Quiz Answer Key and Fun Facts
1. A prominence flows along the magnetic lines of the Sun?

Answer: True

A prominence is a bright cloud of gas projecting from the Sun's chromosphere into the corona. They can be thousands of miles long, and they can last for months.
2. How long has the Sun been in existence?

Answer: 4.5 billion years

The study of chondrules shows our solar system to be about 4.5 billion years old.
3. A plage, like a sunspot, is a cooler darker region on the Sun.

Answer: False

A plage is a bright region that forms in the lower chromosphere and is associated with sunspots.
4. Our Sun is located where in the galaxy?

Answer: 30,000 light years from the center

5. What is the Sun's absolute (not apparent) magnitude?

Answer: 4.8

The Sun's magnitude at a distance of 32.6 light years (ten parsecs) is a plus 4.8. On Earth a sixth magnitude star is about the faintest most people can see with the unaided (no binos or telescope) eye. The Sun's apparent magnitude (from the Earth) is -26.5.
6. Some solar flares are also known as Coronal Mass Ejections (CMEs).

Answer: False

CMEs may be caused by solar flares but they are not the same thing. A CME is an ejection of mass into space while a solar flare is an explosion caused by magnetic reconnection in the sun 's magnetic field.
7. Auroras are more likely to occur where?

Answer: Earth's magnetic poles

Although auroras have been seen at least as south as Texas, they usually occur near the poles.
8. What causes auroras?

Answer: Impact of atomic particles from the Sun

Auroras are caused by the impact of atomic particles from the Sun that are trapped in the Earth's magnetic field.
9. How high up do aurora usually occur?

Answer: 60 miles or higher

Aurora are more frequent during solar maximum, an eleven year cycle of the Sun that is not well understood.
10. The Sun converts 700 million tons of mass each second.

Answer: True

At that rate, it will still take about a trillion years to use only 7 percent of the Sun's mass.
