Question What do we call a group of stars that appear to be together, but are not? (Some may be closer or farther from us.) A special group of constellations that extend out from Earth's equator -sometimes forming outlines in the sky. How far can light energy travel in one year? In space we measure speed and distance relative to how far light energy can travel in one year. We call this a: ______________ Absolute magnitude tell us how much light is given off by a star. Apparent magnitude tells us how bright a star appears to be due to how far or close it is. A large group of stars that are held together by gravity are called a __________________. "Inner Planets" are called 'inner' because they have a rocky core. This planet has daytime temperatures of over 800 degrees F! Mercury does NOT have any atmosphere at all. This planet is called Earth's "sister planet" because it is similar in size. This planet has an atmospheric pressure 90 times greater than Earth's. These two planets have a retrograde rotation.

Multiple Choice 1 15 TERRA = ?? Multiple Choice 1 16 This planet takes more than one Earth year to rotate. That's a LONG day! Earth is the only inner planet to have a moon. This planet is mostly covered with water, and has an atmosphere which is 78% Nitrogen and 21% oxygen. This planet is about half the size of Earth, and about 1.5 times farther from the sun. The surface of the planet is rich in iron ore, which is slowly oxidizing, which causes it to have a red color. PROMINENT = ??

All the gas giants, even though they are made mostly of gases, are likely to have a rocky (or solid) core. Gas giants do NOT have solid surfaces. This gas giant is the largest planet -about 300 times the mass of Earth. This gas giant has the fastest rotation -- about 0.41% relative to Earth. All the gas giants have rings; it isn't just Saturn. This gas giant has a Great Red Spot, which is a giant storm, that is twice as big as Earth. This planet is almost ten times the size of Earth, and almost ten times as far away from the sun, relative to Earth. The two main elements that make up the gas giants are Helium and Hydrogen. This is the second largest planet in our solar system, with 25 moons. This planet has the lowest density of all. If we had a giant glass of water and placed this planet inside, it would actually float in the water!! The rings of Saturn are made mostly of rock, methane, Helium, and Hydrogen. This planet is about 4 times the size of Earth (which makes it one of the smaller gas giants) and 19 times farther from the sun, relative to Earth. The surface of this planet is made up of clouds of blue-green ice crystals of methane and rock. This gas giant has a retrograde rotation. It is one of two planets that have this characteristic. This is the only planet in our solar system to rotate on its side (relative to Earth and all the other planets in our solar system). This gas giant is only about 4 times the size of Earth, but 30 times farther from the sun (relative to Earth). The composition of this planet is pretty much the same as that of Uranus. All of the gas giants are unsuitable for life, as we know it. Pluto has an atmosphere. It's made of methane. A moon orbits a star, a planet orbits a satellite.
