The Sun is a solid ball of fire.
- True
- False
Answer: False
The Sun is not solid; it is a massive sphere of hot plasma (ionized gas). It generates energy through nuclear fusion in its core, converting hydrogen into helium.

The Pole Star (Polaris) is located in the constellation Ursa Minor.
- True
- False
Answer: True
Polaris, the North Star, is the brightest star in the constellation Ursa Minor (the Little Dipper). It is closely aligned with the Earth's rotational axis, making it appear stationary in the sky.

- True
- False
Answer: False
A solar eclipse occurs when the Moon comes between the Sun and the Earth, casting a shadow on Earth. When Earth comes between the Sun and the Moon, it is a lunar eclipse.

Venus rotates on its axis from east to west, unlike most other planets.
- True
- False
Answer: True
Venus has a retrograde rotation, meaning it spins in the opposite direction to most other planets (east to west). This causes the Sun to rise in the west and set in the east on Venus.
Saturn is the only planet in the solar system with rings.
- True
- False
Answer: False
While Saturn has the most prominent and visible rings, Jupiter, Uranus, and Neptune also have ring systems, though they are fainter and less extensive.
A light year is a unit of time.
- True
- False
Answer: False
A light year is a unit of distance, not time. It is the distance that light travels in a vacuum in one Julian year (approximately 9.46 trillion kilometers).
A black hole's gravity is so strong that not even light can escape from it once it crosses the event horizon.
- True
- False
Answer: True
The event horizon is the boundary around a black hole beyond which nothing, including light, can escape the gravitational pull. This is a defining characteristic of black holes.
NASA stands for National Aeronautics and Space Administration.
- True
- False
