The solar system and orbits

What is the solar system?

The solar system consists of the Sun, planets, moons, and other objects bound by gravity.

What is the main component of the solar system?

The Sun, a main sequence star, is the primary component.

How many planets are in the solar system?

There are eight planets in the solar system.

What are the two types of planets in the solar system?

Terrestrial (rocky) planets and gas giants.

What is an orbit?

An orbit is the curved path of an object around a star, planet, or moon due to gravity.

What shape are most planetary orbits?

Most planetary orbits are elliptical (oval-shaped).

What force keeps planets in orbit around the Sun?

Gravity provides the centripetal force that keeps planets in orbit.

How does the speed of a planet affect its orbit?

Faster-moving planets stay in stable orbits closer to the Sun, while slower planets orbit farther away.

What are moons?

Moons are natural satellites that orbit planets.

What are comets?

Comets are icy bodies that develop tails when they approach the Sun.

What is the difference between an asteroid and a comet?

Asteroids are rocky bodies, while comets are icy and develop tails when near the Sun.

How does gravity affect the motion of objects in the solar system?

Gravity acts as a centripetal force, keeping objects in stable orbits.

What is a geostationary orbit?

A geostationary orbit is one where a satellite remains above the same point on Earth.

What is the significance of Kepler's laws of planetary motion?

They describe how planets move in elliptical orbits with the Sun at one focus.

Why is Earth’s orbit important for life?

Earth's stable orbit and distance from the Sun allow for conditions that support life.
