What planets in our solar system are considered ice giants?

 

Uranus and Neptune

(Gas giants are Jupiter and Saturn)

What planet's unique rotation causes it to experience "seasons" that last decades due to its highly tilted axis?

Uranus - tilted at 98 degrees. This extreme tilt results in one hemisphere facing the Sun continuously for about 42 years while the other is in darkness, creating prolonged "summer" and "winter" seasons.

What is the event horizon on a black hole?

The event horizon is the boundary surrounding a black hole beyond which nothing can escape, not even light. It marks the point where the escape velocity equals the speed of light.

100

What is the habitable zone?

The habitable zone, also known as the "Goldilocks Zone," is the region around a star where conditions might be just right for liquid water to exist on a planet’s surface. It’s neither too hot nor too cold, allowing for potential life-supporting conditions.

What galaxy will our galaxy collide with in 4.5 billion years?

(Bonus 100 points: What will the merged galaxy probably be called?)

Andromeda / M31 galaxy

Milkomeda/Milkdromeda

What two elements are stars mostly made of?

Where do we find the oort cloud?

a theoretical, spherical shell of icy bodies that surrounds the solar system at a great distance, far beyond the orbit of Pluto. It is believed to be the source of long-period comets that enter the inner solar system.

Which is the largest moon of Saturn?


(Bonus 100 points: What is the largest moon in the solar system?)

Titan - It has a dense atmosphere and surface lakes and rivers of liquid methane and ethane. 

Ganymede - Jupiter, larger than the planet Mercury, only about half of Mercury's mass. Unique as it is the only moon known to possess a substantial magnetic field and is believed to have a subsurface ocean of liquid water beneath its icy crus
