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 11
Calculate the approximate distance from the Sun to Neptune in astronomical units (AU), given that 1 AU is the average distance from the Earth to the Sun.
Describe the main components of the Solar System other than the Sun and planets.
Describe the main differences between terrestrial and Jovian planets in the Solar System.
Describe the role of gravity in maintaining the structure of the Solar System.
Explain the difference between an asteroid and a comet.
Explain why Pluto is classified as a dwarf planet and not a major planet.
Explain why the inner planets are rocky while the outer planets are gaseous.
If the average distance from the Earth to the Sun is 1 AU, and Mars is about 1.5 AU from the Sun, how much farther is Mars from the Sun compared to Earth?
A spacecraft travels from Earth to Jupiter. If the average distance from Earth to the Sun is 1 AU and from Jupiter to the Sun is 5.2 AU, calculate the minimum possible distance the spacecraft must travel, assuming both planets are aligned on the same side of the Sun.
Compare and contrast the characteristics and locations of the Kuiper Belt and the Oort Cloud.
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 Solar System is considered to be a nearly flat disk rather than a spherical distribution of planets and other objects.
If a planet orbits the Sun at an average distance of 9 AU, use Kepler's third law to estimate its orbital period in Earth years. (Assume the mass of the planet is negligible compared to the Sun.)
