These mysterious worlds beyond our solar system, called exoplanets, could harbor life.
The satellite will seek to find exoplanets that have the most promising conditions for supporting life, NASA said.
"We can start to find out, how does planet occurrence vary as a function of the type of star and the age of the star?" "Kepler was a statistical survey that looked at a small patch of sky for four years and taught us that Earths are everywhere".
Closer, brighter host stars will also make it easier to eventually collect details about those planets - like what they're made of and what their atmospheres are like.

The satellite will figure out "the most promising exoplanets orbiting relatively nearby stars", providing future researchers with an exhaustive set of new targets for more follow-up studies, including the potential to determine "their capacity to harbor life", the USA space agency said. Further study can then be done by regular scientific telescopes.
Tess for short - is embarking Monday on a two-year quest to find and identify mystery worlds thought to be lurking in our cosmic backyard.
"TESS is equipped with four very sensitive cameras that will be able to monitor almost the entire sky", said George Ricker, TESS principal investigator at the Massachusetts Institute of Technology (MIT).
The satellite, TESS, is the US space agency's newest planet-hunting spacecraft that will search for undiscovered planets outside of our solar system, known as exoplanets. The stars that TESS plans to survey will be 30 to 100 times brighter than those observed by its predecessor.
The next step is for ground-based and space telescopes to peer even closer.
"TESS forms a bridge from what we have learned about exoplanets to date and where we are headed in the future", said Jeff Volosin, TESS project manager at Nasa's Goddard Spaceflight Centre.
A good numerous new planets will be relatively close - within a few dozen light-years of Earth. "The first thing is we're looking for is water vapor", says Sara Seager at MIT, "because all life, as we know it, needs liquid water".
