How to use exoplanet in a sentence?

1. Sean Carey:

   Spitzer's helped us rewrite our textbooks, it changed our understanding of the universe. Robert Hurt told us fundamental things about exoplanet properties. We wouldn't know that the bulk of star formation occurred 10 billion years ago. And my son is going to learn about the TRAPPIST system in school next year.

2. Marshall Perrin:

   We're going to be opening up a lot of new discoveries, hopefully, over the next few years in terms of exoplanet imaging and, in the long run, taking these technologies and scaling them to future 30-meter telescopes, and perhaps large telescopes in space, to continue direct imaging and push down towards the Earth-like planet regime.

3. Hugh Osborn:

   Detecting this system is probably the easy bit, because the star is so small and the brown dwarf relatively large, the transit signal is actually about 10 times larger than that of [a typical exoplanet that turns up in surveys of the night sky].

4. Zachory Berta-Thompson:

   We think it’s the first opportunity we have to point our telescopes at a rocky exoplanet and get that kind of detail, to be able to measure the color of its sunset, or the speed of its winds, and really learn how rocky planets work out there in the universe, those will be exciting observations to make.

5. Jennifer Burt:

   One of the most intriguing results of the last two decades of exoplanet science is that, thus far, none of the new planetary systems we've discovered look anything like our own solar system, this new planet we've discovered is still weird -- but it's one step closer to being somewhat like our neighborhood planets.
