OtterKnow Kids EncyclopediaSpace is SO big that it is hard to even imagine! It goes on and on in every direction. Even the fastest rocket would take thousands of years to reach the nearest star outside our solar system.
Scientists think there are over 100 billion stars just in our galaxy. And there are billions of galaxies out there too! Space is also getting bigger every single day. It keeps stretching and growing, and no one knows where it ends.
- If you could drive a car to the Sun, it would take over 170 years to get there.
- Light from the nearest star takes over four years to reach us.
- The universe is about 13.8 billion years old, which is much, much older than the dinosaurs!
