Star properties

Star

• A ball of frozen dust and rock that orbits the sun and has a tail that glows

• A ball of hot gas, primarily hydrogen and helium, that undergoes nuclear fusion.

• A large body in space that orbits a star and does not produce light of its own

Apparent Magnitude

• Temperature of a star

• the true brightness of a star

• the brightness of a star when viewed from Earth

Rotation

• Convection

• when an object turns on its axis

• The movement of an object around another object

Revolution

• The movement of an object around another object

• when less dense material rises and cooler material sinks

• when an object moves on its axis

Corona

• nuclear fusion

• Outermost layer of the sun that can be seen during a solar eclipse

• moves energy of less dense material up and more dense material down

Sun spots

• layer of hot gases

• outermost layer that can be seen during a solar eclipse

• A dark area of gas on the sun's surface that is cooler than surrounding gases.

Prominences

• The middle layer of the sun's atmosphere

• Huge reddish loops of gas

• An eruption of gas from the sun's surface

Solar flares

• An eruption of gas from the sun's surface

• energy moves outward as radiation

• huge loops of gas
