10 Questions
What is the primary reason why asteroids have irregular shapes, unlike dwarf planets or planets?
Asteroids lack the specific amount of mass required to form a spherical shape.
What is the main difference between the gas tail and the dust tail of a comet?
The gas tail vaporizes when going from the cold Oort cloud to the hot sun and is pointed away by the solar wind, while the dust tail leaves a trail following the comet.
What is the main reason why some planets are considered terrestrial and others are considered gas giants?
Terrestrial planets are smaller, rocky, and have a high density, while gas giants are much larger, composed mostly of gases, and have a low density.
What is the main advantage of using probes over telescopes in space exploration?
Probes can visit multiple planets, collect information and images, and send them to Earth, while telescopes can only observe from a fixed location.
Why are human missions to other planets considered more expensive and risky than rover missions?
Human missions require a lot of supplies to support human life, and the risks involved are higher, including the risk of failure and the risk to human life.
What proportion of the mass of our solar system is taken up by the Sun?

What is the primary difference in composition between inner and outer planets?

What is the asteroid belt, and where is it located?
A region of space with 100,000 sparsely distributed asteroids, located between Mars and Jupiter.
What is the main difference between asteroids and meteors?
Asteroids are objects in space, while meteors are asteroids that enter the Earth's atmosphere and burn up.
