Kepler-454 is 753 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this 5,687 K star; the first was found in 2015 by transit (Kepler).
Fly there in 3DKepler-454 b goes round its star every 10.6 days, 8 times as often as Mercury goes round the Sun.
Kepler-454 is one of 2 stars in its system. The position of the other star is not catalogued, so only Kepler-454 and its planets are drawn.

|---|---|---|---|---|---|
| Kepler-454 b | 10.6 days | 0.0953 AU | 2.37 R⊕ | 5.4 M⊕ | Transit, 2015 |
| Kepler-454 c | 524.2 days | 1.287 AU | 12.9 R⊕ estimated | 1433.4 M⊕ minimum | Radial Velocity, 2015 |

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 5,687 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 1.02 to 1.80 AU. 1 of its 3 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.
