Distances to objects in space are very, very large. The nearest star (excluding the Sun), Alpha Centauri, is 41.23 trillion km, or 41,320,000,000,000 km!!
We can see thousands of stars in the night sky - small points of light in the vastness of space. But what are stars? How do they make light? Why are they different colours? Watch this video to find out some more information about stars!
Do you know how many planets in our Solar System have rings? Or how many have moons? Learn some interesting facts about the planets in our Solar System with these free printable posters!
The Moon is locked with the Earth, which means that we always see the same side of the Moon. You would think that this meant that we could only see 50% of the Moon's surface, but we can see slightly more from Earth.
