How to use exoplanet in a sentence?

1. 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].

2. 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.

3. 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.

4. Heidi Hammel:

   By monitoring auroral activity on exoplanets, we may be able to infer the presence of water on or within an exoplanet, now, it's not going to be easy — it's not as easy as Ganymede and Jupiter, and that wasn't easy. It may require a much larger telescope than Hubble, it may require some future space telescope, but nevertheless, it's a tool now that we didn't have prior to this work that Joachim and his team have done.

5. Nora Eisner:

   That's why a lot of exoplanet candidates are missed, and why citizen science is great.
