A ______ is a hot, glowing sphere of gas that is undergoing gravitational collapse.

• Protostar

• Black Hole

• White Dwarf

• Neutron Star

What is an exoplanet?

• A hot, glowing sphere of gas

• A planet outside our solar system

• The reddening of starlight passing through interstellar dust

• A cloud of gas and dust in space

Which type of Nebulae is found when a very hot star is present nearby and excites a large portion of nebula gas causing to emit light?

• Emission Nebulae

• Reflection Nebulae

• Dark Nebulae

• Plasma Nebulae

A Reflection Nebula can be visually differentiated from an emission nebulae because it...

• appear as pinkish red

• appears bluish in color

• appears dark

• appears greenish yellow

A Dark Nebula is a type of nebula that differs from other types of nebulae in that it:

• emits its own light.

• reflects light from nearby stars.

• blocks light from objects behind it.

• is formed from ionized gases.

Which type of stellar cluster is shown in the image

• Open Cluster

• Nebula Cluster

• Globular Cluster

• Associations

To determine a planet's density, we need to know its:

• mass and volume

• temperature and pressure

• distance from the sun

• orbital speed
