WASP-8 is 293 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G8 V star; the first was found in 2010 by transit (SuperWASP).
Fly there in 3DWASP-8 b goes round its star every 8.16 days, 11 times as often as Mercury goes round the Sun.
WASP-8 is one of 2 stars in its system. The position of the other star is not catalogued, so only WASP-8 and its planets are drawn.

|---|---|---|---|---|---|
| WASP-8 b | 8.16 days | 0.0801 AU | 12.666 R⊕ | 807.29 M⊕ | Transit, 2010 |
| WASP-8 c | 11.8 years | 5.280 AU | 12.5 R⊕ estimated | 3003.4 M⊕ minimum | Radial Velocity, 2013 |
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 5,600 K, 0.88 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.90 to 1.59 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 293 years ago, around 1730.
