The Solar System Flashcards
To Be Able To Know And Describe Different Planets In Our Solar System (9 cards)
State what is meant by a Solar System.
A Solar System is a collection of eight planets and their moons in orbit around the Sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.
Name the planets of our Solar System.
The planets of our Solar System are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Categorize the planets based on the properties they have in common.
Mercury, Venus, Earth, and Mars can all be categorized as Terrestrial Planets (Rocky Planets), Jupiter and Saturn can be categorized as Gas Giants, and Uranus and Neptune can be categorized as Ice Giants.
What does the term Comet mean?
A Comet is a small, icy body in space that orbits the Sun. It is made mostly of ice, dust, and rocky material. When a Comet gets close to the Sun the heat causes its ice to vaporize.
What does the term Asteroid mean?
An Asteroid is a small rocky object that orbits the Sun, they are mostly found in the region between Mars and Jupiter called the asteroid belt.
Describe how planets, asteroids, and other objects in our Solar System were formed.
Planets, asteroids, and other objects in our Solar System were formed from a giant cloud of gas and dust called nebula, which collapsed under its own gravity
How are Solar Systems in different parts of the Universe different from our own?
Solar Systems in different parts of the Universe are different from are own because of things such as planet types and sizes, different types of stars, planet orbits, number of planets, habitability and conditions.
How is Gravity the force that keeps objects in the Solar System in orbit around the Sun?
Gravity is the force that keeps objects in the Solar System in orbit around the Sun as Gravity is a force of attraction between objects that have mass. The more massive an object the stronger its gravity. The Sun is the most massive object in the solar system and its gravity pulls, planets, asteroids, comets, and other objects towards it and instead of falling into the Sun these objects move fast enough to stay in orbit.
Describe how Weight can change on different planets.
Weight can change on different planets because weight depends on gravity, and each planet has a different gravitational pull.
