Solar System Structure starts at 6 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Solar System Structure. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Calculate the approximate average distance from the Earth to the Sun in astronomical units (AU).
Describe the heliocentric model of the Solar System.
Describe the main components of the Solar System other than the Sun and planets.
Describe the main differences between terrestrial and Jovian planets.
Explain the difference between an asteroid and a comet.
Explain why Pluto is no longer classified as a major planet.
If a planet orbits the Sun at an average distance of 4 AU, use Kepler's third law to estimate its orbital period in Earth years.
If the average distance from the Sun to Neptune is about 30 AU, how many times farther is Neptune from the Sun compared to Earth?
Name the four terrestrial planets in the Solar System.
Which planet has the highest average surface temperature in the Solar System?
Which planet has the most extensive ring system in the Solar System?
A hypothetical planet orbits the Sun at a mean distance of 16 AU. Using Kepler's third law, calculate its orbital period in Earth years.
Context: A spacecraft is launched from Earth and travels directly outward from the Sun. As it passes the orbit of Mars, it encounters a region with a high density of small rocky bodies. Question: Identify this region and explain its significance in the structure of the Solar System.
Describe the process by which planetesimals formed during the early history of the Solar System.
Explain how the conservation of angular momentum influenced the formation and current structure of the Solar System.
Explain why the orbital planes of the planets are only slightly inclined relative to each other, and discuss the implications for the overall structure of the Solar System.
