Trivia: Which galaxy’s name was inspired by “The Lord of the Rings”?

Eye of Sauron
Condor Galaxy
Hoag’s Object
Circinus Galaxy

The correct answer is Eye of Sauron

So why is this answer correct? : Fans of “The Lord of the Rings” trilogy will recognize this ominous name, which was given to spiral galaxy NGC 4151 because of its likeness to the “Eye of Sauron,” a symbol of the Dark Lord in the series. Scientists have spent lots of time researching this galaxy because it is one of the closest galaxies to Earth that has an actively growing supermassive black hole at its center.

Trivia: What is the name of the asteroid belt located just past Neptune?

Europa
Orion’s Belt
Kuiper Belt
Kemble’s Cascade

The correct answer is Kuiper Belt

So why is this answer correct? : The Kuiper Belt is a doughnut-shaped region (similar to the asteroid belt) located just past the planet Neptune. Scientists believe that there could be trillions of comets in this region, and hundreds of thousands of larger icy objects, like dwarf planets. Not much is known about these mysterious worlds in the Kuiper Belt — the first mission to explore the region wasn’t until 2015.

Trivia: What is the closest major galaxy to the Milky Way?

Condor galaxy
Andromeda galaxy
Medusa merger
Sombrero galaxy

The correct answer is Andromeda galaxy

So why is this answer correct? : Andromeda is the closest large spiral galaxy to our home galaxy, the Milky Way. It is 2.5 million light-years from Earth, making it the farthest galaxy that is visible to the naked eye. It was first recorded by French astronomer Charles Messier in the late 18th century, which is why it is also called Messier 31, or M31. In 2012, this galaxy made headlines when NASA announced that in about 4 billion years, Andromeda and the Milky Way will collide.

Trivia: What is the closest star system to Earth?

Aldebaran
Draco
Alpha Centauri
Ursa Minor

The correct answer is Alpha Centauri

So why is this answer correct? : The name Alpha Centauri might sound familiar to fans of “Lost in Space,” where it was a safe haven planet for extraterrestrial travelers. The real-life Alpha Centauri is a triple star system that is closer to Earth than any other star in the galaxy, besides the sun. Alpha Centauri A and Alpha Centauri B are the two largest stars and are 4.35 light-years from Earth. Alpha Centauri C, also known as Proxima Centauri, is 4.25 light-years away.

Trivia: Which planet name was not derived from Greek or Roman mythology?

Earth
Mercury
Uranus
Pluto

The correct answer is Earth

So why is this answer correct? : Earth is the only planet in the solar system not named after a Greek or Roman god. The word “earth” has been around since at least the 15th century, from the Old English term “eorpe,” meaning “ground, soil, dirt, dry land; country, district,” and “the material world, the abode of man,” just as we use it today. “Eorpe” came from the Proto-Germanic term “erþ ō,” which stems from the Proto-Indo-European root “er-,” meaning “ground.”

Trivia: What might you see during a total solar eclipse?

Baily’s beads
Mercury in retrograde
Aurora borealis
Apogee

The correct answer is Baily’s beads

So why is this answer correct? : Baily’s beads are an optical phenomenon seen during total and annular solar eclipses that resemble a string of bright spots. Just before the moon eclipses the sun, a thin crescent of sunlight is broken by irregularities on the moon’s surface, such as mountains and valleys, resulting in the dotted light spots.

Trivia: What was the first asteroid to be discovered?

Artemis
Ceres
Io
Ariadne

The correct answer is Ceres

So why is this answer correct? : Ceres is the largest asteroid in the asteroid belt between Mars and Jupiter, and the first to be discovered in 1801 by Italian astronomer Giuseppe Piazzi. In 2006, the planetary body was considered so large, it was designated as a dwarf planet.

Trivia: What term means the alignment of three or more celestial bodies?

Perihelion
Apastron
Achondrite
Syzygy

The correct answer is Syzygy

So why is this answer correct? : A syzygy occurs when three or more celestial bodies are aligned in a straight line. This can refer to the alignment of the Earth, moon, and sun, which can cause a solar or lunar eclipse, or to an alignment of the planets. Medieval scholars were fascinated with syzygies, as it was speculated that the end of the world would occur when all of the planets were in alignment.

Trivia: How frequently is Halley’s comet visible from Earth?

Every 3 years
Every 15 years
Every 75 years
Every 214 years

The correct answer is Every 75 years

So why is this answer correct? : Halley’s comet is a periodic comet that orbits near Earth about every 75 years. The comet is named after astronomer Edmond Halley, who studied reports of the comet from 1531, 1607, and 1682 and concluded that the observations were all referencing the same recurring comet. The last time the comet was visible from Earth was in 1986, and it is projected to return in 2061.

Trivia: What is NOT a part of a comet?

Nucleus
Stomata
Coma
Tail

The correct answer is Stomata

So why is this answer correct? : Comets are balls of frozen gas, rock, and dust that orbit the sun. They have a frozen core, or nucleus, and when comets approach the sun, the ice sublimates and forms an “atmosphere” surrounding the nucleus, called a coma. As it travels through space, the coma leaves a visible tail. A stomata, meanwhile, refers to a part of a plant.
