How do scientists find and confirm exoplanets orbiting distant stars?

Scientists use clever tricks to find and check exoplanets, planets that live far away around other stars.

Imagine you're on a swing, and someone is pushing you from behind. You can feel the push even if you don't see them. Scientists use something similar when looking for exoplanets.

When a planet orbits its star, it gives the star a tiny "push." This makes the star wobble, just like how you move on a swing when someone pushes you. Scientists watch this wobbling from Earth and say, “Hey, there must be a planet out there giving that star a push!”

Sometimes, scientists use another trick called a "transit", it's like when a toy blocks the light from a flashlight. When an exoplanet passes in front of its star, it blocks some of the star’s light. Scientists notice this dimming and know there must be a planet passing by!

Once they see these clues, wobbles or dips in brightness, scientists do more tests to make sure. They’re like detectives solving a mystery about faraway planets! Scientists use clever tricks to find and check exoplanets, planets that live far away around other stars.
