TrES-2 is 702 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this G0 V star; the first was found in 2006 by transit (TrES).
Fly there in 3DTrES-2 b goes round its star every 2.47 days, 36 times as often as Mercury goes round the Sun.
TrES-2 is one of 2 stars in its system. The position of the other star is not catalogued, so only TrES-2 and its planets are drawn.

Values are the NASA Exoplanet Archive’s composite parameters. A radius marked estimated comes from a mass–radius relation; a mass marked minimum is M sin i. Planet sizes and colours in the 3D view are renderings: none of these worlds has been photographed as more than a point of light.
For a star of 5,850 K, 1.1 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.99 to 1.74 AU. None of its known planets orbits inside it. The zone says how much starlight arrives, not whether a planet has water or air. The edges follow Kopparapu et al. (2014), as the 3D view draws them.
The light you see left 702 years ago, around 1320.
