Write 3 supporting details you have learned about solar system

Our solar system is a star surrounded by planets that orbit it. Our solar system is away from the center and between the spiral arm of our milky way galaxy.

What is a nebula and where is located?

uA nebula is a cloud of gas

and dust found in

interstellar space.

Explain why planets orbit a star (sun)?

uPlanets are much smaller in mass

pulled in by gravity?

What is a galaxy?

uA galaxy is a grouping of millions

or billions of stars along with

clouds of gas and dust.

Define the following terms with respect to

their composition:

uStar-

ua large celestial body that is

composed of gas and that emits light

uMoon-

ua relatively small spherical body

that orbits a planet

Define the following terms with respect

to their composition:

uUniverse-

uspace and all of the matter and energy in it

uGalaxy-

ua collection of stars, gas, and dust bound

together by gravity

uPlanet-

ua relatively large spherical body that orbits a star

Our solar system consists of eight planets. Which phrase correctly describes a planet?

uA. a large celestial body that is composed of gas and emits light

uB. any one of the primary bodies that orbits a star

uC. many stars held together by gravity

uD. space and all the matter and energy in it

When we say an object is in orbit, we mean

that it is traveling around another object in

space. What do planets in a solar system

orbit?

uA. a star

uB. a moon

uC. a galaxy

uD. a universe

The objects that compose our solar system

vary in size. What is the largest object in our

solar system?

uA. Earth

uB. Jupiter

uC. sun

uD. Earth’s moon

Our solar system consists of eight planets. Each planet is classified as either a terrestrial planet or a gas giant planet. Which is a difference between these two types of planets?

u A. Terrestrial planets are larger than gas giant planets.

u B. Gas giant planets are denser than terrestrial planets.

u C. Terrestrial planets have thinner atmospheres than gas giant planets.

u D. Gas giant planets have rockier crusts than terrestrial planets.

The diameter of Saturn is nearly ten times that of Earth. However, the density of Saturn is much less than that of Earth. What is the reason for this?

uA. Earth is farther from the sun than Saturn.

uB. Saturn has a ring system.

uC. Earth is hotter than Saturn.

uD. Saturn is a gaseous planet.

What is shown in the diagram?

uA.a star

uB.a galaxy

uC.a gas giant

uD.a terrestrial planet

Planets can be classified based on their physical

composition. Some planets are small and dense; other

planets are large and less dense. Which of the following

describes the physical composition of a terrestrial planet?

uA. bright

uB. rocky

uC. liquid

uD. gaseous

Which of these terms would the scientist use

to describe her findings?

uA. a moon

uB. a planet

uC. a galaxy
