Question 1

True or false: VY Canis Majoris is located in the constellation Canis Major, which is named after the mythical dog that hunts Orion.

Accepted Answer

True. Canis Major means 'greater dog' in Latin, representing one of Orion's hunting dogs in Greek mythology.

Question 2

True or false: VY Canis Majoris appears reddish because its surface temperature is cooler than the Sun's.

Accepted Answer

True. At about 3,500 K, it's much cooler than the Sun's 5,778 K, giving it a distinct red hue.

Question 3

True or false: VY Canis Majoris is so large that if placed in our solar system, its surface would extend past Jupiter's orbit.

Accepted Answer

True. This red hypergiant has a radius roughly 1,420 times the Sun's, indeed engulfing Jupiter if centered on the Sun.

Question 4

True or false: VY Canis Majoris is the most massive star ever discovered in the universe.

Accepted Answer

False. It's only about 17 solar masses; far less massive than stars like R136a1, which exceeds 200 solar masses.

Question 5

True or false: If you flew around VY Canis Majoris at the speed of light, it would take over 8 hours to complete one lap.

Accepted Answer

True. With a circumference roughly 8.9 light-hours, a light-speed trip around its equator would indeed take over 8 hours.

Question 6

True or false: VY Canis Majoris will eventually explode as a supernova, but only after turning into a neutron star first.

Accepted Answer

False. It will go supernova directly; neutron stars form from the collapsed core after the explosion, not before.

Question 7

True or false: VY Canis Majoris is actually a binary star system with a small companion star orbiting close to it.

Accepted Answer

False. No confirmed companion exists; it's considered a single supergiant star, though some studies suggest possible faint neighbors.

Question 8

True or false: VY Canis Majoris is losing mass so rapidly that it could form a new ring system around itself.

Accepted Answer

False. It sheds material through powerful stellar winds, but no ring system—just an expanding nebula of gas and dust.
