Front

What is the Oort Cloud?

Back

The Oort Cloud is a region that exists much further out than the Kuiper belt and is at the very edge of the Solar System. It is believed to be made up of thousands of icy bodies.

Front

List the planets in order from closest to furthest from the Sun: Venus, Earth, Mars, Jupiter, Saturn.

Back

Venus, Earth, Mars, Jupiter, Saturn.

Front

What determines the location of the habitable zone for each star?

Back

The size of the star determines where the habitable zone is located.

Front

What is the average temperature of a planet that is 'Earth distance' away from the Sun?

Back

57°F.

Front

Why does Jupiter have multiple moons while Earth has only one?

Back

Jupiter is a larger planet than Earth and has a larger gravitational attraction, which causes other objects to orbit it from a greater distance.

Front

What is the Kuiper Belt?

Back

The Kuiper Belt is a region of the Solar System beyond the orbit of Neptune, populated with many small icy bodies and dwarf planets.

Front

Define a dwarf planet.

Back

A dwarf planet is a celestial body that orbits the Sun and is similar to a planet but does not clear its neighboring region of other objects.

Front

What is the main difference between terrestrial and gas giant planets?

Back

Terrestrial planets are rocky and solid, while gas giants are composed mostly of gases and have no well-defined solid surface.

Front

What is the significance of the habitable zone?

Back

The habitable zone is the region around a star where conditions may be right for liquid water to exist, which is essential for life as we know it.

Front

What are asteroids?

Back

Asteroids are small rocky bodies that orbit the Sun, primarily found in the asteroid belt between Mars and Jupiter.
