Scientists use clever tricks to find exoplanets, which are planets that go around stars other than our Sun, like how Earth goes around the Sun.
Imagine you're playing hide and seek with your friend in a big room. You can’t see them, but you can tell they’re there when the light from the lamp flickers because they move in front of it. Scientists use a similar idea.
Like a Hide-and-Seek Game
They watch stars closely. When a planet passes in front of its star from our viewpoint, the star gets slightly dimmer, like your friend blocking part of the light from the lamp. This is called the transit method. It’s how scientists know there are other planets out there.
What They've Found
They’ve found thousands of exoplanets! Some are giant and hot, like Jupiter. Others are small and might have water, maybe even life. One special planet is so close to its star that it takes just 10 hours to go around it, faster than your toy car goes around the kitchen table!
Scientists keep looking, using telescopes in space and on Earth, like a giant detective team solving the mystery of faraway worlds.
Examples
- The light from a faraway star flickers as a planet passes in front of it, helping scientists spot the hidden world.
- A small planet is discovered orbiting a distant star using a technique called the 'wobble method'."
