earth • Home sweet home! • We are twins with Venus in regard to size and mass. • It would take a jet plane two days to fly around all of Earth. • Our diameter is 12,800 Kilometers. • Third planet from the Sun!
Mars • Mars is a relatively small planet too; it is about half of the size of Earth. • Mars is the fourth planet from the Sun; just past Mars is the start of the Asteroid Belt. • We have rovers on Mars to help us study the planet.
Jupiter • This is our largest planet. • If a jet plane circled Jupiter, it would take 23 days. • Jupiter is more massive than all the planets together. • If you weighed all the planets and compared it to Jupiter, it would weigh less than half of Jupiter.
Saturn • The planet is slightly smaller than Jupiter. • Its mass is less than 1/3 that of Jupiter. • The diameter of Saturn’s rings is about the distance from Earth to the Moon. • Its about 9x the size of Earth
Uranus • Uranus has rings, too! • It is about 4 times larger than Earth. • Uranus is on its side! Its North/South pole points directly into the Sun and directly away from the Sun. • Its mass is about 15 times more than Earth.
Neptune • Its mass is 17 times greater than Earth. • It is our furthest planet from the Sun!
