One of the most important recent discoveries in astronomy has been our finding thousands of exoplanets, planets that orbit other stars besides the Sun. When a massive planet orbits a star, it will cause a wobble in its motion affecting the ____________ we measure over time. When a bigger planet blocks the light of the star as it _______, that can tell us the size of the planet and its __________. A type of planet that we don’t have in the solar system, but turns out to be common elsewhere is one that has two to ten times the mass of the planet we live on, called a ______________. One of the most challenging categories of exoplanets that we don’t have in our solar system is a type of planet with the mass of a giant planet in our system but orbiting very close to its star, called a ______________.
