Question: Which is the biggest planet in our solar system?

Answer: In our solar system the largest planet is Jupiter, it is classed as a gas giant because it is mostly made up of gas.

Jupiter is the fifth planet from our sun, there a day lasts 9.9 hours and a year (one complete orbit of the sun) takes 12 Earth years.

Jupiter can be seen with the naked eye in the night sky, it appears very big and bright, only outshone by the moon and Venus.

Jupiter’s huge mass means it creates a very strong gravitational pull, as a result Jupiter has 63 moons orbiting it.

The four largest of which are Io, Europa, Ganymede and Callisto, even these can be seen though quite a basic telescope.
