Brightness of the Sun and Other Stars Notes

Where is the Sun located in our solar system?

• In the center

• On the edge

• Outside the solar system

What is a star?

• A huge ball of hot matter that gives off energy

• A cool ball of matter that absorbs energy

• A gigantic rock in space

• A burning candle floating in space

How does a star shine?

• By the large amounts of energy given off

• By reflecting light from nearby planets

• By absorbing light from nearby stars

• By trapping heat near its surface

Temperature in degrees Fahrenheit of the Sun’s center

• 27,000,000F

List the three main layers of the Sun and their job.

• Core: where the sun’s energy in produced, radiative and convective zones: they carry the energy to the sun’s surface

• Photosphere, Chromosphere, and Corona: they represent the visible surface, the middle layer, and the outer atmosphere of the Sun.

• Umbra, Penumbra, and Corona: these describe parts of sunspots and the outer atmosphere, not the main layers of the Sun.

• Fusional zone, Diffusive zone, and Emissive zone: these are not the recognized primary layers of the Sun.

Three layers of the sun's atmosphere and a fact about each

• Photosphere: the surface of the sun we can see, Chromosphere: the intermediate layer, Corona: can only be seen during a TOTAL solar eclipse

• Photosphere: the surface of the sun we can see, Chromosphere: the surface visible during sunrise, Corona: always visible

• Photosphere: the outermost layer, Chromosphere: the cold layer, Corona: the inner layer

• Chromosphere: the surface of the sun we can see, Corona: the intermediate layer, Photosphere: can only be seen during a TOTAL solar eclipse

The sun appears brighter than other stars in the sky that are actually brighter because it is much closer to Earth.

• It is much closer to Earth

• It is intrinsically brighter

• It has a larger size

• It produces more energy
