From the Ted Talk "Lucianne Walkowicz: Finding planets around other stars"

#### Unscramble the Blue Letters

When we see these little dips in the light, we can rdenmteei a number of things. For one thing, we can determine that there's a planet there, but also how big that planet is and how far it is away from its parent star. That distance is really important because it tells us how much light the patenl eviseerc overall. And that distance and noinkwg that amount of light is important because it's a little like you or I sitting around a campfire: You want to be close enough to the campfire so that you're warm, but not so close that you're too toasty and you get burned.

When we see these little dips in the light, we can determine a number of things. For one thing, we can determine that there's a planet there, but also how big that planet is and how far it is away from its parent star. That distance is really important because it tells us how much light the planet receives overall. And that distance and knowing that amount of light is important because it's a little like you or I sitting around a campfire: You want to be close enough to the campfire so that you're warm, but not so close that you're too toasty and you get burned.
