TRUE OR FALSE


The Sun is approximately 4.5 billion years old.

TRUE

100

TRUE OR FALSE

Saturn is known as the Jewel of the Planets because of its seven beautiful rings.

FALSE

Saturn has eight main rings, known for their extensive and complex structure.

100

TRUE OR FALSE

Ceres is the closest dwarf planet to the Sun.

TRUE

Ceres orbits within the asteroid belt, making it closer to the Sun than other recognized dwarf planets.

100

TRUE OR FALSE

Ganymede, a moon of Jupiter, is larger than Mercury.

TRUE

Ganymede is the largest moon in the Solar System, larger than Mercury.

100

TRUE OR FALSE

The gravitational pull between two objects is stronger when they are closer together.

TRUE

Gravitational force increases as the distance between objects decreases.

200

TRUE OR FALSE


The Sun is primarily composed of oxygen and nitrogen.

FALSE

The Sun is primarily composed of hydrogen and helium.

200

TRUE OR FALSE

Neptune is the only planet known to rotate on its side.

FALSE 

It is Uranus, not Neptune, that uniquely rotates on its side.

200

TRUE OR FALSE

Haumea is perfectly spherical in shape.

FALSE

Haumea has an elongated shape due to its rapid rotation.

200

TRUE OR FALSE

Comets develop a tail when they get closer to the Sun.

TRUE

The Sun's heat causes the ice in comets to vaporize, forming a visible tail.

200

TRUE OR FALSE

Over time, gravitational interactions can lead to the formation of new celestial bodies.

TRUE

Gravitational forces can cause material to coalesce, forming planets, stars, and other celestial bodies.

A) Mars

B) Venus

C) Mercury

A) Mars

300

Why was Pluto reclassified as a dwarf planet?

A) It is too far from the Sun

B) It hasn’t cleared its orbit of other debris

C) It doesn't orbit the Sun

B) It hasn’t cleared its orbit of other debris

300

A) Europa

B) Io

C) Titan

B) Io

300

What is the effect of gravitational interactions between celestial bodies?

A) Changing color

B) Producing light

C) Changing orbits

C) Changing orbits

400

A) Earth

B) Mercury

C) Venus

B) Mercury

400

Which of the following is the largest dwarf planet?

A) Pluto

B) Ceres

C) Makemake

A) Pluto

400

What is unique about Titan's atmosphere among the moons in the solar system?

A) It contains breathable air

B) It is thick and rich in nitrogen

C) It is completely composed of helium

B) It is thick and rich in nitrogen

400

What shape can orbits be?

A) Always circular

B) Always elliptical

C) Circular or elliptical

C) Circular or elliptical

500

Describe the process of energy production in the Sun.

The Sun produces energy through a process called nuclear fusion. In the Sun's core, hydrogen nuclei combine under extreme pressure and temperature to form helium, releasing a great amount of energy in the form of light and heat.

500

What distinguishes the terrestrial planets from the gas giants in our solar system?

Terrestrial planets, like Earth and Mars, are rocky and have solid surfaces. Gas giants, like Jupiter and Saturn, do not have solid surfaces and are primarily made up of hydrogen and helium.

500

How does the size of Eris compare to Pluto, and where is it located?

Eris is almost the same size as Pluto. Pluto has slightly more volume but less mass. It is located in the scattered disk, a distant area of the solar system beyond the Kuiper Belt.

500

Describe the unique features of Saturn’s moon Titan.

Titan is unique because it is the only moon in the solar system with a dense atmosphere and a liquid cycle similar to Earth’s, with rivers and lakes of liquid methane and ethane.

500

How do gravitational interactions between celestial bodies affect their trajectories?

Gravitational interactions between celestial bodies can alter their trajectories through effects such as gravitational assists, which can accelerate a body and change its path, or by causing distresses in its orbits due to the gravitational pull from nearby objects.
