Sun
TRUE OR FALSE
The Sun is approximately 4.5 billion years old.
TRUE
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.
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.
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.
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.
TRUE OR FALSE
The Sun is primarily composed of oxygen and nitrogen.
FALSE
The Sun is primarily composed of hydrogen and helium.
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.
TRUE OR FALSE
Haumea is perfectly spherical in shape.
FALSE
Haumea has an elongated shape due to its rapid rotation.
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.
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.
What type of star is the Sun?
A) Red giant

C) Yellow dwarf
C) Yellow dwarf
Which planet is known as the "Red Planet"?
A) Mars
B) Venus
C) Mercury
A) Mars
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
Which moon is known as the most volcanically active body in the Solar System?
A) Europa
B) Io
C) Titan
B) Io
What is the effect of gravitational interactions between celestial bodies?
A) Changing color
B) Producing light
C) Changing orbits
C) Changing orbits
What is the hottest part of the Sun?

A) Pluto
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
What shape can orbits be?

C) Circular or elliptical
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.
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.
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.
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.
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.
