Gliese 581c

Gliese 581c is a planet that's not like Earth! It's called a 'super-Earth' because it's much bigger. Think of it like this: if Earth was a bouncy ball, Gliese 581c would be a big beach ball! It's about 6.8 times heavier than our home planet. This means it's a really chunky planet out there in space.

Gliese 581c lives in a special neighborhood in space called the Gliese 581 system. It's like having a star as a sun, and planets are its family members. Gliese 581c is the second planet to be found there, and it's the third one from its star. It's pretty far away, about 194 trillion kilometers! That's like driving your toy car around the Earth more times than you can count!

When scientists first found Gliese 581c, they got super excited! They thought it might be just right for water to be liquid on its surface, like in a puddle or a lake. If there's liquid water, maybe tiny little alien creatures, like super-tough germs, could live there! But now, scientists think it might be too hot for water to stay liquid.

Gliese 581c is closer to us than many other stars, only about 20.55 light-years away. That's still super, super far, but in space terms, it's like being in the next town over! It's located in a part of the sky called the constellation Libra, which looks like a weighing scale. So, this planet is a fascinating neighbor in our giant Milky Way galaxy.
