What are cosmic imposters that can mislead astronomers?

Cosmic imposters are space objects that look like other space objects but are actually different, kind of like a wolf wearing a sheep’s skin!

Imagine you're playing hide and seek in the park, and someone hides behind a big tree. From far away, they look just like another kid who is also hiding. But when you get closer, you realize it's not your friend, it's a cosmic imposter!

Some stars are so far away that they appear as small, bright dots in the sky, just like planets do. But unlike planets, stars shine all by themselves. Astronomers sometimes get confused because these stars look like planets, but they're not! It's like thinking a flashlight is a firefly, both glow, but one needs batteries and the other doesn’t!

Sometimes, a distant object looks like it’s right next to us. Imagine seeing a toy car that looks like it’s in your hand, but it's actually on the other side of the street! That’s what happens with some cosmic imposters, they trick astronomers into thinking they're nearby when they're really far away.

Astronomers use special tools and tricks to tell the real ones from the fake ones, just like you would if you were playing hide and seek!
