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
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.
A comet is observed to have a highly elliptical orbit that takes it far beyond Neptune. From which region of the Solar System is it most likely to have originated?
(1) Asteroid Belt

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.
