Space has always fascinated children and adults alike. The vast universe, sparkling stars, mysterious planets, and powerful galaxies spark curiosity about how everything works. One of the most interesting topics in science for young learners is the solar system. Learning about planets and space not only improves general knowledge but also encourages curiosity and scientific thinking.
Many children often ask questions such as what a planet is, how many planets there are in the solar system, and which planet is the largest. Asking and answering solar system GK questions helps children learn the basics of astronomy in a fun, interactive way.
In this article, we will explore the solar system, explain what a planet is, and provide a list of engaging GK questions on the solar system with answers that children can learn and enjoy.
What Is a Planet?
Before learning GK questions about the solar system, it is important to understand what a planet is.
A planet is a large object in space that orbits a star. In our solar system, all the planets revolve around the Sun. Planets do not produce their own light; instead, they reflect light from the Sun.
According to modern astronomy, a planet must meet three conditions:
- It must orbit the Sun.
- It must have enough gravity to form a round shape.
- It must have cleared its orbit of other objects.
There are eight planets in our solar system.

How EuroKids Builds Strong EVS Foundations
When Environmental Studies (EVS) is introduced through observation, storytelling, nature walks, and hands-on exploration, young learners begin to understand their surroundings in a meaningful and lasting way. Instead of memorising facts about plants, animals, or seasons, children learn by experiencing and questioning the world around them. This is why structured early education programs focus on experiential and inquiry-based learning rather than rote memorisation.
At EuroKids, foundational EVS concepts are nurtured through the HEUREKA – Visible Thinking Curriculum. This approach encourages children to explore themes such as “My Family,” “My Community,” “Plants and Animals,” “Seasons and Weather,” and “Good Habits” through interactive discussions, thematic projects, role play, outdoor exploration, and guided observation.
The Visible Thinking framework helps children observe carefully, think deeply, and express their ideas confidently. Through activities like nature-based learning, environmental awareness projects, sensory exploration, and group conversations, children develop curiosity about how things grow, how communities function, and how they can care for the environment.
With a child-centric, play-based methodology refined over 20+ years and implemented across 1,600+ preschools, EuroKids focuses on building awareness, responsibility, and curiosity first, allowing knowledge, empathy, and critical thinking skills to develop naturally over time.
