What are heavenly bodies?
Heavenly bodies are natural objects like the Sun, the Moon, and the stars that are seen in the sky.
What is the main role of the Sun in our solar system?
The Sun provides essential heat and light to all the planets, making life possible on Earth.
Why is the Sun visible to us during the day while other stars appear only at night?
The Sun is visible during the day because it is the closest star to Earth, making it appear large and bright, unlike other stars that are much farther away.
How does a Pole Star help in finding directions?
The Pole Star, or North Star, is the brightest star in the northern part of the sky, and by locating it, one can easily determine other directions.
What determines the length of a year on a planet?
The length of a year on a planet is determined by the time it takes for that planet to complete one full orbit around the Sun.
Name the eight planets of our solar system in order of their closeness to the Sun.
The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Which planet has no natural satellite?
Venus is the planet that has no natural satellite.
Why is Earth called a living planet?
Earth is called a living planet because it has the necessary conditions, such as heat, light, air, and water, that make life possible on its surface.
What is special about the volcano Olympus Mons on Mars?
Olympus Mons on Mars is the solar system’s largest volcano, standing three times taller than Mount Everest.
Why is Jupiter also known for having the maximum number of moons?
Jupiter is known for having the maximum number of moons because it has more natural satellites orbiting it than any other planet in our solar system.
What is unique about how Uranus spins around the Sun?
Uranus is unique because it spins around the Sun lying on its sides, unlike most other planets that spin more upright.
Why does Neptune have the worst stormy weather?
Neptune has the worst stormy weather because it is the farthest planet from the Sun, receiving very little heat, which contributes to extreme atmospheric conditions.
What is the difference between natural and artificial satellites?
Natural satellites are heavenly bodies like moons that orbit planets naturally, while artificial satellites are man-made objects launched into space to orbit planets.
How do artificial satellites help us in communication?
Artificial satellites help in communication by transmitting television, telephone, and radio signals across long distances.
Why does the Moon appear to shine when it has no light of its own?
The Moon appears to shine because it reflects the light from the Sun towards Earth, even though it does not produce its own light.
Why can nothing live or grow on the Moon?
Nothing can live or grow on the Moon because it lacks air and water, which are essential for life.
Why do stars, even if bigger than the Sun, look small to us?
Stars, even if bigger than the Sun, look small to us because they are incredibly far away in space.
Name three constellations mentioned in the chapter.
Three constellations mentioned in the chapter are Orion, Great Bear (Ursa Major), and Scorpio.
What is the purpose of mnemonics like “My Very Enthusiastic Mother Just Served Us Nachos” in learning about planets?
