Questions and Answers
- 1.
What is a large object that orbits a star?
- A.
Planet
- B.
Comet
- C.
Galaxy
- D.
Satellite
Correct Answer
A. PlanetExplanation
A planet is a large object that orbits a star. It is a celestial body that is not a satellite of another planet or a moon of a planet. Planets are held in orbit by the gravitational force of the star they orbit. They are generally spherical in shape and do not produce their own light, but instead reflect the light of their star.Rate this question:

Which of these is an inner planet?
- A.
Neptune
- B.
Pluto
- C.
Mars
- D.
Jupiter
Correct Answer
C. MarsExplanation
Mars is considered an inner planet because it orbits closer to the Sun compared to the outer planets like Neptune and Jupiter. Inner planets, also known as terrestrial planets, are primarily composed of rock and metal and have solid surfaces. They are also smaller in size compared to the gas giants like Jupiter. Mars fits these characteristics as it is a rocky planet with a solid surface and is located within the asteroid belt, closer to the Sun.Rate this question:

- 3.
The outer planets are ___________ than the inner planets.
Correct Answer
colder
larger
biggerExplanation
The outer planets are colder than the inner planets because they are located farther away from the Sun, receiving less heat and light. Additionally, the outer planets are larger and bigger than the inner planets in terms of size and mass. Their larger size allows them to have stronger gravitational forces and more extensive atmospheres.Rate this question:
- 4.
The inner planets have ________ moons than the outer planets.
Correct Answer
Explanation
The inner planets have fewer moons than the outer planets. This is because the inner planets, also known as terrestrial planets, are closer to the Sun and have a smaller gravitational pull compared to the outer planets, also known as gas giants. The gas giants have a larger mass and stronger gravitational pull, which allows them to capture and retain more moons in their orbit.Rate this question:
- 5.
The outer planets are made mostly of gases.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The outer planets, also known as gas giants, are primarily composed of gases such as hydrogen and helium. These planets, including Jupiter, Saturn, Uranus, and Neptune, have thick atmospheres and lack a solid surface. Their composition is different from the inner planets, which are primarily rocky. Therefore, it is accurate to say that the outer planets are made mostly of gases.Rate this question:

Ursa Major is another name for the _______ ________.
Correct Answer
Big DipperExplanation
Ursa Major is another name for the Big Dipper. Ursa Major is a constellation that is commonly referred to as the Big Bear, and it contains the recognizable asterism known as the Big Dipper. The Big Dipper is a group of seven stars that form a distinct shape resembling a ladle or a saucepan. It is one of the most well-known and easily identifiable star patterns in the night sky, and it is often used as a navigational tool or a guide to find other celestial objects.Rate this question:
- 10.
Saturn is the only planet to have ________ visible from Earth when looking through a telescope.
Correct Answer
ringsExplanation
Saturn is the only planet in our solar system that has visible rings when observed through a telescope. These rings are made up of ice particles, rocks, and dust, and they encircle the planet. The rings of Saturn are one of its most distinctive features and can be easily observed from Earth. No other planet in our solar system has such prominent and visible rings, making Saturn unique in this aspect.Rate this question:
