extrasolar planet orbiting thestar GSC 03549-02811 located 750light year s away. The planet's mass and radius indicate that it is agas giant with a similar bulk composition toJupiter . Unlike Jupiter, but similar to many other planets detected around other stars, TrES-2 is located very close to its star, and belongs to the class of planets known as hot Jupiters.cite journal | url=http://www.journals.uchicago.edu/doi/abs/10.1086/509123 | author=O'Donovan "et al." | title=TrES-2: The First Transiting Planet in the Kepler Field | journal=TheAstrophysical Journal Letters | volume=651 | year=2006 | pages= L61 – L64 ( [http://xxx.lanl.gov/abs/astro-ph?papernum=0609335 web Preprint] )]Discovery
TrES-2 was discovered by the
Trans-Atlantic Exoplanet Survey by detecting the transit of the planet across its parent star using Sleuth (Palomar Observatory ,California ) and PSST (Lowell Observatory ,Arizona ), part of the TrES network of 10–cm telescopes. The discovery was confirmed by theKeck Observatory .Rotation
As of August 2008, the most recent calculation of TrES-2's
Rossiter-McLaughlin effect and so spin-orbit angle was that of Winn. [cite arXiv | title= Measuring accurate transit parameters | author=Joshua N. Winn | eprint=0807.4929v2 |class=astro-ph |year=2008] This is −9 ± 12 degrees. [cite journal |journal=Astrophysical Journal |issue=682|page= 1283| title= | author=Winn "et al." |year=2008]ee also
