Question 1

True or false: Fomalhaut is located in the constellation Orion, near the hunter's belt.

Accepted Answer

False. Fomalhaut is actually in Piscis Austrinus, the Southern Fish, far from Orion. This mix-up is common due to its bright, solitary appearance.

Question 2

True or false: Fomalhaut is the closest star to Earth after the Sun and Alpha Centauri system.

Accepted Answer

False. Fomalhaut is about 25 light-years away, but many stars are closer, like Barnard's Star (6 ly) and Wolf 359 (7.8 ly).

Question 3

True or false: Fomalhaut's name comes from Arabic, meaning 'mouth of the whale' or 'fish's mouth'.

Accepted Answer

False. It actually means 'mouth of the southern fish' (from Arabic 'Fum al-Hut'), referring to its position in Piscis Austrinus, not a whale.

Question 4

True or false: Fomalhaut is one of the brightest stars in the night sky, ranking among the top 20.

Accepted Answer

True. At magnitude 1.16, Fomalhaut is the 18th brightest star visible from Earth, often called the 'Loneliest Star' for its isolated position.

Question 5

True or false: Fomalhaut is a young star, only about 440 million years old, much younger than the Sun.

Accepted Answer

True. At roughly 440 million years, Fomalhaut is just a fraction of the Sun's 4.6 billion years, making it a prime target for studying planet formation.

Question 6

True or false: Fomalhaut's dust ring is tilted and offset, suggesting gravitational influence from unseen planets.

Accepted Answer

True. The debris disk around Fomalhaut is sharply tilted and misaligned with the star, hinting at a hidden planet or stellar companion shaping it.

Question 7

True or false: Fomalhaut has a confirmed planet that was directly imaged by the Hubble Space Telescope.

Accepted Answer

True. Fomalhaut b was the first exoplanet directly imaged in visible light, though later studies suggest it might be a dust cloud from a collision.

Question 8

True or false: Fomalhaut is part of a triple star system, with two distant companion stars.

Accepted Answer

True. Fomalhaut has two red dwarf companions: Fomalhaut B (TW Piscis Austrini) and Fomalhaut C (LP 876-10), forming a wide triple system.
