Exploring Our Solar System

What are the main characteristics of inner planets?

• Inner planets are rocky, smaller, denser, have few moons, and are closer to the Sun.

• Inner planets are larger, less dense, and farther from the Sun.

• Inner planets are gas giants with many rings.

• Inner planets have numerous moons and are mostly icy.

Name the four inner planets in our solar system.

• Mercury, Venus, Earth, Jupiter

• Mercury, Venus, Earth, Mars

• Earth, Mars, Jupiter, Saturn

• Jupiter, Saturn, Uranus, Neptune

Which inner planet is known for its extreme temperatures?

• Mercury

• Venus

• Earth

• Mars

What is the primary feature of the outer planets?

• They have no moons or rings around them.

• They are large gas giants with thick atmospheres.

• They are small rocky planets with thin atmospheres.

• They are primarily composed of ice and metal.

How many outer planets are there in our solar system?

• 2

• 6

• 8

• 4

Which outer planet is known for its prominent rings?

• Neptune

• Mars

• Jupiter

• Saturn

What is the average distance of planets from the Sun called?

• Orbital radius

• Planetary distance

• Semi-major axis

• Celestial radius

How do planets orbit the Sun?

• Planets orbit the Sun because of their color and size.

• Planets orbit the Sun in a straight line due to solar wind.

• Planets are pushed away from the Sun by their own rotation.

• Planets orbit the Sun due to the gravitational attraction and their tangential velocity.

What force keeps the planets in orbit around the Sun?

• Magnetic force

• Frictional force

• Gravitational force

• Centrifugal force

How does gravity affect the weight of an object on different planets?

• Objects weigh the same on all planets due to uniform gravity.

• Weight remains constant regardless of the planet's gravity.

• Gravity affects the weight of an object by varying the gravitational force acting on it, leading to different weights on different planets.

• Gravity has no effect on weight across different planets.
