TRAPPIST-1: A Star with Seven Worlds!

TRAPPIST-1 is a super cool star, but it's much smaller and dimmer than our Sun. It's like a tiny, warm ember in space! And guess what? It has SEVEN planets all to itself! These planets are called TRAPPIST-1b, c, d, e, f, g, and h. They are all rocky, like Earth, and some might even have oceans of water. How exciting is that for a space adventure?

TRAPPIST-1 is super old, even older than our own Solar System! It's about 7.6 billion years old. That's so long ago, it's hard to even imagine! This star is also very, very far away, about 40 light-years from Earth. If you wanted to travel there in a super-fast rocket, it would take you a very, very, very long time!

These seven planets have a very strange habit. They are 'tidally locked' to TRAPPIST-1. This means one side of each planet always faces the star, so it's always daytime there! The other side always faces away, so it's always nighttime. Imagine living where one side is always sunny and the other is always dark!

Scientists are super excited about TRAPPIST-1 because up to four of its planets are in a 'Goldilocks zone'. This means they are just the right distance from the star for liquid water to exist on their surface. Water is super important for life as we know it, so maybe, just maybe, there could be little alien friends living there!
