This picture, courtesy of NASA, our national space program, is an artist's rendering of the planned Space Launch System as a rocket lifts off with the Orion spacecraft atop. The Orion spacecraft is already built and ready at Cape Canaveral in Florida. The Space Shuttle program provided successful low-Earth orbit missions, but NASA's heavy-lift launch vehicle will provide a new capability for human exploration beyond low-Earth orbit. The Space Launch System, shown here with Orion on it, is designed to be flexible for launching spacecraft for crew and cargo missions that will go far beyond to the moon again, to explore asteroids, and even to go to Mars. It will be people who are your age right now, maybe even you, who will be the ones to go on these exciting missions.
Talk about these questions in your group:1. How is our view of our Sun different from our view of other stars?2. How and why does the moon's appearance change over the course of a month?3. Why do the positions of the moon, stars, and planets change in the night sky?
Our solar system is located in a galaxy known as The Milky Way.
What is a Galaxy?A galaxy is a group of solar systems, dust, and gas held together by gravity.

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
pp. 167-168
What do we know about the Sun? Click on SC.3.E.5.2; SC.3.E.5 Sun - Size and Appearance
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.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Inquiry 10: Modeling the Solar System(SC.5.E.5.3)
Student Resource pp. 173-181
Question: How can we model the distances of planets from the Sun and from each other?Make a Prediction:In a model of the solar system, the Sun and Mercury (the closest planet to the Sun) are 14 inches apart. How far do you think it is from the Sun to the farthest planet, Neptune? 120 inches 90 feet 300 feet
How are the Planets grouped? What characteristics do they share?

How does Earth differ from other planets?
Earth is the 3rd planet from the sun. It is called the “Rocky Planet,” because it is made of rocks.
Sometimes Earth is called the “Water Planet,” because about 70% of its surface is covered with the water.
Earth orbits or revolves around the sun in 365 days, or one Earth 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.
It has one moon. SC.4.E.5.4
