What is a dwarf planet?

Back

A dwarf planet is a celestial body that orbits the Sun, has a nearly spherical shape, but has not cleared its neighboring region of other objects.

Front

What criteria does a planet need to meet to be classified as a planet?

Back

1. It must orbit the Sun. 2. It must have a nearly spherical shape. 3. It must have cleared the neighborhood around its orbit.

Front

What is the Asteroid Belt?

Back

The Asteroid Belt is a region of space between the orbits of Mars and Jupiter where many small rocky bodies, known as asteroids, are found.

Front

What is the difference between inner and outer planets?

Back

Inner planets (Mercury, Venus, Earth, Mars) are rocky and closer to the Sun, while outer planets (Jupiter, Saturn, Uranus, Neptune) are gas giants and farther from the Sun.

Front

What are moons?

Back

Moons are natural satellites that orbit planets. They can vary in size and composition.

Front

How does gravity affect the orbits of planets?

Back

Gravity is the force that keeps planets in orbit around the Sun, as well as moons in orbit around their planets.

Front

What is the significance of Jupiter's moons?

Back

Jupiter has over 60 moons, which provide insights into the formation of the solar system and the dynamics of celestial bodies.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two masses toward each other, such as the Sun and a planet.

Front

What happens to gravitational force if the distance between two objects decreases?

Back

The gravitational force increases as the distance between the two objects decreases.

Front

What is the role of the Sun in the solar system?

Back

The Sun is the central star of the solar system, providing light and heat, and its gravitational pull keeps the planets in orbit.
