While the planets in our solar system have nearly circular orbits, astronomers have discovered several extrasolar planets with highly elliptical or eccentric orbits.
In the last 20 years, we have learned that extrasolar planets (planets orbiting other stars) do indeed exist, and more than 1,000 have now been cataloged.
He said that their result also demonstrates the power of this technique for measuring water and other molecules in the atmospheres of planets, giving us a new tool to study the nature and evolution of extrasolar planets.
The much sought-after wobble shows itself as an alteration in the time between two transits, which is how long it takes for the extrasolar planet to complete a single orbit around its star.
In 1992, astronomers used a similar method to make the first discoveries of extrasolar planets.
In 1991, English astronomer Andrew Lyne and his team announced the detection of planets around a pulsar (a dead star), which seemed to be the first extrasolar planets.

EPOXI is a combination of the names for the two extended mission components: a search for extrasolar planets during its cruise phase to comet Hartley 2, called Extrasolar Planet Observations and Characterization (EPOCh), and the eventual flyby of the comet, called the Deep Impact eXtended Investigation (DIXI).
